UInt32.MaxValue Campo

Definición

Representa el mayor valor posible de UInt32. Este campo es constante.

public: System::UInt32 MaxValue = 4294967295;
public const uint MaxValue = 4294967295;
val mutable MaxValue : uint32
Public Const MaxValue As UInteger  = 4294967295

Valor de campo

Value = 4294967295

Ejemplos

En el ejemplo siguiente se usan los MinValue campos y MaxValue para comprobar que un Int64 valor está dentro del intervalo del tipo antes de UInt32 realizar una conversión de tipos. Esta comprobación impide una OverflowException en tiempo de ejecución.

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}." 
else
    let rangeLimit, relationship = 
        if longValue > int64 UInt32.MaxValue then
            UInt32.MaxValue, "greater"
