向现有解决方案添加新表单 - 而不是现有表单中的类选项 [英] Adding new forms to existing solution - not a class option in existing forms

问题描述

在c＃world中迈出第一步... 

Making my first steps in c# world.. 

我已经有了Windows的现有解决方案我希望为它添加更多Windows窗体的表单。这很容易。

I've got an existing solution with Windows forms which I wanted to add few more Windows forms to it. That was the easy part.

我可以将新添加的表单添加到"查看"中彼此作为一个类并按一个按钮从另一个表单打开一个表单

I can get the new added forms to "see" each other as a class and make a button to open one form from the other form

我可以得到"旧的"现有表格"看"彼此作为一个类，并创建一个按钮，从另一个表单打开一个表单。

I can get the "old" existing forms to "see" each other as a class and make a button to open one form from the other form.

问题是新表单不会从旧表单和副表单中作为可选类出现反之亦然（所有形式都在相同的解决方案中。）..我缺少什么？

The issue is that the new forms are not coming up as a selectable class from the old forms and vice versa (all forms are in same solution.).. what am I missing?

谢谢

推荐答案

您可能错过了命名空间。如果旧表单位于一个名称空间中而新表单位于不同名称空间中，那么如果要从另一个名称空间中调用一个名称，则需要编写完整名称空间（如MyNamespace.Form3），或者添加一个语句"using $ b $" b MyNamespace"在调用表单的开头。

You are probably missing the namespace. If the old forms are in one namespace and the new ones in a different namespace, then if you want to call one from the other you need to write the full namespace such as MyNamespace.Form3, or add a statement "using MyNamespace" at the beginning of the calling form.
