Indicates whether string data fields within the class should be marshaled as LPWSTR or LPSTR by default.
Assembly: mscorlib (in mscorlib.dll)
If the CharSet field is set to CharSet.Unicode, all string arguments are converted to Unicode characters (LPWSTR) before they are passed to the unmanaged implementation. If the field is set to CharSet.Ansi, the strings are converted to ANSI strings (LPSTR). If the CharSet field is set to CharSet.Auto, the conversion is platform-dependent (ANSI on Windows 98 and Windows Me, and Unicode on later versions).
