Question

How can I add data into a SQL Server Express database?

I have written the following code

 SqlConnection conn = new SqlConnection();
 conn.ConnectionString = @"Data Source=.\SQLExpress;" 
    +"User Instance=true;" +  "Integrated Security=true;" 
    +  "AttachDbFilename=|DataDirectory|GCdatabase.mdf;";
 conn.Open();
 //...
 conn.Close();

Is this right?

If yes then how can I add data into table ?

There are several ways of doing that. One of them is using a SqlCommand object with an insert SQL statement:

SqlConnection conn = new SqlConnection();
conn.ConnectionString(/* your connection string goes here */);
conn.Open();
SqlCommand cmd = new SqlCommand("insert into table values (1, 2, 3)", conn);
cmd.ExecuteNonQuery();
conn.Close();
