This enumeration specifies the character set that is used for marshaled strings. It is used by DllImportAttribute and StructLayoutAttribute.

Ansi marshals strings using one-byte ANSI characters, while Unicode uses two bytes to represent a single Unicode character. The Auto value is used only for PInvoke and specifies that PInvoke should decide how to marshal the strings based on your operating system (Unicode for Windows NT/2000/XP and ANSI for Windows 9x/Me).

public enum CharSet {
   None = 1,
   Ansi = 2,
   Unicode = 3,
   Auto = 4
