Convert.ToUInt64 Method (Byte)

Converts the value of the specified 8-bit unsigned integer to the equivalent 64-bit unsigned integer.

This API is not CLS-compliant. 

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

[CLSCompliantAttribute(false)]
public static ulong ToUInt64(
	byte value
)

Parameters

value
Type: System.Byte
The 8-bit unsigned integer to convert.

Return Value

Type: System.UInt64
A 64-bit signed integer that is equivalent to value.

The following example converts each element in a byte array to an unsigned long integer.


byte[] bytes = { Byte.MinValue, 14, 122, Byte.MaxValue};
ulong result;

foreach (byte byteValue in bytes)
{
   result = Convert.ToUInt64(byteValue);
   Console.WriteLine("Converted the {0} value {1} to the {2} value {3}.",
                     byteValue.GetType().Name, byteValue,
                     result.GetType().Name, result);
}
// The example displays the following output:
//    Converted the Byte value 0 to the UInt64 value 0.
//    Converted the Byte value 14 to the UInt64 value 14.
//    Converted the Byte value 122 to the UInt64 value 122.
//    Converted the Byte value 255 to the UInt64 value 255.
