Is it possible to create an instance of a class under one button and use it in another button.

So is there any way to do so. I dont think its a good idea to create instance of a class globally because whole thing is that i want to make use of register button n so on.

how to store it as field

public class MyForm : Form
{
    // This is the field. It is "private" (cannot be seen outside this instance
    // of the class. It is of type "MyObject" (You'll want to put your own class
    // name in here). And it is called "someObject" (so you can refer to it in
    // other code in the class.)
    private MyObject someObject;

Make the variable "tmparray" private to the class like this

declare the property in the base class and then use the "new" keyword in the sub class on the same property.
