UInt32.MaxValue Bidang

Definisi

Ruang nama:

System

Rakitan:

System.Runtime.dll

Sumber:

UInt32.cs

Mewakili nilai terbesar yang mungkin dari UInt32. Bidang ini konstan.

public: System::UInt32 MaxValue = 4294967295;

public const uint MaxValue = 4294967295;

val mutable MaxValue : uint32

Public Const MaxValue As UInteger  = 4294967295

Nilai Bidang

Value = 4294967295

UInt32

Contoh

Contoh berikut menggunakan MinValue bidang dan MaxValue untuk memverifikasi bahwa Int64 nilai berada dalam rentang jenis UInt32 sebelum melakukan konversi jenis. Verifikasi ini mencegah pada OverflowException durasi.

long longValue = long.MaxValue / 2;
uint integerValue; 

if (longValue <= uint.MaxValue && 
    longValue >= uint.MinValue)
{    
   integerValue = (uint) longValue;
   Console.WriteLine("Converted long integer value to {0:n0}.", 
                     integerValue);
}   
else
{
   uint rangeLimit;
   string relationship;
   
   if (longValue > uint.MaxValue)
   {
      rangeLimit = uint.MaxValue;
      relationship = "greater";
   }   
   else
   {
      rangeLimit = uint.MinValue;
      relationship = "less";
   }       

   Console.WriteLine("Conversion failure: {0:n0} is {1} than {2:n0}",  
                     longValue, 
                     relationship, 
                     rangeLimit);
}

let longValue = Int64.MaxValue / 2L

if longValue <= int64 UInt32.MaxValue && longValue >= int64 UInt32.MinValue then
    let integerValue = uint longValue 
    printfn $"Converted long integer value to {integerValue:n0}."
