本人试过，下载一个WeifenLuo.WinFormsUI.Docking.dll

使用方法可以百度一下：“WeifenLuo.WinFormsUI.Docking控件”

你可以试下。

引用DLL

private void Form1_Load(object sender, EventArgs e)

{

Form2 form2 = new Form2();

Form3 form3 = new Form3();

Form4 form4 = new Form4();

Form5 form5 = new Form5();

Form6 form6 = new Form6();

form2.Show(this.dockPanel1);

form3.Show(this.dockPanel1);

form4.Show(this.dockPanel1);

form5.Show(this.dockPanel1);

form6.Show(this.dockPanel1);

form3.DockTo(this.dockPanel1, DockStyle.Fill);

form3.DockTo(this.dockPanel1, DockStyle.Left);

form4.DockTo(this.dockPanel1, DockStyle.Bottom);

form5.DockTo(this.dockPanel1, DockStyle.Right);

form6.DockTo(this.dockPanel1, DockStyle.Right);

}

希望对您有一点点帮助。
