如何在 C# 中设置 GroupBox 的自动大小模式？

第 3 步：最后将此 GroupBox 控件添加到表单中，并使用以下语句在 GroupBox 上添加其他控件：// Adding groupbox in the form

this.Controls.Add(gbox);

and

// Adding this control

// to the GroupBox

gbox.Controls.Add(c2);

例子：

using System;

using System.Collections.Generic;

using System.ComponentModel;

using System.Data;

using System.Drawing;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

using System.Windows.Forms;

namespace WindowsFormsApp46 {

public partial class Form1 : Form {

public Form1()

{

InitializeComponent();

}

private void Form1_Load(object sender, EventArgs e)

{

// Creating and setting

// properties of the GroupBox

GroupBox gbox = new GroupBox();

gbox.Location = new Point(179, 145);

gbox.Text = "Select Gender";

gbox.Name = "Mybox";

gbox.Font = new Font("Colonna MT", 12);

gbox.Visible = true;

gbox.AutoSize = true;

gbox.AutoSizeMode = AutoSizeMode.GrowAndShrink;

// Adding groupbox in the form

this.Controls.Add(gbox);

// Creating and setting

// properties of the CheckBox

CheckBox c1 = new CheckBox();

c1.Location = new Point(40, 42);

c1.Size = new Size(69, 20);

c1.Text = "Male";

// Adding this control

// to the GroupBox

gbox.Controls.Add(c1);

// Creating and setting

// properties of the CheckBox

CheckBox c2 = new CheckBox();

c2.Location = new Point(183, 39);

c2.Size = new Size(79, 20);

c2.Text = "Female";

// Adding this control

// to the GroupBox

gbox.Controls.Add(c2);

}

}

}

输出：
