示例

下面的代码示例演示如何使用FileDialogCustomPlacesCollectionThe following code example demonstrates how to use the FileDialogCustomPlacesCollection. 若要运行此示例, 请将以下代码粘贴到 Windows 窗体InitializeDialogAndButton中, 并从窗体Load的构造函数或事件处理方法调用。To run this example, paste the following code into a Windows Form and call InitializeDialogAndButton from the form's constructor or Load event-handling method.

private OpenFileDialog openFileDialog1;
private Button button1;

private void InitializeDialogAndButton()
{
    this.openFileDialog1 = new System.Windows.Forms.OpenFileDialog();
    this.button1 = new System.Windows.Forms.Button();
    this.button1.Location = new System.Drawing.Point(53, 37);
    this.button1.AutoSize = true;
    this.button1.Text = "Show dialog with custom places.";
    this.button1.UseVisualStyleBackColor = true;
    this.button1.Click += new System.EventHandler(this.button1_Click);
    this.Controls.Add(this.button1);
}

private void button1_Click(object sender, EventArgs e)
{
    // Add Pictures custom place using GUID.
    openFileDialog1.CustomPlaces.Add("33E28130-4E1E-4676-835A-98395C3BC3BB");

    // Add Links custom place using GUID
    openFileDialog1.CustomPlaces.Add(
        new FileDialogCustomPlace(
        new Guid("BFB9D5E0-C6A9-404C-B2B2-AE6DB6AF4968")));

    // Add Windows custom place using file path.
    openFileDialog1.CustomPlaces.Add(@"c:\Windows");

    openFileDialog1.ShowDialog();
}
