Linq2Sql没有显示在C＃类中

Question

I have a Asp.NET C# Project where i have created a Linq2SQL Model.

In a file i have to use it and somewhy its not showing up in intelicense form visual studio.

when i try to use InformitoDatabaseDataContext db = new InformitoDatabaseDataContext(); it doesnt recognize InformitoDatabaseDataContext.

The name of the .dbml file is InformitoDatabase.dbml

Solution Explorer

Image of Project (Update)

What can i do to "connect" the dbml file to my class?

Answer 1

I suspect the problem is that you're using ...DataContent when normally it would be ...DataContext , with an x instead of an n .

(Your screenshot shows the failure - with a different name from the one in the question - but not where the context itself is declared, which leaves us guessing somewhat... but as UserChosenPrefixDataContext is the default, it's highly likely that's what's wrong.)

EDIT: You've now changed your post to talk about SchoolDatabaseDataContext , but in the screenshot highlighting the failure, you're referring to InformitoDatabaseDataContent .

Answer 2

我很确定默认值为DataContext，而不是DataContent。

Answer 3

I find the solution, the problem is that you are missing InformitoDatabaseDataContext.designer.cs class Check you are missing it or not.

I just add a dbml file to aap code folder, it consist of three files,

1. informitodatabase.dbml
2. informitodatabase.dbml.layout
3. informitodatabase.designer.cs

when I add a new file in the root directoy it misses the designer file When I created the object of both the files, the file which is present in App_Code folder is accessible while other one is not accessible.

See the below image file, I added two files in App_Code folder and two in the Root Directory.
