CompilerMarshalOverride Class


Indicates that the modified instance of a variable differs from its true type when marshaling. This class cannot be inherited.

Public Class CompilerMarshalOverride


The CompilerMarshalOverride class allows the common language runtime to marshal using the correct sizes.

Some behaviors of the common language runtime are incompatible with some languages. For example, C++ treats Boolean variables as single-byte values, while the common language runtime marshals them as four-byte values to match the BOOLEAN type defined by the Microsoft Windows API. To work around such issues, the C++ compiler emits this modifier on any wchar_t or bool parameter or function return.
