Convert.ToInt64 Method (UInt32)

 

Converts the value of the specified 32-bit unsigned integer to an equivalent 64-bit signed integer.

This API is not CLS-compliant.

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

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

Parameters

value
Type: System.UInt32

The 32-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 unsigned integers to a long integer.

uint[] numbers = { UInt32.MinValue, 121, 340, UInt32.MaxValue };
long result;
foreach (uint number in numbers)
{
   result = Convert.ToInt64(number);
   Console.WriteLine("Converted the {0} value {1:N0} to the {2} value {3:N0}.",
                     number.GetType().Name, number,
                     result.GetType().Name, result);
}
// The example displays the following output:
//    Converted the UInt32 value 0 to the Int64 value 0.
//    Converted the UInt32 value 121 to the Int64 value 121.
//    Converted the UInt32 value 340 to the Int64 value 340.
//    Converted the UInt32 value 4,294,967,295 to the Int64 value 4,294,967,295.
