[SOLVED] How to initialize a generic class in an external package

How to initialize a generic class in an external package

I am trying to initialize a generic class with an object type, however am unable to do it.

Below code will explain what I mean:

PagingList<MyForm> Form = new  PagingList<MyForm>();

So PagingList is my generic class and I have assigned the type "MyForm", however am unable to initialize it.

The error is :

"PagingList' does not contain a constructor that takes 0 arguments"

PagingList is a package which I added externally. MyForm is a class which I have created.

How could I initialize this?

Thank you.

Solution

To create an instance of the class you need to call a constructor of this class like you do:

new PagingList<MyForm>();

You try to call the default constructor that takes no arguments.

The error you see means that there is no constructor in PagingList class that takes 0 arguments. Check in the object browser if there are other constructors with 1 or more parameters or static methods that instantiates this class.

If you want you can refer to the documentation for more details on constructors: C# Classes Constructors
