如何使用受信任的连接正确访问我的SQL Server数据库？

Question

Dim connString As String = "Server=(LocalDB)\MSSQLLocalDB;Database=Database1.mdf;Trusted_Connection=True"

Dim cnn As New SqlConnection(connString)

cnn.Open()

I am using the above code in my program and the connection seems to work but for some reason it says

Cannot open database "Database1.mdf" requested by the login. The login failed. Login failed for user 'Alex\\John'.

I have no clue why it won't let me log in since i set it as trusted. Is there something behind the scenes that I am missing?

Answer 1

You are connecting to a mdf . That is the database file, you need to connect to a server

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

Sql Connection Strings

Answer 2

connectionString="Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=Database1.mdf;Data Source=Alex-PC;"

connectionString="Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=Database;Data Source=Alex-PC
