See more:

SqlConnection constr= new SqlConnection(@"Data Source=.\SQLEXPRESS; 
                         Integrated Security=True ; Database=abc");
  
string conn = constr.ToString();
              
return conn;

Simpy do

constr.ConnectionString.Tostring()

It's just waste of time to assigning and then fetching back.

Instead do the following.

String cs = //Yours connection string

SqlConnection Con = new SqlConnection(cs);

That will be preferable I think.

The SqlConnection object is not needed to be converted to string. I guess, the phrase "Connection String" confused you to try to convert it to string. You don't need to do that.

Once you obtain the SqlConnection object and open the connection, you can execute commands using the SqlConnection object.

C#

public string Connect()
    {
        return System.Configuration.ConfigurationManager.AppSettings["conn"];
    }

What do you want to achieve after converting constr to string. But if you still want then, you can write your own extension method or override the ToString method that will do the things that you require.
