    The issue with your code is that you are missing a closing parenthesis in your SQL INSERT statement. The correct statement should be:

    SqlCommand insertcommand = new SqlCommand("INSERT INTO dbo.users(NAME, EMAIL, PASSWORD, COUNTRY) VALUES (@username , @useremail , @userpassword , @usercountry)");
    

    Notice the closing parenthesis at the end of the statement.
