如何将cs文件添加到现有C＃项目？

A while back I wrote a little program in Microsoft Visual C# 2008 Express Edition. In it included a file called "ProblemReport.cs" with it's own form and ProblemReport class.

不久前,我在Microsoft Visual C#2008 Express Edition中编写了一个小程序。其中包含一个名为“ProblemReport.cs”的文件,其中包含自己的表单和ProblemReport类。

I'm writing a new program and want to reuse this code. (still working in MS Vis C# 2008 express)

我正在编写一个新程序,并希望重用此代码。 (仍在MS Vis C#2008快递中工作)

In my new program, in the C# Solution Explorer, I right clicked on my project and chose "Add existing item..." I then added ProblemReport.cs, ProblemReport.designer.cs and ProblemReport.resx.

在我的新程序中,在C#Solution Explorer中,我右键单击了我的项目并选择了“Add existing item ...”然后我添加了ProblemReport.cs,ProblemReport.designer.cs和ProblemReport.resx。

What step(s) am I missing here? When I go back to the main form in my new program, and try to instantiate a new instance of "ProblemReport", I get the error message:

我在这里错过了哪些步骤?当我回到我的新程序中的主窗体,并尝试实例化“ProblemReport”的新实例时,我收到错误消息:

"The type of namespace name 'ProblemReport' could not be found (are you missing a using directive or an assembly reference?)"

“无法找到名称空间名称'ProblemReport'的类型(您是否缺少using指令或程序集引用?)”

Obviously - I'm supposed to do something else to get this to work... just not sure what it is!

显然 - 我应该做点别的事情才能让它发挥作用...只是不确定它是什么!

Ensure that all your CS files are within the same namespace. Sounds like the imported one(s) aren't living with your new project.

确保所有CS文件都在同一名称空间内。听起来像进口的人没有和你的新项目一起生活。

Ensure that:

namespace MyProgram //same as the rest of your project
{

    public class ProblemReport
    {
    }

}

meanwhile in your other .cs files....

同时在你的其他.cs文件....

namespace MyProgram 
{

     public class SomeClass
     {
           public void DoSomething()
           {
               ProblemReport. //you should get intellisense here.
           }
      }

}

#2

You might be better off extracting ProblemReport into it's own class library (separate dll) so you only have one copy of the code.

您可能最好将ProblemReport解压缩到它自己的类库(单独的dll)中,这样您只有一个代码副本。

Create a new class library project, copy ProblemReport.cs, ProblemReport.designer.cs and ProblemReport.resx into that and update the namespace as required. Build it and put the dll somewhere central. Then add a reference to this class library from your two programs.

创建一个新的类库项目,将ProblemReport.cs,ProblemReport.designer.cs和ProblemReport.resx复制到该项目中,并根据需要更新名称空间。构建它并将dll置于中心位置。然后从两个程序中添加对此类库的引用。

#3

You have to add a "using" directive to your new project -

您必须为新项目添加“使用”指令 -

using ProblemReport;

Then you should be able to access the ProblemReport class. Of course this depends on the name of namespace of the ProblemReport.cs file.

然后您应该能够访问ProblemReport类。当然,这取决于ProblemReport.cs文件的命名空间名称。

#4

When you created it it's likely it used a different namespace, as those are generated from the project name by default.

在创建它时,它可能使用了不同的命名空间,因为默认情况下它们是从项目名称生成的。

In the .CS file does the namespace match that of the rest of your project?

在.CS文件中,命名空间是否与项目的其余部分匹配?
