c# - Input from main form to another form -

i want receive input 2nd form main form.
i've tried generate method in 2nd form, that's got:

internal form2 method(string value) {     throw new notimplementedexception(); }

the value 1st form should passed "value" variable.
how return "value" string, can use it?

by way, don't know how work "internal" access modifier.

you can create 1 class

public class valuetransfer  {   public string value1{get;set;}   }

now can create object of valuetenasfer from1

valuetransfer v=new valuetransfer();  v.value1="string";

and pass class object other method
