if the forms are in the same session you can put the variables into
session state variables.
Session["var1"] = davar ; // to set the variable.
davar = (type) Session["var1"] ; // to read the variable.
If they are different sessions you can put them in
the command that calls the other form. You will need
to pass them as strings.
response.redirect("form1?var1=daval");
and you read the variable like this:
davar = Request.QueryString["var1"];
See if you can use these.

Hello,
I think you are not talking about a web application , so The only way to see the varaibles of a class in another one without making an object is using static key word, so you can access that variable from the class name:
Example:
class One
{
public static string variable;
}
class Two
{
void main()
{
MessageBox.Show(One.variable);
}
}
