Invokes the current constructor with the specified arguments.

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

Syntax

'Declaration
<DebuggerHiddenAttribute> _
<DebuggerStepThroughAttribute> _
Public Function Invoke ( _
    parameters As Object() _
) As Object

[DebuggerHiddenAttribute]
[DebuggerStepThroughAttribute]
public Object Invoke(
    Object[] parameters
)

Parameters

parameters
Type: array<System.Object[]
An array of values that matches the number, order, and type (under the constraints of the default binder) of the parameters for this constructor. If this constructor takes no parameters, pass nulla null reference (Nothing in Visual Basic) or an array with zero elements; for example, new Object[] {} (New Object() {} in Visual Basic). Any object in this array that is not explicitly initialized with a value will contain the default value for that object type. For reference-type elements, this value is nulla null reference (Nothing in Visual Basic). For value-type elements, this value is 0, 0.0, or false, depending on the specific element type.

Return Value

Type: System.Object
An instance of the class that is associated with the constructor.

Exceptions

Exception	Condition
MemberAccessException	The class is abstract. -or- The constructor is a class initializer.
MethodAccessException	The constructor is private or protected.
ArgumentException	The parameters array does not contain values that match the types accepted by this constructor.
TargetInvocationException	The invoked constructor throws an exception.
TargetParameterCountException	An incorrect number of parameters was passed.
NotSupportedException	Creation of TypedReference and RuntimeArgumentHandle types is not supported.

Remarks

In Silverlight, you can invoke only accessible constructors.

The number, type, and order of elements in the parameters array must match the number, type, and order of parameters for the constructor reflected by this instance, as determined by the default binder.

Platform Notes

Silverlight for Windows Phone

Invoke throws an ArgumentException exception instead of a TargetParameterCountException exception when there is a mismatch in the number of arguments.
