问过多次了(不气馁),如何做到多个窗体使用一个公用的全局变量啊?
一个全局的int,string,Web Services的引用变量
如何使上面的三个冬冬,能在所有的窗体中都可以访问啊?

搂住可能被自己给误导了
class Form1{..}
class Form2{..}
class Form3{..}
class ArrageForms{ Form1 form1;
Form2 form2;

Var var;}

用公共类
public class SysInfo
{
public static string solution ="";
public static string project ="";
public static string id ="";
public static string title ="";
public static string schemefile ="";
public static bool brefresh=false;
public static ArrayList schemelist =new ArrayList();
public static int listindex=0;
