在解决方案资源管理器中查找活动winform

Question

I started working on a existing solution that has a very large number of Winforms. Is there a quick way to find the design time form, in the Visual Studio Solution Explorer, when the application is running?

Please note: debug/break will only help me find modal forms (dialogs). I am interested in finding modeless winforms too. I don't consider plowing through design time menus and events as a quick way..

Answer 1

I hope this is what you want:

With Application.OpenForms ( click )

You'll get a list of all open Forms which belongs to you project. Then you can easily find out the form in the Explorer.

Answer 2

You could also make an debug menu item on you main form and put in it :

string test = string.Empty;
foreach (Form item in Application.OpenForms)
{
    test += item.GetType().ToString() + Environment.NewLine;
} 
MessageBox.Show(test);

This will give you a list of openforms just like Markus G suggested but without the need of creating a form for this.

Also look at this :

https://msdn.microsoft.com/en-us/library/system.windows.forms.form.activeform(v=vs.110).aspx

It explains how you can identify the active form, but as usual microsoft has made things a bit complex by having 2 methods, one for mdi forms and one for none mdi forms
