BitConverter.ToUInt16 Method
.NET Framework 4
Returns a 16-bit unsigned integer converted from two bytes at a specified position in a byte array.
Assembly: mscorlib (in mscorlib.dll)
[CLSCompliantAttribute(false)] public static ushort ToUInt16( byte[] value, int startIndex )
Parameters
- value
- Type: System.Byte[]
The array of bytes.
- startIndex
- Type: System.Int32
The starting position within value.
Return Value
Type: System.UInt16A 16-bit unsigned integer formed by two bytes beginning at startIndex.
| Exception | Condition |
|---|---|
| ArgumentException |
startIndex equals the length of value minus 1. |
| ArgumentNullException |
value is null. |
| ArgumentOutOfRangeException |
startIndex is less than zero or greater than the length of value minus 1. |
The following code example converts elements of Byte arrays to UInt16 values with the ToUInt16 method.
// Example of the BitConverter.ToUInt16 method. using System; class BytesToUInt16Demo { const string formatter = "{0,5}{1,17}{2,10}"; // Convert two byte array elements to a ushort and display it. public static void BAToUInt16( byte[ ] bytes, int index ) { ushort value = BitConverter.ToUInt16( bytes, index ); Console.WriteLine( formatter, index, BitConverter.ToString( bytes, index, 2 ), value ); } public static void Main( ) { byte[] byteArray = { 15, 0, 0, 255, 3, 16, 39, 255, 255, 127 }; Console.WriteLine( "This example of the BitConverter.ToUInt16( byte[ ], " + "int ) \nmethod generates the following output.
