UInt32.MaxValue Field

Represents the largest possible value of UInt32. This field is constant.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)
public const uint MaxValue

The value of this constant is 4,294,967,295; that is, hexadecimal 0xFFFFFFFF.

The following example uses the MinValue and MaxValue fields to verify that an Int64 value is within the range of the UInt32 type before it performs a type conversion. This verification prevents an OverflowException at run time.

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);
}
