Keterangan

Int32 adalah jenis nilai yang tidak dapat diubah yang mewakili bilangan bulat yang ditandatangani dengan nilai yang berkisar dari negatif 2.147.483.648 (yang diwakili oleh Int32.MinValue konstanta) melalui positif 2.147.483.647 (yang diwakili oleh Int32.MaxValue konstanta). .NET juga menyertakan jenis nilai bilangan bulat 32-bit yang tidak ditandatangani, UInt32, yang mewakili nilai yang berkisar antara 0 hingga 4.294.967.295.

Menginisialisasi nilai Int32

Anda dapat menginstansiasi nilai Int32 dengan beberapa cara:

• Anda dapat mendeklarasikan variabel Int32 dan menetapkannya nilai bilangan bulat harfiah yang berada dalam rentang jenis data Int32. Contoh berikut mendeklarasikan dua variabel Int32 dan menetapkan nilainya dengan cara ini.

  int number1 = 64301;
  int number2 = 25548612;
  

  let number1 = 64301
  let number2 = 25548612
  

  Dim number1 As Integer = 64301
  Dim number2 As Integer = 25548612
  

• Anda dapat menetapkan nilai jenis bilangan bulat yang rentangnya merupakan subset dari jenis tersebut Int32 . Ini adalah konversi perluasan yang tidak memerlukan operator cast di C# atau metode konversi di Visual Basic, tetapi memerlukannya di F#.

  sbyte value1 = 124;
  short value2 = 1618;
  
  int number1 = value1;
  int number2 = value2;
  

  let value1 = 124y
  let value2 = 1618s
  
  let number1 = int value1
  let number2 = int value2
  

  Dim value1 As SByte = 124
  Dim value2 As Int16 = 1618
  
  Dim number1 As Integer = value1
  Dim number2 As Integer = value2
  

• Anda dapat menetapkan nilai jenis numerik yang rentangnya melebihi jenis Int32. Ini adalah konversi yang mempersempit, sehingga memerlukan operator cast di C# atau F#, dan metode konversi di Visual Basic jika Option Strict aktif. Jika nilai numerik adalah nilai Single, Double, atau Decimal yang menyertakan komponen pecahan, penanganan bagian pecahannya tergantung pada pengkompilasi yang melakukan konversi. Contoh berikut melakukan konversi yang mempersempit untuk menetapkan beberapa nilai numerik ke variabel Int32.

  long lNumber = 163245617;
  try {
     int number1 = (int) lNumber;
     Console.WriteLine(number1);
  }
  catch (OverflowException) {
     Console.WriteLine($"{lNumber} is out of range of an Int32.");
  }
  
  double dbl2 = 35901.997;

     int number2 = (int) dbl2;
     Console.WriteLine(number2);

• Anda dapat memanggil metode kelas Convert untuk mengonversi jenis yang didukung menjadi nilai Int32. Ini dimungkinkan karena Int32 mendukung antarmuka IConvertible. Contoh berikut mengilustrasikan konversi array nilai Decimal ke nilai Int32.

  decimal[] values= { Decimal.MinValue, -1034.23m, -12m, 0m, 147m,
                      199.55m, 9214.16m, Decimal.MaxValue };
  int result;
  
  foreach (decimal value in values)
  {
     try {
        result = Convert.ToInt32(value);
        Console.WriteLine("Converted the {0} value '{1}' to the {2} value {3}.",
                          value.GetType().Name, value,
                          result.GetType().Name, result);
     }
     catch (OverflowException) {
        Console.WriteLine("{0} is outside the range of the Int32 type.",
                          value);
     }
  }
  // The example displays the following output:
  //    -79228162514264337593543950335 is outside the range of the Int32 type.

• Anda dapat memanggil metode Parse atau TryParse untuk mengonversi representasi string dari nilai Int32 menjadi Int32. String dapat berisi digit desimal atau heksadesimal. Contoh berikut mengilustrasikan operasi penguraian dengan menggunakan string desimal dan heksadesimal.

  string string1 = "244681";
  try {
     int number1 = Int32.Parse(string1);
     Console.WriteLine(number1);
  }
  catch (OverflowException) {
     Console.WriteLine($"'{string1}' is out of range of a 32-bit integer.");
  }
  catch (FormatException) {
     Console.WriteLine($"The format of '{string1}' is invalid.");
  }
  
  string string2 = "F9A3C";
  try {
     int number2 = Int32.Parse(string2,
                              System.Globalization.NumberStyles.HexNumber);

Melakukan operasi pada nilai Int32

Jenis Int32 mendukung operasi matematika standar seperti penambahan, pengurangan, pembagian, perkalian, negasi, dan negasi unary. Seperti tipe integral lainnya, tipe Int32 juga mendukung operator bitwise AND, OR, XOR, shift kiri, dan shift kanan.

