C＃Windows应用程序：使用Windows身份验证连接到远程SQL Server 2008的连接字符串

Question

I am developing a windows form application using c#. I want to connect to SQL Server 2008 which is in the server using windows authentication. Can anyone please provide me the connection string?

Note:

1. Domain is created in my server.
2. Remote access is enabled for the sql server
3. TCP/IP port is also enabled.

Please help me.I am struggling for this since 3 days.

Answer 1

Server=myServerAddress;Database=myDataBase;Trusted_Connection=True;

Answer 2

如果是本地的，你可以尝试一下。它将使用默认实例。我认为这会帮助你

Data Source=.;Initial Catalog=yourDBName;Integrated Security=True

Answer 3

I am not clear on the issue you are facing, are u running the Application on your domain cred, and you're able to access the DB? . What is your current DB connection string template? (3 days, seems like a long time for this issue, i must be missing something)

Answer 4

Follow the below steps in your visual studio,

1. Go To Tools menu and click on "Connect to Database".
2. If it is a first time a small window will open with below options
   • Microsoft Access Database File
   • Microsoft ODBC Data Source
   • Microsoft SQL Server
   • Microsoft SQL Server Comapct 3.5
   • Microsoft SQL Server Database File
   • Oracle Database
3. In your case, click on "Microsoft SQL Server" and click Continue.

4. Then a new window will prompt which takes input like -Server Name -choose your server name (First time it will take some time to load list of server name). You can get your server name by opeing SQL Server.

   • Log on to the server

   option 1 - Use Windows Authentication (As this is the first time you are using, I will suggest to use this option) option 2 - use SQL Server Authentication (If your choosing this, provide your SQL Server Username and password)

5. Connect to Database -Select or Enter the Database name (From the Dropdown select your database to which you want to connect)
6. After filling above details, Click on "Advanced" button and it will take you to another pop-up window
   • In that window, just above "Ok" button there will be a non-editable column with name DataSource. Simply copy the text under it. This is you Connection string.
