推荐答案

将光标置于代码中的"Dboperation"一词上.你有一条小红线吗?如果是这样，请将鼠标悬停在其上方，然后打开将出现的下拉菜单.您将从VS获得一些可以修复它的选项.
如果没有，则找不到Dboperation-您可能输入的大写错误，可能需要找到DLL，或将适当的.cs文件移动到App_Code文件夹中.

Place the cursor over the word "Dboperation" in your code. Do you get a small red line? If so, hover the mouse over it, and open the dropdown that will appear. You will gets options from VS that will fix it.
If you don''t, then Dboperation can''t be found - you may have got the capitalization wrong, you may need to locate the DLL, or move the appropriate .cs file into the App_Code folder.

对代码中包含类DBoperation missing的名称空间的引用吗?
该类本身也可能会丢失，因此请确保两者都不存在.

Is the reference to namespace that contains class DBoperation missing in your code?
Also the class itself could be missing so make sure its none of the two.

我猜这个Dboperation类位于与Login不同的名称空间中.因此，将其写为:-

Namespace.Dboperation Db =新的Namespace.Dboperation();

并引用项目中Dboperation所在的dll.

I guess this Dboperation class lies within a different Namespace than Login. So, write it as :-

Namespace.Dboperation Db = new Namespace.Dboperation();

and reference the dll in which the Dboperation lies in within your Project.
