ConstructorBuilder.SetImplementationFlags Method (MethodImplAttributes)


Sets the method implementation flags for this constructor.

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

public void SetImplementationFlags(
	MethodImplAttributes attributes


Type: System.Reflection.MethodImplAttributes

The method implementation flags.

Exception Condition

The containing type has been created using CreateType.

The following code sample illustrates the use of SetImplementationFlags.

MethodBuilder myMethodBuilder = null;
AppDomain myCurrentDomain = AppDomain.CurrentDomain;
// Create assembly in current CurrentDomain.
AssemblyName myAssemblyName = new AssemblyName();
myAssemblyName.Name = "TempAssembly";
// Create a dynamic assembly.
myAssemblyBuilder = myCurrentDomain.DefineDynamicAssembly
   (myAssemblyName, AssemblyBuilderAccess.Run);
// Create a dynamic module in the assembly.
myModuleBuilder = myAssemblyBuilder.DefineDynamicModule("TempModule", true);
FieldInfo myFieldInfo2 =
   myModuleBuilder.DefineUninitializedData("myField", 2, FieldAttributes.Public);
// Create a type in the module.
TypeBuilder myTypeBuilder = myModuleBuilder.DefineType("TempClass",TypeAttributes.Public);
FieldBuilder myGreetingField = myTypeBuilder.DefineField("Greeting", 
   typeof(String), FieldAttributes.Public);
Type[] myConstructorArgs = { typeof(String) };
// Define a constructor of the dynamic class.
ConstructorBuilder myConstructor = myTypeBuilder.DefineConstructor(
   MethodAttributes.Public, CallingConventions.Standard, myConstructorArgs);
// Set the method implementation flags for the constructor.
myConstructor.SetImplementationFlags(MethodImplAttributes.PreserveSig | MethodImplAttributes.Runtime);
// Get the method implementation flags for the constructor.
MethodImplAttributes myMethodAttributes = myConstructor.GetMethodImplementationFlags();
Type myAttributeType = typeof(MethodImplAttributes);
int myAttribValue = (int) myMethodAttributes;
if(! myAttributeType.IsEnum)
   Console.WriteLine("This is not an Enum");
// Display the field info names of the retrieved method implementation flags.
FieldInfo[] myFieldInfo = myAttributeType.GetFields(BindingFlags.Public | BindingFlags.Static);
Console.WriteLine("The Field info names of the MethodImplAttributes for the constructor are:");
for (int i = 0; i < myFieldInfo.Length; i++)
   int myFieldValue = (Int32)myFieldInfo[i].GetValue(null);
   if ((myFieldValue & myAttribValue) == myFieldValue)
      Console.WriteLine("   " + myFieldInfo[i].Name);
