Name
UnmanagedMarshal
Synopsis
This class defines how parameters or fields should be marshaled in
function calls to unmanaged code. By default, the CLR applies certain
format conversions automatically during this marshaling (for example, it might
change a System.String object to an unmanaged BSTR).
Use this class to override this default behavior.
To create an instance of this class, use one of the static methods to define the
unmanaged type you want. Typically, you will use DefineUnmanagedMarshal()
for this purpose, and specify the unmanaged type using the System.Runtime.InteropServices.UnmanagedType enumeration.
Alternatively, use DefineByValTStr() to
specify marshaling to a string in a fixed array buffer, and specify the other methods
for various types of unmanaged arrays. These static methods all return a UnmanagedMarshal object, with its
read-only properties set accordingly. Lastly, associate the UnmanagedMarshal with the appropriate
type using the SetMarshal()
method for the ParameterBuilder, MethodBuilder, or FieldBuilder class.
