C#中的多文档的使用

1.首先，新建一个窗体，设置窗体的IsMdiContainer = true;

窗体的大小为700*600  长700  高600

2.在窗体的Load事件中添加如下代码

  private void FormMain_Load(object sender, EventArgs e)
        {
            Form form = new Form();
            form.FormBorderStyle = FormBorderStyle.FixedToolWindow;
            form.MdiParent = this;
            form.Dock = DockStyle.Left;
            form.Width = 200;
            form.Show();

            Form form2 = new Form();
            form2.FormBorderStyle = FormBorderStyle.FixedToolWindow;
            form2.MdiParent = this;
            form2.Dock = DockStyle.Bottom;
            form2.Height = 100;
            form2.Show();

            LayoutMdi(MdiLayout.ArrangeIcons);
        }

最上层是一个菜单栏

下面是一个工具栏

最底层是一个状态栏

选中第一个子窗体

选中第二个子窗体

另外一种形式，多加了2个窗体

 private void Form1_Load(object sender, EventArgs e)
        {
            try
            {

                //在窗体的底部
                Form form2 = new Form();
                form2.FormBorderStyle = FormBorderStyle.FixedToolWindow;
                form2.MdiParent = this;
                form2.Dock = DockStyle.Bottom;
                form2.Height = 100;
                form2.Text = @"窗体2";
                form2.Show();

                Splitter splitter=new Splitter();
                splitter.Dock = DockStyle.Bottom;

                //在窗体的左侧
                Form form = new Form();
                form.FormBorderStyle = FormBorderStyle.FixedToolWindow;
                form.MdiParent = this;
                form.Dock = DockStyle.Left;
                form.Width = 200;
                form.Text = @"窗体1";
                form.Show();

                Form form3 = new Form();
                form3.MdiParent = this;
                form3.Dock = DockStyle.Fill;
                form3.Text = @"窗体3";
                form3.MaximizeBox = false;
                form3.Show();

                Form form4 = new Form();
                form4.MdiParent = this;
                form4.Dock = DockStyle.Fill;
                form4.Text = @"窗体4";
                form4.MaximizeBox = false;
                form4.Show();

                //LayoutMdi(MdiLayout.TileHorizontal);
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
        }
