Create a public class and declare a public static variable in it, see demo code inside.

sellcar_2003_may(sellcar_2003_may)

Method 1.

Step 1, create a public class and a public static variable in the class. Which is tableName .

using System;

namespace global
{
public class global_class
{
public static string tableName="Demo";
public global_class()
{
//
// TODO: Add constructor logic here
//
}
}
}

In other winform/class files, call the variable like below:

global_class.tableName

You don't even need to create an instance of the "global_class" class.

Method 2,
If you are developing ASP.Net, you can put the global variables inside web.config file.

Happy programming...

工作学习 / IT技术讨论 / help:在C# 有没有全局数据变量的概念? 我希望在各个窗体中都能使用到公共的全局变量,就好比在VB 里使用MODULE 一样,定义一个PUBLIC 的变量,那么在各个窗体中都能使用到? -bobo123(bobo); 2004-11-8 (#1971243@0)

One way is to create a base form which has public static variables, then all your forms are derived from your base form instead of Windows Form. HTH, Victor -ggwd(Victor); 2004-11-9 (#1973509@0)

I don't think that is a solution. -guestagain(guest again); 2004-11-9 (#1973518@0)

global variable -- can be accessed by all applications on the server; application variable -- can be accessed by all forms in the application; session variable -- can be accessed by all pages in one session. -orange0(桔子); 2004-11-10 (#1973673@0)

do not use namespace, the class which is defined as public will be global. Of course, you can declare varables in the class. Variables in the class are global as well. -hkxwz(HKXWZ); 2004-11-13 (#1980309@0)
