BitConverter::ToUInt16 Method
Visual Studio 2010
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 unsigned short ToUInt16( array<unsigned char>^ value, int startIndex )
Parameters
- value
- Type: array<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 nullptr. |
| 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 namespace System; // Convert two byte array elements to an unsigned short and display it. void BAToUInt16( array<unsigned char>^bytes, int index ) { unsigned short value = BitConverter::ToUInt16( bytes, index ); Console::WriteLine( "{0,5}{1,17}{2,16}", index, BitConverter::ToString( bytes, index, 2 ), value ); } int main() { array<unsigned char>^byteArray = {15,0,0,255,3,16,39,255,255,127}; Console::WriteLine( "This example of the BitConverter::ToUInt16( unsigned " "char[ ], int ) \nmethod generates the following output. It " "converts elements of a \nbyte array to unsigned short " "values.\n" ); Console::WriteLine( "initial byte array" ); Console::WriteLine( "------------------" ); Console::WriteLine( BitConverter::ToString( byteArray ) ); Console::WriteLine(); Console::WriteLine( "{0,5}{1,17}{2,16}", "index", "array elements", "unsigned short" ); Console::WriteLine( "{0,5}{1,17}{2,16}", "-----", "--------------", "--------------" ); // Convert byte array elements to unsigned short values. BAToUInt16( byteArray, 1 ); BAToUInt16( byteArray, 0 ); BAToUInt16( byteArray, 3 ); BAToUInt16( byteArray, 5 ); BAToUInt16( byteArray, 8 ); BAToUInt16( byteArray, 7 ); } /* This example of the BitConverter::ToUInt16( unsigned char[ ], int ) method generates the following output.
