Temporary, non SQL, free table 1

[florindaniel]

Hello,

I need some sort of simple, non SQL based tables to be used temporary in a C# App.
I just need to create them (with 3 or 4 fields), populate them from a text file, have some statistics
based on some index field and then discard them.
Is there such a mechanism ?

Thank you,
Daniel

If the text file will always have the same structure, you could design a DataSet that will hold the data. Then you would read the file, split the data and add it to the DataSet.

Another way to do this would be to create a class that has all of the fields from the data. You would read the data into an object of that class. If there is more than one row, you would add each object to a List of objects of that class and then continue your processing.

I have used both of the methods on various projects.

Thank you, Dell

I'll go with DataSet.

Does it have Seek / Locate mechanism?

Thank you,

Yes, it does. If you pre-define a DataTable in your DataSet, you can indicate which fields are keys and VS will automatically create "Find" methods for those keys. If you don't want to do that, you can use the Select() method of a DataTable to find data based on a selection formula. The code for this will look something like this:

groups = dsAuditInfo.reportSecTable.Select(string.Format("reportID = {0}",myReportID));
