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;

如果事先要在标签中输入文本，则可以这样做。

对于设计师来说， 右键单击标签并单击属性。 在“属性”中搜索文本选项卡。 单击选项卡，然后单击旁边的箭头按钮。 上面会弹出一个对话框。 您可以在弹出框中按enter键添加行和在记事本中键入! (按enter键，你想包装标签文本)

设置AutoEllipsis属性为“TRUE”，AutoSize属性为“FALSE”。

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);

这帮助了我的表格InpitWindow: 标签设计师:

AutoSize = true;
Achors = Top, Left, Right.

private void InputWindow_Shown(object sender, EventArgs e) {
    lbCaption.MaximumSize = new Size(this.ClientSize.Width - btOK.Width - btOK.Margin.Left - btOK.Margin.Right -
        lbCaption.Margin.Right - lbCaption.Margin.Left, 
        Screen.GetWorkingArea(this).Height / 2);
    this.Height = this.Height + (lbCaption.Height - btOK.Height - btCancel.Height);
    //Uncomment this line to prevent form height chage to values lower than initial height
    //this.MinimumSize = new Size(this.MinimumSize.Width, this.Height);
}
//Use this handler if you want your label change it size according to form clientsize.
private void InputWindow_ClientSizeChanged(object sender, EventArgs e) {
    lbCaption.MaximumSize = new Size(this.ClientSize.Width - btOK.Width - btOK.Margin.Left * 2 - btOK.Margin.Right * 2 -
        lbCaption.Margin.Right * 2 - lbCaption.Margin.Left * 2,
        Screen.GetWorkingArea(this).Height / 2);
}
