使用System.Windows.Forms.LinkLabel代替Label，并设置属性LinkArea如下所示。

myLabel.LinkArea = new LinkArea(0, 0);

如果需要保持按钮尺寸不变:

myButton.Text = "word\r\nwrapped"

我有一个标签，自动包装和增长到任何大小在右停靠的自动大小面板，其宽度是由其他内容设置。

标签(在tablelayoutpanel) Autosize = True。

tableelayoutpanel(在面板)Autosize = True, AutoSizeMode = GrowAndShrink, Dock =底部，一列SizeType = 100%，一行SizeType = 100%。

面板(右停靠形式)AutoSize = True, AutoSizeMode = GrowAndShrink, Dock =右。

把标签放在面板里 处理面板的ClientSizeChanged事件，使 标签填充空间: Panel2_ClientSizeChanged(对象发送器，EventArgs e) ｛ label1。MaximumSize =新大小((发送方作为控件). clientsize . Size。宽度- label1。离开,10000); ｝ 将标签的自动大小设置为true 将标签“Dock”设置为“Fill”

除了第2步，其他步骤通常都在设计器窗口中完成。

If your panel is limiting the width of your label, you can set your label’s Anchor property to Left, Right and set AutoSize to true. This is conceptually similar to listening for the Panel’s SizeChanged event and updating the label’s MaximumSize to a new Size(((Control)sender).Size.Width, 0) as suggested by a previous answer. Every side listed in the Anchor property is, well, anchored to the containing Control’s respective inner side. So listing two opposite sides in Anchor effectively sets the control’s dimension. Anchoring to Left and Right sets the Control’s Width property and Anchoring to Top and Bottom would set its Height property.

这个解决方案，作为c#:

label.Anchor = AnchorStyles.Left | AnchorStyles.Right;
label.AutoSize = true;

在标签中使用style="overflow:Scroll"，如下面的HTML。这将在面板内的标签中添加滚动条。

<asp:Label
    ID="txtAOI"
    runat="server"
    style="overflow:Scroll"
    CssClass="areatext"
    BackColor="White"
    BorderColor="Gray"
    BorderWidth="1"
    Width = "900" ></asp:Label>
