ToUInt16 Method (UInt64)

Convert.ToUInt16 Method (UInt64)

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

This API is not CLS-compliant. 

Namespace:  System
Assemblies:   System.Runtime.Extensions (in System.Runtime.Extensions.dll)
  mscorlib (in mscorlib.dll)

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

Parameters

value
Type: System.UInt64

The 64-bit unsigned integer to convert.

Return Value

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

ExceptionCondition
OverflowException

value is greater than UInt16.MaxValue.

The following example attempts to convert each element in an array of unsigned long integers to an unsigned 16-bit integer.

ulong[] numbers = { UInt64.MinValue, 121, 340, UInt64.MaxValue };
ushort result;

foreach (ulong 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: 
//    Converted the UInt64 value '0' to the UInt16 value 0. 
//    Converted the UInt64 value '121' to the UInt16 value 121. 
//    Converted the UInt64 value '340' to the UInt16 value 340. 
//    The UInt64 value 18446744073709551615 is outside the range of the UInt16 type.
