MethodBuilder.SetImplementationFlags(MethodImplAttributes) MethodBuilder.SetImplementationFlags(MethodImplAttributes) MethodBuilder.SetImplementationFlags(MethodImplAttributes) MethodBuilder.SetImplementationFlags(MethodImplAttributes) Method

Definition

Sets the implementation flags for this method.

public:
 void SetImplementationFlags(System::Reflection::MethodImplAttributes attributes);
public void SetImplementationFlags (System.Reflection.MethodImplAttributes attributes);
member this.SetImplementationFlags : System.Reflection.MethodImplAttributes -> unit
Public Sub SetImplementationFlags (attributes As MethodImplAttributes)

Parameters

Exceptions

The containing type was previously created using CreateType().

-or-

For the current method, the IsGenericMethod property is true, but the IsGenericMethodDefinition property is false.

Examples

The code sample below illustrates the contextual use of the SetImplementationFlags method to describe the implementation of MSIL in a method body.

array<Type^>^ temp0 = { int::typeid, int::typeid };
MethodBuilder^ myMthdBuilder = myTypeBuilder->DefineMethod( "MyMethod",
                               MethodAttributes::Public,
                               CallingConventions::HasThis,
                               int::typeid,
                               temp0 );

// Specifies that the dynamic method declared above has a an MSIL implementation,
// is managed, synchronized (single-threaded) through the body, and that it
// cannot be inlined.

myMthdBuilder->SetImplementationFlags( (MethodImplAttributes)(
                                        MethodImplAttributes::IL |
                                        MethodImplAttributes::Managed |
                                        MethodImplAttributes::Synchronized |
                                        MethodImplAttributes::NoInlining) );

// Create an ILGenerator for the MethodBuilder and emit MSIL here ...
MethodBuilder myMthdBuilder = myTypeBuilder.DefineMethod("MyMethod",
					MethodAttributes.Public,
					CallingConventions.HasThis,
					typeof(int),
					new Type[] { typeof(int),
						     typeof(int) });	

// Specifies that the dynamic method declared above has a an MSIL implementation,
       // is managed, synchronized (single-threaded) through the body, and that it 
// cannot be inlined.

myMthdBuilder.SetImplementationFlags(MethodImplAttributes.IL |
				     MethodImplAttributes.Managed |
				     MethodImplAttributes.Synchronized |
				     MethodImplAttributes.NoInlining);

// Create an ILGenerator for the MethodBuilder and emit MSIL here ...

Dim myMthdBuilder As MethodBuilder = myTypeBuilder.DefineMethod("MyMethod", _
  MethodAttributes.Public, _
  CallingConventions.HasThis, _
  GetType(Integer), _
  New Type() {GetType(Integer), GetType(Integer)})

' Specifies that the dynamic method declared above has a an MSIL implementation,
' is managed, synchronized (single-threaded) through the body, and that it 
' cannot be inlined.

myMthdBuilder.SetImplementationFlags((MethodImplAttributes.IL Or _
   MethodImplAttributes.Managed Or _
   MethodImplAttributes.Synchronized Or _
   MethodImplAttributes.NoInlining))

' Create an ILGenerator for the MethodBuilder and emit MSIL here ...

Remarks

When you use the SetImplementationFlags method in combination with the SetCustomAttribute method, be aware of potential interactions. For example, using the SetCustomAttribute method to add the DllImportAttribute attribute also sets the MethodImplAttributes.PreserveSig flag. If you subsequently call the SetImplementationFlags method, the PreserveSig flag is overwritten. There are two ways to avoid this:
