Please add some!
Sample Code:
Int32 iNewDataLen = 0;
Byte[] byNewData = null;
bool bDefaultChar = false;
iNewDataLen = WideCharToMultiByte(CP_ACP, 0, strData, strData.Length, null, 0, IntPtr.Zero, out bDefaultChar);
byNewData = new Byte[iNewDataLen + 2];
iNewDataLen = WideCharToMultiByte(CP_ACP, 0, strData, strData.Length, byNewData, iNewDataLen, IntPtr.Zero, out bDefaultChar);
