Field Value

Examples

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);
}

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" 
 else
 UInt32.MinValue, "less" 

 printfn $"Conversion failure: {longValue:n0} is {relationship} than {rangeLimit:n0}"

Dim longValue As Long = Long.MaxValue \ 2
Dim integerValue As UInteger 

If longValue <= UInteger.MaxValue AndAlso _
 longValue >= UInteger.MinValue Then
 integerValue = CUInt(longValue)
 Console.WriteLine("Converted long integer value to {0:n0}.", _
 integerValue)
Else
 Dim rangeLimit As UInteger
 Dim relationship As String
 
 If longValue > UInteger.MaxValue Then
 rangeLimit = UInteger.MaxValue
 relationship = "greater"
 Else
 rangeLimit = UInteger.MinValue
 relationship = "less"
 End If 

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

Remarks

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