MethodImplAttributes Enumeration

Specifies flags for the attributes of a method implementation.

Namespace: System.Reflection
Assembly: mscorlib (in mscorlib.dll)

Syntax

Visual Basic (Declaration)

<ComVisibleAttribute(True)> _
Public Enumeration MethodImplAttributes

Visual Basic (Usage)

Dim instance As MethodImplAttributes

[ComVisibleAttribute(true)]
public enum MethodImplAttributes

Members

	Member name	Description
	CodeTypeMask	Specifies flags about code type.
	IL	Specifies that the method implementation is in Microsoft intermediate language (MSIL).
	Native	Specifies that the method implementation is native.
	OPTIL	Specifies that the method implementation is in Optimized Intermediate Language (OPTIL).
	Runtime	Specifies that the method implementation is provided by the runtime.
	ManagedMask	Specifies whether the code is managed or unmanaged.
	Unmanaged	Specifies that the method implementation is unmanaged.
	Managed	Specifies that the method implementation is managed.
	ForwardRef	Specifies that the method is not defined.
	PreserveSig	Specifies that the method signature is exported exactly as declared.
	InternalCall	Specifies an internal call.
	Synchronized	Specifies that the method is single-threaded through the body. Static methods (Shared methods in Visual Basic) lock on the type, whereas instance methods lock on the instance. You can also use the C# lock statement or the Visual Basic Lock function for this purpose.
	NoInlining	Specifies that the method cannot be inlined.
	NoOptimization	Specifies that the method is not optimized by the just-in-time (JIT) compiler when debugging possible code generation problems.
	MaxMethodImplVal	Specifies a range check value.

Remarks

The attributes are combined using the bitwise OR operation.

Managed masks:

Implementation information and interop masks:

Note:
Locking on the instance or on the type, for example, by using the Synchronized flag, is not recommended for public types because code other than your own can take locks on public types and instances. This might cause deadlocks.
