我试图创建一个自定义窗体设计器与这篇文章： http://www.developerfusion.com/article/4351/hosting-windows-forms-designers/ ，让您创建自定义窗体，视觉工作室一样。但我不知道如何获得创建的窗体中的所有控件，有人知道如何做到这一点？从c托管windows窗体设计器获取项目＃

这里是我的尝试：

 // And then i tried this to get all the controls and write them to a python tkinter file: 
     private void menuItem2_Click(object sender, EventArgs e) 
     { 
      System.IO.StreamWriter sw = new System.IO.StreamWriter("output.py"); 
      sw.WriteLine("from tkinter import *\n"); 
      sw.WriteLine("# Main form"); 
      sw.WriteLine(this.Name + " = Tk()\n"); 
      foreach (IComponent b in components.Components) 
      { 
       MessageBox.Show(b.GetType().ToString()); 
       if (b.GetType() == typeof(Button)) 
       { 
        Button but = (Button)b; 
        sw.WriteLine("# " + but.Name); 
        sw.WriteLine(but.Name + " = Button(" + this.Name + @"fg=""" + but.ForeColor.Name + @"""bg=""" + but.BackColor.Name + @"""" + ")"); 
       } 
      } 
      sw.Close(); 
     }

在此先感谢。

'FormInstance.Controls'？此外，如果您的文章成为死链接会发生什么？写一个简短的总结，以便我们知道它的含义。 – Transcendental

不，这不起作用... – Daniel

你到底想做什么？这应该给你所有的控件的第一个父对象是FormInstance。 – Transcendental

您可以通过循环使用添加控件。

Foreach(Control c in form.Controls) 
{ 
    //You can save all attribute for each control on file or database 
    //c.Left, c.Top, c.Name,... 
}

当你重装控制形成，通过代码中使用：

TextBox textbox = (TextBox)host.CreateComponent(typeof(TextBox)); 
textbox.Left = your value save before; 
textbox.Top = your value save before; 
textbox.Text = your text save before; 
form.Controls.Add(textbox);

..Similar为orther控制

请在语法上多加一些努力，很难理解你在写什么。 –
