Unable to connect to SQL Server database using C#


I'm currently working on a wpf application where I tried to create a database. I used data sources > add new datasource > dataset and copied the query string for its properties, but it is giving me the following exception:

What might be the problem? This is a local database... and when I click on the test connection button it writes "test connection succeeded"

Thanks


Solution

  • You are using a SqlConnection rather than the SqlCeConnection that you require. SqlConnection is for connecting directly to a "real" sql server.

    Take a look at the MSDN for more information.
