AutoSizeMode

字段

GrowAndShrink 0

控件根据它的内容增大或缩小。The control grows or shrinks to fit its contents. 不能手动调整该控件的大小。The control cannot be resized manually.

GrowOnly 1

控件可以根据其内容任意增大,但不会缩小至小于它的 Size 属性值。The control grows as much as necessary to fit its contents but does not shrink smaller than the value of its Size property. 窗体可以调整大小,但不能缩小到它所包含的任意控件被隐藏。The form can be resized, but cannot be made so small that any of its contained controls are hidden.

示例

下面的代码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 code example shows a form created using code that automatically resizes to fit its contents. 运行时, 窗体将显示Label TextBox , 用于输入 url, 以及Button用于在用户的默认 Web 浏览器中显示该 url。When ran, the form will display a Label, a TextBox for entering a URL, and a Button for displaying that URL inside of the user's default Web browser. 此代码示例使用FlowLayoutPanel将包含的控件逐个布局, 并AutoSize将和AutoSizeMode设置为根据其窗体的内容来放大和缩小。The code example uses a FlowLayoutPanel to lay out the contained controls one after the other, and 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;
    flowPanel.Controls.Add(urlLabel);

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

    urlButton = new Button();
    urlButton.Name = "urlButton";
    urlButton.Text = "Open URL in Browser";
    urlButton.Click += new EventHandler(urlButton_Click);
    flowPanel.Controls.Add(urlButton);
}

void urlButton_Click(object sender, EventArgs e)
{
    try
    {
        Uri newUri = new Uri(urlTextBox.Text);
    }
    catch (UriFormatException uriEx)
    {
        MessageBox.Show("Sorry, your URL is malformed. Try again. Error: " + uriEx.Message);
        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);
}
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

    urlTextBox.ForeColor = Color.Black
    Process.Start(urlTextBox.Text)
End Sub

注解

设置 GrowAndShrink 值将生成与启用了AutoSize属性但没有的控件相同的行为Setting the GrowAndShrink value produces the same behavior that you get for controls with the AutoSize property enabled but which have no

AutoSizeMode 属性。AutoSizeMode property. 考虑MinimumSizeMaximumSize和属性, 但忽略了Size属性的当前值。The MinimumSize and MaximumSize properties are respected, but the current value of the Size property is ignored.
