DisableRuntimeMarshallingAttribute Class

Definition

Namespace:

System.Runtime.CompilerServices

Assembly:

System.Runtime.dll

Disables the built-in runtime managed/unmanaged marshalling subsystem for P/Invokes, Delegate types, and unmanaged function pointer invocations.

Remarks

The built-in marshalling subsystem has some behaviors that cannot be changed due to backward-compatibility requirements. This attribute allows disabling the built-in subsystem and instead uses the following rules for P/Invokes, Delegates, and unmanaged function pointer invocations:

• All value types that do not contain reference type fields recursively (unmanaged in C#) are blittable.
• Value types that recursively have any fields that have [StructLayout(LayoutKind.Auto)] are disallowed from interop.
• All reference types are disallowed from usage in interop scenarios.
• SetLastError support in P/Invokes is disabled.
• varargs support is disabled.
• LCIDConversionAttribute support is disabled.

Constructors

DisableRuntimeMarshallingAttribute()

Initializes a DisableRuntimeMarshallingAttribute instance with default values.

Properties

TypeId

When implemented in a derived class, gets a unique identifier for this Attribute. (Inherited from Attribute)

Methods

Equals(Object)	Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute)
GetHashCode()	Returns the hash code for this instance. (Inherited from Attribute)
GetType()	Gets the Type of the current instance. (Inherited from Object)
IsDefaultAttribute()	When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute)
Match(Object)	When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
ToString()	Returns a string that represents the current object. (Inherited from Object)
