1、 C#窗体间的数据传值(使用静态类) 收藏之前使用带参数的构造函数、属性以及方法实现了数据的交互，接下来的是使用静态类来完成窗体间的数据交互。这也是经常要用到的一种数据交互方法。下面是定义的一个类：using System;using System.Collections;namespace ZZpublic class AppDatas/静态数据成员private static ArrayList listData;/静态构造函数static AppDatas()listData = new ArrayList();listData.Add(DotNet);listData.Add(C#);
2、listData.Add(A);listData.Add(WebService);listData.Add(XML);/静态属性public static ArrayList ListDatagetreturn listData;/静态方法public static ArrayList GetListData()return listData;上面包含了一个静态类成员，listData,一个静态构造函数 static AppDatas()，用来初始化 listData 的数据。还有一个静态属性 ListData 和一个静态 GetListData()方法，他们实现了同样的功能就是返回 list
