Convert.ToInt64 Method (UInt16)

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

This API is not CLS-compliant. 

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

[CLSCompliantAttribute(false)]
public static long ToInt64(
	ushort value
)

Parameters

value
Type: System.UInt16

The 16-bit unsigned integer to convert.

Return Value

Type: System.Int64
A 64-bit signed integer that is equivalent to value.

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

ushort[] numbers = { UInt16.MinValue, 121, 340, UInt16.MaxValue };
long result;
foreach (ushort number in numbers)
{
   try {
      result = Convert.ToInt64(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 Int64 type.",
                        number.GetType().Name, number);
   }
}
// The example displays the following output: 
//    Converted the UInt16 value 0 to the Int64 value 0. 
//    Converted the UInt16 value 121 to the Int64 value 121. 
//    Converted the UInt16 value 340 to the Int64 value 340. 
//    Converted the UInt16 value 65535 to the Int64 value 65535.
