プロパティ値

フォームのサイズが自動的に変更される場合は true。手動でサイズを変更する必要がある場合は falsetrue if the form will automatically resize; false if it must be manually resized.

次のコード例では、その内容に合わせて自動的にサイズを変更するコードを使用して作成されたフォームを示します。The following code example shows a form created using code that automatically resizes to fit its contents. 実行すると、フォームが表示されます、 LabelTextBox 、URL を入力するため、Buttonユーザーの既定の Web ブラウザー内でその URL を表示するためです。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. コード例では、FlowLayoutPanel格納されているをレイアウトするには、1 つずつを制御します。The code example uses a FlowLayoutPanel to lay out the contained controls one after the other. また、設定、AutoSizeAutoSizeMode拡大は、フォームの内容に合わせて縮小します。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.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);

        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);

注釈

使用AutoSize内容に合わせてサイズを変更するためのフォームを強制的にします。Use AutoSize to force a form to resize to fit its contents.

フォームがの値に関係なく、Visual Studio のフォーム デザイナーで自動的にサイズ変更されない、AutoSizeAutoSizeModeプロパティ。A form does not automatically resize in the Visual Studio forms designer, regardless of the values of the AutoSize and AutoSizeMode properties. フォームでは、これら 2 つのプロパティの値に基づいて実行時に自体正しく変更します。The form correctly resizes itself at run time according to the values of these two properties. 一方、カスタムUserControl自体デザイン時と実行時の両方で自動的にサイズ変更します。By contrast, a custom UserControl automatically resizes itself both at design time and at run time.

使用する場合AutoSizeMinimumSizeMaximumSizeの現在の値が、プロパティが尊重、Sizeプロパティは無視されます。When using AutoSize, the MinimumSize and MaximumSize properties are respected, but the current value of the Size property is ignored. 使用してAutoSizeAutoSizeModeもレンダリング、AutoScrollプロパティ余分なようにビューからその格納されているコントロールを非表示にするためのフォームを縮小する方法はありません。Using AutoSize and AutoSizeMode also renders the AutoScroll property superfluous, as there is no way to shrink the form to hide its contained controls from view.

参照してください、AutoSizeModeフォームによる場合の動作方法については、列挙体AutoSizetrueします。See the AutoSizeMode enumeration for information on how a form behaves when AutoSize is true.
