此讨论 [

This discussion [^]on DaniWeb may be useful. It boils down to this.

public void Open_Form(string formname)
{

    Type type = Type.GetType("myProject.Forms." + formname);
    object obj = Activator.CreateInstance(type);
    (obj as Form).MdiParent = this;
    (obj as Form).Show();

}

为此，您必须使用.Net的反射

您需要做的第一件事是在您的应用程序中的某个位置保留一组打开的表单，以供您执行查找操作.
然后，您可以简单地遍历集合，检查名称...

The first thing you need to do is to keep a collection of open forms somewhere in your application that you can perform the lookup against.
Then you can simply iterate over the collection checking the name...

public Form GetForm(string name)
{
    Form result = null;
    foreach(Form form in formsCollection)
    {
        if(form.Name == name)
        {
            result = form;
            break;
        }
    }
    return result;
}
