I am still trying to learn C#, much less how to handle data. Still, data handling, in my opinion, is a much more complex matter in .NET. Why does it have to be this way? It seems that there is a multitude of ways to handle data, using LINQ, ADO.NET, and so on. I just don't know where to begin. I just ordered Murach's ADO.NET 3.5 with C# book to see if this might help me a bit.

I don't think it is this way entirely with .NET data handling. There seem to be many more steps to handling data, unlike VFP and other xBased languages.

Yes, I got some frustration at first when starting to learn it. But, this is the same pattern for everything new. But, as is the case for everything I do, I always built classes to handle that. So, since a few years, for all applications I have done, it comes down to be as simple as this:
        Dim loDataProvider As Framework.Framework.Data = New Framework.Framework.Data(oProcess)
        Dim loRow As DataRow

        ' Do a SQL exec to retrieve one record
        loDataProvider.ParameterAdd("Numero", lnPrimaryKey)
        If Not loDataProvider.SQLExec("SELECT List.SomeField FROM List " + _
         "WHERE List.Numero=" + loDataProvider.ParameterAddSQL("Numero")) Then
            Return False
        End If

        ' Get it into a row
        loRow = loDataProvider.oDataView(0).Row

        ' Get the value
        lcValue = loRow("SomeField")
So, basically, you would only have to do it once, by building your own class for data handling such as the data provider class I have built. Or, you can go with commercial frameworks available which also uses the same approach.
