Examples

The following code sample demonstrates how to attach a dynamic method to a set property created with PropertyBuilder using SetSetMethod.

// Define a public class named "HelloWorld" in the assembly.
TypeBuilder helloWorldTypeBuilder = myModule.DefineType("HelloWorld", TypeAttributes.Public);
// Define a private String field named "m_greeting" in "HelloWorld" class.
FieldBuilder greetingFieldBuilder = helloWorldTypeBuilder.DefineField("m_greeting",
                                          typeof(String), FieldAttributes.Private);
// Create constructor args and define constructor.
Type[] constructorArgs = { typeof(String) };
ConstructorBuilder constructor = helloWorldTypeBuilder.DefineConstructor(
   MethodAttributes.Public, CallingConventions.Standard, constructorArgs);

// Generate IL code for the method. The constructor stores its argument in the private field.
ILGenerator constructorIL = constructor.GetILGenerator();
constructorIL.Emit(OpCodes.Ldarg_0);
constructorIL.Emit(OpCodes.Ldarg_1);
constructorIL.Emit(OpCodes.Stfld, greetingFieldBuilder);
constructorIL.Emit(OpCodes.Ret);
// Define property Greeting.
PropertyBuilder greetingPropertyBuilder = helloWorldTypeBuilder.DefineProperty(
                         "Greeting",PropertyAttributes.None,typeof(string),null);

// Define the 'get_Greeting' method.
MethodBuilder getGreetingMethod = helloWorldTypeBuilder.DefineMethod("get_Greeting",
   MethodAttributes.Public|MethodAttributes.HideBySig|MethodAttributes.SpecialName,
   typeof(String),null);
// Generate IL code for 'get_Greeting' method.
ILGenerator methodIL = getGreetingMethod.GetILGenerator();
methodIL.Emit(OpCodes.Ldarg_0);
methodIL.Emit(OpCodes.Ldfld, greetingFieldBuilder);
methodIL.Emit(OpCodes.Ret);
greetingPropertyBuilder.SetGetMethod(getGreetingMethod);

// Define the set_Greeting method.
Type[] methodArgs = {typeof(string)};
MethodBuilder setGreetingMethod = helloWorldTypeBuilder.DefineMethod("set_Greeting",
   MethodAttributes.Public|MethodAttributes.HideBySig|MethodAttributes.SpecialName,
   typeof(void), methodArgs);
// Generate IL code for set_Greeting method.
methodIL = setGreetingMethod.GetILGenerator();
methodIL.Emit(OpCodes.Ldarg_0);
methodIL.Emit(OpCodes.Ldarg_1);
methodIL.Emit(OpCodes.Stfld,greetingFieldBuilder);
methodIL.Emit(OpCodes.Ret);
greetingPropertyBuilder.SetSetMethod(setGreetingMethod);
