C # in a Nutshell, Second Edition

This optional attribute is used to explicitly specify the unmanaged type a parameter, field, or return value should be marshaled to. If you do not specify this attribute, .NET uses the type's default marshaler . The UnmanagedType enumeration contains the unmanaged types you can marshal to with this attribute.

public sealed class MarshalAsAttribute : Attribute { // Public Constructors public MarshalAsAttribute (short unmanagedType ); public MarshalAsAttribute (UnmanagedType unmanagedType ); // Public Instance Fields public UnmanagedType ArraySubType ; public string MarshalCookie ; public string MarshalType ; public Type MarshalTypeRef ; public VarEnum SafeArraySubType ; public Type SafeArrayUserDefinedSubType ; public int SizeConst ; public short SizeParamIndex ; // Public Instance Properties public UnmanagedType Value {get; } }
