TypeBuilder.DefineConstructor Method (MethodAttributes, CallingConventions, Type[])

Adds a new constructor to the type, with the given attributes and signature.

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

[ComVisibleAttribute(true)] 
public ConstructorBuilder DefineConstructor (
	MethodAttributes attributes,
	CallingConventions callingConvention,
	Type[] parameterTypes
)
/** @attribute ComVisibleAttribute(true) */ 
public ConstructorBuilder DefineConstructor (
	MethodAttributes attributes, 
	CallingConventions callingConvention, 
	Type[] parameterTypes
)
ComVisibleAttribute(true) 
public function DefineConstructor (
	attributes : MethodAttributes, 
	callingConvention : CallingConventions, 
	parameterTypes : Type[]
) : ConstructorBuilder

Parameters

attributes

The attributes of the constructor.

callingConvention

The calling convention of the constructor.

parameterTypes

The types of the parameters of the constructor.

Return Value

The defined constructor.

Exception typeCondition

InvalidOperationException

The type was previously created using CreateType.

The following code sample demonstrates the use of DefineConstructor to set a constructor's particular signature and attributes on a dynamic type and return a corresponding ConstructorBuilder for IL population.

// Define the constructor.
Type[] constructorArgs = { typeof(String) };
ConstructorBuilder myConstructorBuilder = 
   helloWorldTypeBuilder.DefineConstructor(MethodAttributes.Public, 
                      CallingConventions.Standard, constructorArgs);
// Generate IL for the method.The constructor stores its argument in the private field.
ILGenerator myConstructorIL = myConstructorBuilder.GetILGenerator();
myConstructorIL.Emit(OpCodes.Ldarg_0);
myConstructorIL.Emit(OpCodes.Ldarg_1);
myConstructorIL.Emit(OpCodes.Stfld, myGreetingField);
myConstructorIL.Emit(OpCodes.Ret);
