大致效果看起来如下

1、大致效果看起来如下点击浏览按钮，会弹出一个对话框，让我们选择一个文件夹选择某个文件夹之后，点击“确定”，此时会把该目录下面的图片文件读取出来一个列表。如下面所示 那么大致是怎么实现的呢？首先，让我们的那个类型继承System.Windows.Forms.UserControl类型其次，在这个UserControl上面设计一些子控件我们在拖拽控件的时候，设计器会帮助生成一个方法：InitializeComponent，类似下面这样 private void InitializeComponent() ponents = new System.ComponentModel.Contain

2、er(); this.listView1 = new System.Windows.Forms.ListView(); this.imageList1 = new System.Windows.Forms.ImageList(ponents); this.btBrowser = new System.Windows.Forms.Button(); this.btUpload = new System.Windows.Forms.Button(); this.SuspendLayout(); / / listView1 / this.listView1.Anchor = (System.Wind

3、ows.Forms.AnchorStyles)(System.Windows.Forms.AnchorStyles.Top | System.Windows.Forms.AnchorStyles.Bottom) | System.Windows.Forms.AnchorStyles.Left) | System.Windows.Forms.AnchorStyles.Right); this.listView1.LargeImageList = this.imageList1; this.listView1.Location = new System.Drawing.Point(8, 5); t

4、his.listView1.Name = "listView1" this.listView1.Size = new System.Drawing.Size(790, 195); this.listView1.TabIndex = 0; this.listView1.UseCompatibleStateImageBehavior = false; / / imageList1 / this.imageList1.ColorDepth = System.Windows.Forms.ColorDepth.Depth8Bit; this.imageList1.ImageSize

5、= new System.Drawing.Size(64, 64); this.imageList1.TransparentColor = System.Drawing.Color.Transparent; / / btBrowser / this.btBrowser.Anchor = (System.Windows.Forms.AnchorStyles)(System.Windows.Forms.AnchorStyles.Bottom | System.Windows.Forms.AnchorStyles.Left); this.btBrowser.Location = new System

6、.Drawing.Point(5, 206); this.btBrowser.Name = "btBrowser" this.btBrowser.Size = new System.Drawing.Size(76, 23); this.btBrowser.TabIndex = 1; this.btBrowser.Text = "浏览." this.btBrowser.UseVisualStyleBackColor = true; this.btBrowser.Click += new System.EventHandler(this.btBrowser_

7、Click); / / btUpload / this.btUpload.Anchor = (System.Windows.Forms.AnchorStyles)(System.Windows.Forms.AnchorStyles.Bottom | System.Windows.Forms.AnchorStyles.Left); this.btUpload.Location = new System.Drawing.Point(86, 206); this.btUpload.Name = "btUpload" this.btUpload.Size = new System.

8、Drawing.Size(75, 23); this.btUpload.TabIndex = 2; this.btUpload.Text = "上传." this.btUpload.UseVisualStyleBackColor = true; / / MyActiveXControl / this.BackColor = System.Drawing.Color.White; this.BorderStyle = System.Windows.Forms.BorderStyle.FixedSingle; this.Controls.Add(this.btUpload);

9、this.Controls.Add(this.btBrowser); this.Controls.Add(this.listView1); this.Name = "MyActiveXControl" this.Padding = new System.Windows.Forms.Padding(5); this.Size = new System.Drawing.Size(806, 237); this.ResumeLayout(false); 接下来编写代码，与windows Forms里面编程没有任何区别。为按钮绑定事件处理程序等等这里要注意的是，需要手工地添加一个构

10、造函数，在构造函数中调用InitializeComponent public MyActiveXControl() InitializeComponent(); 至于选择文件夹的代码，大致如下 private void btBrowser_Click(object sender, EventArgs e) FolderBrowserDialog dialog = new FolderBrowserDialog(); dialog.SelectedPath = Environment.GetFolderPath(Environment.SpecialFolder.MyPictures); if (dialog.ShowDialog() = DialogResult.OK) listView1.Items.Clear(); DirectoryInfo dir = new DirectoryInfo(dialog.SelectedPath); foreach (FileInfo file in dir.GetFiles("*.jpg") ListViewI
