示例

下面的示例演示使用自动调整大小以适合其内容的代码创建的窗体。The following example shows a form created using code that automatically resizes to fit its contents. 运行时,该窗体将显示一个 Label、一个用于输入 URL 的 TextBox 和一个 Button,用于在用户的默认 Web 浏览器中显示该 URL。When run, the form displays a Label, a TextBox for entering a URL, and a Button for displaying that URL inside of the user's default Web browser. 该示例使用 FlowLayoutPanel 将包含的控件逐个布局。The example uses a FlowLayoutPanel to lay out the contained controls one after the other. 它还会将 @no__t 设置为-1,AutoSizeMode,以适应其窗体的内容。It also sets the AutoSize and AutoSizeMode to grow and shrink to fit the contents of its form.

private void Form1_Load(object sender, EventArgs e)
{
    this.AutoSize = true;
    this.AutoSizeMode = AutoSizeMode.GrowAndShrink;
    this.Text = "URL Opener";

    flowPanel = new FlowLayoutPanel();
    flowPanel.AutoSize = true;
    flowPanel.AutoSizeMode = AutoSizeMode.GrowAndShrink;
    this.Controls.Add(flowPanel);

    urlLabel = new Label();
    urlLabel.Name = "urlLabel";
    urlLabel.Text = "URL:";
    urlLabel.Width = 50;
    urlLabel.TextAlign = ContentAlignment.MiddleCenter;

    urlTextBox = new TextBox();
    urlTextBox.Name = "urlTextBox";
    urlTextBox.Width = 250;

        urlTextBox.ForeColor = Color.Red;
        return;
    }
    
    // Valid URI. Reset any previous error color, and launch the URL in the 
    // default browser.
    // NOTE: Depending on the user's settings, this method of starting the
    // browser may use an existing window in an existing Web browser process.
    // To get around this, start up a specific browser instance instead using one of
    // the overloads for Process.Start. You can examine the registry to find the
    // current default browser and launch that, or hard-code a specific browser.
    urlTextBox.ForeColor = Color.Black;
    Process.Start(urlTextBox.Text);

注解

如果将 @no__t 值设置为新值,则会再次布局该窗体。Setting the AutoSizeMode property to a new value causes the form to be laid out again.

窗体不会在 Visual Studio 窗体设计器中自动调整大小,而不管 AutoSize 和 @no__t 属性的值。A form does not automatically resize in the Visual Studio forms designer, regardless of the values of the AutoSize and AutoSizeMode properties. 窗体根据这两个属性的值在运行时正确地调整大小。The form correctly resizes itself at run time according to the values of these two properties. 与此相反,自定义 UserControl 会在设计时和运行时自动调整自身的大小。By contrast, a custom UserControl automatically resizes itself both at design time and at run time.
