Question

I need to test a database connection from my wpf application, that is, a method like:

bool TestCon(string dbserver, string user, string password, string dbname)
{
    bool success;
    // code
    return success;
}

I have seen I can use sqlcmd -S dbserver -U user -P password -d dbname, but it’s not clear how can I read an answer from sqlcmd so my program can say: connection successful!! or bad login!! or bad server!! Thanks.

Do you have to use sqlcmd? If not, you would be much better off to use ADO.NET…

bool TestCon(...)
{
  try
  {
    using(var connection = new SqlConnection("your connection string"))
    {
      connection.Open();
      connection.Close();
      return true;
    }
  }
  catch
  {
    return false;
  }
}