Anda dapat menggunakan operator numerik standar untuk membandingkan dua nilai Int32, atau Anda dapat memanggil metode CompareTo atau Equals.

Anda juga dapat memanggil anggota kelas Math untuk melakukan berbagai operasi numerik, termasuk mendapatkan nilai absolut angka, menghitung kuota dan sisanya dari pembagian integral, menentukan nilai maksimum atau minimum dua bilangan bulat, mendapatkan tanda angka, dan membulatkan angka.

Mewakili Int32 sebagai string

Jenis Int32 menyediakan dukungan penuh untuk string format numerik standar dan kustom. (Untuk informasi selengkapnya, lihat Jenis Pemformatan, String Format Numerik Standar, dan String Format Numerik Kustom.)

Untuk memformat nilai Int32 sebagai string integral tanpa nol di depan, Anda dapat memanggil metode ToString() tanpa parameter. Dengan menggunakan penentu format "D", Anda juga dapat menyertakan jumlah nol di depan tertentu dalam representasi string. Dengan menggunakan penentu format "N", Anda dapat menyertakan pemisah grup dan menentukan jumlah digit desimal yang akan muncul dalam representasi string angka. Dengan menggunakan penentu format "X", Anda dapat mewakili nilai Int32 sebagai string heksadesimal. Contoh berikut memformat elemen dalam array nilai Int32 dengan empat cara ini.

int[] numbers = { -1403, 0, 169, 1483104 };
foreach (int number in numbers)
{
    // Display value using default formatting.
    Console.Write("{0,-8}  -->   ", number.ToString());
    // Display value with 3 digits and leading zeros.
    Console.Write("{0,11:D3}", number);
    // Display value with 1 decimal digit.
    Console.Write("{0,13:N1}", number);
    // Display value as hexadecimal.
    Console.Write("{0,12:X2}", number);
    // Display value with eight hexadecimal digits.
    Console.WriteLine("{0,14:X8}", number);
}
// The example displays the following output:
//    -1403     -->         -1403     -1,403.0    FFFFFA85      FFFFFA85

let numbers = [| -1403; 0; 169; 1483104 |]
for number in numbers do
    // Display value using default formatting.
    printf $"{number,-8}  -->   "
    // Display value with 3 digits and leading zeros.
    printf $"{number,11:D3}"
    // Display value with 1 decimal digit.
    printf $"{number,13:N1}"
    // Display value as hexadecimal.
    printf $"{number,12:X2}"
    // Display value with eight hexadecimal digits.
    printfn $"{number,14:X8}"

Anda juga dapat memformat nilai Int32 sebagai string biner, oktal, desimal, atau heksadesimal dengan memanggil metode ToString(Int32, Int32) dan menyediakan basis sebagai parameter kedua metode. Contoh berikut memanggil metode ini untuk menampilkan representasi biner, oktal, dan heksadesimal dari array nilai bilangan bulat.

int[] numbers = { -146, 11043, 2781913 };
Console.WriteLine("{0,8}   {1,32}   {2,11}   {3,10}",
                  "Value", "Binary", "Octal", "Hex");
foreach (int number in numbers)
{
    Console.WriteLine("{0,8}   {1,32}   {2,11}   {3,10}",
                      number, Convert.ToString(number, 2),
                      Convert.ToString(number, 8),
                      Convert.ToString(number, 16));
}

Bekerja dengan nilai bilangan bulat 32-bit bukan desimal

Selain bekerja dengan bilangan bulat individual sebagai nilai desimal, Anda mungkin ingin melakukan operasi bitwise dengan nilai bilangan bulat, atau bekerja dengan representasi biner atau heksadesimal dari nilai bilangan bulat. Int32 nilai diwakili dalam 31 bit, dengan bit ke-32 digunakan sebagai bit tanda. Nilai positif diwakili dengan menggunakan representasi tanda dan besaran. Nilai negatif berada dalam representasi pelengkap dua dalam sistem bilangan biner. Ini penting untuk diingat ketika Anda melakukan operasi bitwise pada nilai Int32 atau ketika Anda bekerja dengan bit individual. Untuk melakukan operasi numerik, Boolean, atau perbandingan pada dua nilai non-desimal, kedua nilai harus menggunakan representasi yang sama.

Keamanan Thread

Semua anggota jenis ini aman utas. Anggota yang tampaknya mengubah status instans benar-benar mengembalikan instans baru yang diinisialisasi dengan nilai baru. Seperti halnya jenis lain, membaca dan menulis ke variabel bersama yang berisi instans jenis ini harus dilindungi oleh kunci untuk menjamin keamanan utas.
