I suppose the USER-PC is the machine running the SQL server, but is the CompanyName the fixed instance name of the SQL server as you see it in the service manager, or is it a variable? In the second case you mean that the USER-PC machine is running several different instances of SQL server?

Solution 1

try this:
string sqlConn = "Data Source=USER-PC\\CompanyName;Initial Catalog=rack;User ID=trial;Password=trial112";

If it's local PC, use dot as :

"Data Source=.;Ini.....

If you are struggling with name try to ping User-PC\CompanyName...

The syntax of connection is:

Server\Instance, Port
Default port(SQL) - 1433

Verify you can connect.

When you initialize any string make sure that escape special charcters..
\ is a special charcater and you need to escape it as \\

Solution 2

string sqlConn = "Data Source=USER-PC\CompanyName;Initial Catalog=rack;User ID=trial;Password=trial112";

see data-source value it should be same as you find in login window while open your sql server
'server name' = xyz\SQLEXPRESS

connection string should like below
string sqlConn = "Data Source=xyz\SQLEXPRESS;Initial Catalog=rack;User ID=trial;Password=trial112";

Happy Coding!
