Microsoft Silverlight will reach end of support after October 2021. Learn more.

Defines the default constructor. The constructor defined here will simply call the default constructor of the parent.

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

Syntax

'Declaration
<ComVisibleAttribute(True)> _
Public Function DefineDefaultConstructor ( _
    attributes As MethodAttributes _
) As ConstructorBuilder

[ComVisibleAttribute(true)]
public ConstructorBuilder DefineDefaultConstructor(
    MethodAttributes attributes
)

Parameters

Return Value

Type: System.Reflection.Emit.ConstructorBuilder
The defined constructor.

Exceptions

Exception Condition
NotSupportedException

The parent type (base type) does not have a default constructor.
InvalidOperationException

The type was previously created using CreateType.

-or-

For the current dynamic type, the IsGenericType property is true, but the IsGenericTypeDefinition property is false.

-or-

The current type is an interface.

Remarks

Because the default constructor is automatically defined, it is necessary to call this method only in the following situations:

  • You have defined another constructor and you also want a default constructor that simply calls the base class constructor.

  • You want to set the attributes on the default constructor to something other than PrivateScope, Public, HideBySig, SpecialName, and RTSpecialName.
