我上课并保存了所有内容
为了在新类中重用它，我添加了它(debug/BankLib.exe)以引用并使用它的命名空间....
但是它有找不到命名空间的错误!!!!!!

but it has error that can not find the namespace!!!!!!
"

Error   1   The type or namespace name 'BankLib' could not be found (are you missing a using directive or an assembly reference?)   D:\Users\Roham\AppData\Local\Temporary Projects\WindowsFormsApplication1\Form1.cs   10  7   WindowsFormsApplication1

我该怎么办?

what do i do with this error?

推荐答案

我不确定我是否正确理解了您的问题.我假设以下内容:

1.您有一个在控制台应用程序项目中使用过的类.
2.现在，您想在另一个项目(Windows窗体项目)中重用该类，并为此添加了对控制台应用程序项目的引用.
3.您遇到了上面提到的错误.

如果假设正确，则需要将Class放入Class库项目中，确保它已生成，然后在Windows Forms项目中添加对该类库的引用(您不能添加对控制台项目的引用并使用一个类来自那个项目).

另外，您需要在尝试使用该类的地方导入该类的名称空间.

I am not sure whether I understood your question properly. I am assuming the following:

1. You have a class that you''ve used in a Console application project.
2. You now want to reuse the class in another project (A windows forms project) and for that you added a reference to the Console application project.
3. You are getting the above error you mentioned.

If the assumptions are correct, you need to put the Class in a Class library project, make sure it builds and then add a reference to that class library in your windows forms project (You cannot add a reference to a console project and use a class from that project).

Also, you need to import namespace of that class where you are trying to use that class.

您的问题不清楚.

我的理解是，您编写了一个包含函数和变量的类(* .cs或* .vb)，并且希望在另一个项目中使用它们.

如果是这样，请在Visual Studio IDE中打开您的新项目，然后执行以下操作，
项目->添加现有项目.然后浏览类文件并将其添加到您的项目中.

问候，

Hi,

Your question is not clear.

My understanding is that, you have written a class (*.cs or *.vb) with function and variables and you want to use them in another project.

If so, open your new project in Visual studio IDE and do the following,
Project -> Add Existing Item. and then browse the class file and add it in your project.

Regards,
Suresh

要重用类，必须将类构建为dll.为此，创建一个类库，构建它并在另一个类中引用dll.使用引荐来源网址类的名称空间.创建该类的对象，并且在引用程序类中具有访问说明符public的所有方法将在当前类中可用.

For reusing a class you have to build the class to a dll. For that create a class library ,build it and refer the dll in another class. Use the namesapce of the referrer class. Create a object of the class and all the methods with access specifier public in referrer class will be available in current class.
