[英]Adding existing project in c#
I have add the existing project in my new project, but when I try to use the existing library, I see the following error:我已经在我的新项目中添加了现有项目,但是当我尝试使用现有库时,我看到以下错误:
the type or namespace name 'com' could not be found (are you missing a using directive or an assembly reference?)
找不到类型或命名空间名称“com”(您是否缺少 using 指令或程序集引用?)
What would cause this?什么会导致这个?
you must add in your main project reference to other project您必须在主项目中添加对其他项目的引用
(project's property -> add reference -> projects -> select your second project ) (项目的属性 -> 添加参考 -> 项目 -> select 您的第二个项目)
or you must add或者你必须添加
using com;
If you have already added the reference to the project then try adding a using
for the added class in the.cs file where you want to use it:如果您已经添加了对项目的引用,请尝试在要使用它的 .cs 文件中为添加的 class 添加
using
:
using com;
Right click the name of the project you want to add the library to > Select Add Reference , in the dialog box, > select Projects.右键单击要将库添加到的项目名称 > Select Add Reference ,在对话框中 > select Projects。 > Select and ADD the library.
> Select 并添加库。
Reference the library in the 'using' section of any class you wish to access the library.在您希望访问该库的任何 class 的“使用”部分中引用该库。
using System;
using <nameofproject>
