从一个控件传递到另一个类变量的值？

Question

I have one textbox1 in form1, I have another class called ClassDemo() , this class does not have a form. I have one method in this class, called HelloWorld() inside hello world I have one string val variable.

I want to pass the textbox1 value to ClassDemo's variable when the HelloWorld(), method is called.

How can I do that?

Answer 1

You can try multiple ways here.

1. Make the method as parameterized method. Put a string parameter inside the method declaration and then whenever you call that method, pass that string value that you want to pass.
2. Store the string value in global variable or Session(only if needed). This wasy, your value can flow across the application and can be accessed in any area wherever its needed.
3. Pass by Value or Pass by reference. You can opt for either one in C# to pass variables/values across connected areas.

Hope this clears the idea.
