Returns a Unicode character converted from two bytes at a specified position in a byte array.
Assembly: mscorlib (in mscorlib.dll)
Parameters
- value
- Type: System.Byte[]
An array.
- startIndex
- Type: System.Int32
The starting position within value.
| Exception | Condition |

| 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 Char values (Unicode characters) with the ToChar method.
// Example of the BitConverter.ToChar method. using System; class BytesToCharDemo { const string formatter = "{0,5}{1,17}{2,8}"; // Convert two byte array elements to a char and display it. public static void BAToChar( byte[] bytes, int index ) { char value = BitConverter.ToChar( bytes, index ); Console.WriteLine( formatter, index, BitConverter.ToString( bytes, index, 2 ), value ); } public static void Main( ) { byte[] byteArray = { 32, 0, 0, 42, 0, 65, 0, 125, 0, 197, 0, 168, 3, 41, 4, 172, 32 }; Console.WriteLine( "This example of the BitConverter.ToChar( byte[ ], " + "int ) \nmethod generates the following output. It " + "converts \nelements of a byte array to char values.\n" ); Console.WriteLine( "initial byte array" ); Console.WriteLine( "------------------" ); Console.WriteLine( BitConverter.ToString( byteArray ) ); Console.WriteLine( ); Console.WriteLine( formatter, "index", "array elements", "char" ); Console.WriteLine( formatter, "-----", "--------------", "----" ); // Convert byte array elements to char values. BAToChar( byteArray, 0 ); BAToChar( byteArray, 1 ); BAToChar( byteArray, 3 ); BAToChar( byteArray, 5 ); BAToChar( byteArray, 7 ); BAToChar( byteArray, 9 ); BAToChar( byteArray, 11 ); BAToChar( byteArray, 13 ); BAToChar( byteArray, 15 ); } } /* This example of the BitConverter.ToChar( byte[ ], int ) method generates the following output.
