在.net中轻松掌握Windows窗体间的数据交互(三)
zhzuo(秋枫)
在第一篇和第二篇文章中我们使用带参数的构造函数、属性以及方法实现了数据的交互,接下来要讲的是使用静态类来完成窗体间的数据交互。这个也是我们经常要用到的一种数据交互方法。
三.使用静态类
下面是定义的一个类:
using System;
using System.Collections;
namespace ZZ
{
public class AppDatas
{
private static ArrayList listData;
static AppDatas()
{
listData = new ArrayList();
listData.Add("DotNet");
listData.Add("C#");
listData.Add("Asp.net");
listData.Add("WebService");
listData.Add("XML");
}
public static ArrayList ListData
{
get{return listData;}
}
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listData。
由于前面两篇文章已经讲了很多,这里不细说了,下面是完整的代码:
Form1.cs文件
using System;
using System.Drawing;
using System.Collections;
using System.ComponentModel;
using System.Windows.Forms;
namespace ZZ
{
public class Form1 : System.Windows.Forms.Form
{
private System.Windows.Forms.Button buttonEdit;
private System.Windows.Forms.ListBox listBoxFrm1;
private System.ComponentModel.Container components = null;
public Form1()
{
InitializeComponent();
this.listBoxFrm1.DataSource = AppDatas.ListData;
}
protected override void Dispose( bool disposing )
{
if( disposing )
if(components != null)
components.Dispose();
base.Dispose( disposing );
}
[STAThread]
static void Main()
{
Application.Run(new Form1());
}
private void InitializeComponent()
{
this.buttonEdit = new System.Windows.Forms.Button();
this.listBoxFrm1 = new System.Windows.Forms.ListBox();
this.SuspendLayout();
this.buttonEdit.Location = new System.Drawing.Point(128, 108);
this.buttonEdit.Name = "buttonEdit";
this.buttonEdit.TabIndex = 1;
this.buttonEdit.Text = "修改";
this.buttonEdit.Click += new System.EventHandler(this.buttonEdit_Click);
this.listBoxFrm1.ItemHeight = 12;
this.listBoxFrm1.Location = new System.Drawing.Point(12, 8);
this.listBoxFrm1.Name = "listBoxFrm1";
this.listBoxFrm1.Size = new System.Drawing.Size(108, 124);
this.listBoxFrm1.TabIndex = 2;
this.AutoScaleBaseSize = new System.Drawing.Size(6, 14);
this.ClientSize = new System.Drawing.Size(208, 141);
this.Controls.Add(this.listBoxFrm1);
this.Controls.Add(this.buttonEdit);
this.Name = "Form1";
this.Text = "Form1";
this.ResumeLayout(false);
}
private void buttonEdit_Click(object sender, System.EventArgs
