C# 面板作为 MDI 容器

Question

在 C# 中，我想创建一个具有 MDI 容器属性的面板，即。 isMdiContainer = true。

我试过这样的东西

form.MDIParent = this.panel1;

但这行不通。有什么建议吗？

可以创建一个 MDI 面板并在该面板中显示表单，类似下面的代码就可以完成这项工作

Mdi-Panel 定义:

public class MdiClientPanel : Panel
{
    private Form mdiForm;
    private MdiClient ctlClient = new MdiClient();

    public MdiClientPanel()
    {
        base.Controls.Add(this.ctlClient);
    }

    public Form MdiForm
    {
        get
        {
            if (this.mdiForm == null)
            {
                this.mdiForm = new Form();
                /// set the hidden ctlClient field which is used to determine if the form is an MDI form
                System.Reflection.FieldInfo field = typeof(Form).GetField("ctlClient", System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Instance);
                field.SetValue(this.mdiForm, this.ctlClient);
            }
            return this.mdiForm;
        }
    }
}

用法:

/// mdiChildForm is the form that should be showed in the panel
/// mdiClientPanel is an instance of the MdiClientPanel
myMdiChildForm.MdiParent = mdiClientPanel1.MdiForm;
