Convert.ToUInt16 Method (Int64)

Converts the value of the specified 64-bit signed integer to an equivalent 16-bit unsigned integer.

This API is not CLS-compliant. 

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

[CLSCompliantAttribute(false)]
public static ushort ToUInt16(
	long value
)

Parameters

value
Type: System.Int64

The 64-bit signed integer to convert.

Return Value

Type: System.UInt16
A 16-bit unsigned integer that is equivalent to value.

ExceptionCondition
OverflowException

value is less than zero or greater than UInt16.MaxValue.

The following example converts each element in a long integer array to an unsigned 16-bit integer.

long[] numbers = { Int64.MinValue, -1, 0, 121, 340, Int64.MaxValue };
ushort result;

foreach (long number in numbers)
{
   try {
      result = Convert.ToUInt16(number);
      Console.WriteLine("Converted the {0} value '{1}' to the {2} value {3}.", 
                        number.GetType().Name, number, 
                        result.GetType().Name, result);
   }                     
   catch (OverflowException) {
      Console.WriteLine("The {0} value {1} is outside the range of the UInt16 type.",
                        number.GetType().Name, number);
   }
}
// The example displays the following output: 
//    The Int64 value -9223372036854775808 is outside the range of the UInt16 type. 
//    The Int64 value -1 is outside the range of the UInt16 type. 
//    Converted the Int64 value '0' to the UInt16 value 0. 
//    Converted the Int64 value '121' to the UInt16 value 121. 
//    Converted the Int64 value '340' to the UInt16 value 340. 
//    The Int64 value 9223372036854775807 is outside the range of the UInt16 type.
