ASP.NET connection String Error help needed

Question

I am new to asp.net. Here is my issue. Please help.

I am trying to connect to my database which is also on the local machine as my asp.net project. I am using the following connection string

SqlConnection con = new SqlConnection("Data Source= NGEST1AND2\SQLEXPRESS;Integrated Security=True;Connect Timeout=15;Encrypt=False;TrustServerCertificate=False");

I get an error under SQLEXPRESS (Unrecognised escape sequence) . I tried to rectify this error with a \\\\ and then the error goes away but I get another error saying unable to connect to database.

Ay help will be greatly appreciated.

Thanks Gerard

Answer 1

SqlConnection con = new SqlConnection(@"Data Source= NGEST1AND2\SQLEXPRESS;Integrated Security=True;Connect Timeout=15;Encrypt=False;TrustServerCertificate=False");

放在@开头

Answer 2

try this

SqlConnection con = new SqlConnection(@"Data Source= NGEST1AND2\SQLEXPRESS;Integrated Security=True;Connect Timeout=15;Encrypt=False;TrustServerCertificate=False");

Put @ before your connection string.
