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

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

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

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

Syntax

'Declaration
<SecuritySafeCriticalAttribute> _
<ComVisibleAttribute(True)> _
Public Function DefineConstructor ( _
    attributes As MethodAttributes, _
    callingConvention As CallingConventions, _
    parameterTypes As Type(), _
    requiredCustomModifiers As Type()(), _
    optionalCustomModifiers As Type()() _
) As ConstructorBuilder

[SecuritySafeCriticalAttribute]
[ComVisibleAttribute(true)]
public ConstructorBuilder DefineConstructor(
    MethodAttributes attributes,
    CallingConventions callingConvention,
    Type[] parameterTypes,
    Type[][] requiredCustomModifiers,
    Type[][] optionalCustomModifiers
)

Parameters

attributes
Type: System.Reflection.MethodAttributes
The attributes of the constructor.

callingConvention
Type: System.Reflection.CallingConventions
The calling convention of the constructor.

parameterTypes
Type: array<System.Type[]
The parameter types of the constructor.

requiredCustomModifiers
Type: array<array<System.Type[][]
An array of arrays of types. Each array of types represents the required custom modifiers for the corresponding parameter, such as IsConst. If a particular parameter has no required custom modifiers, specify nulla null reference (Nothing in Visual Basic) instead of an array of types. If none of the parameters have required custom modifiers, specify nulla null reference (Nothing in Visual Basic) instead of an array of arrays.

optionalCustomModifiers
Type: array<array<System.Type[][]
An array of arrays of types. Each array of types represents the optional custom modifiers for the corresponding parameter, such as IsConst. If a particular parameter has no optional custom modifiers, specify nulla null reference (Nothing in Visual Basic) instead of an array of types. If none of the parameters have optional custom modifiers, specify nulla null reference (Nothing in Visual Basic) instead of an array of arrays.

Return Value

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

Exceptions

Exception	Condition
ArgumentException	The size of requiredCustomModifiers or optionalCustomModifiers does not equal the size of parameterTypes.
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.

ArgumentException

The size of requiredCustomModifiers or optionalCustomModifiers does not equal the size of parameterTypes.

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

This overload is provided for designers of managed compilers.
