Default Marshaling for Characters

  • Article

When a managed Char type, which has Unicode formatting by default, is passed to unmanaged code, the interop marshaler converts the character set to ANSI. You can apply the DllImportAttribute attribute to platform invoke declarations and the StructLayoutAttribute attribute to a COM interop declaration to control which character set a marshaled Char type uses.
