Type.GetConstructor Method (Type[])

 

Searches for a public instance constructor whose parameters match the types in the specified array.

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

[<ComVisibleAttribute(true)>]
abstract GetConstructor : 
        types:Type[] -> ConstructorInfo
[<ComVisibleAttribute(true)>]
override GetConstructor : 
        types:Type[] -> ConstructorInfo

Parameters

types
Type: System.Type[]

An array of Type objects representing the number, order, and type of the parameters for the desired constructor.

-or-

An empty array of Type objects, to get a constructor that takes no parameters. Such an empty array is provided by the static field Type.EmptyTypes.

Return Value

Type: System.Reflection.ConstructorInfo

An object representing the public instance constructor whose parameters match the types in the parameter type array, if found; otherwise, null.

Exception Condition
ArgumentNullException

types is null.

-or-

One of the elements in types is null.

ArgumentException

types is multidimensional.

This method overload looks for public instance constructors and cannot be used to obtain a class initializer (.cctor). To get a class initializer, use an overload that takes BindingFlags, and specify BindingFlags.Static | BindingFlags.NonPublic (BindingFlags.StaticOrBindingFlags.NonPublic in Visual Basic). You can also get the class initializer using the TypeInitializer property.

If the requested constructor is non-public, this method returns null.

System_CAPS_noteNote

You cannot omit parameters when looking up constructors and methods. You can only omit parameters when invoking.

If the current Type represents a constructed generic type, this method returns the ConstructorInfo with the type parameters replaced by the appropriate type arguments. If the current Type represents a type parameter in the definition of a generic type or generic method, this method always returns null.

The following example obtains the type of MyClass, gets the ConstructorInfo object, and displays the constructor signature.
