Convert.ToInt64 Method (Int16)

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

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

public static long ToInt64(
	short value
)

Parameters

value
Type: System.Int16

The 16-bit signed 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 integers to a long integer.

short[] numbers= { Int16.MinValue, -1, 0, 121, 340, Int16.MaxValue };
long result;

foreach (short number in numbers)
{
   result = Convert.ToInt64(number);
   Console.WriteLine("Converted the {0} value {1} to a {2} value {3}.",
                        number.GetType().Name, number,
                        result.GetType().Name, result);
}
// The example displays the following output: 
//    Converted the Int16 value -32768 to a Int32 value -32768. 
//    Converted the Int16 value -1 to a Int32 value -1. 
//    Converted the Int16 value 0 to a Int32 value 0. 
//    Converted the Int16 value 121 to a Int32 value 121. 
//    Converted the Int16 value 340 to a Int32 value 340. 
//    Converted the Int16 value 32767 to a Int32 value 32767.
