CSV to object model mapping

Question

I have a CSV file that I want to read into a List. Here\'s an example file:

Plant,Material,\"Density, Lb/ft3\",Storage Location
FRED,10000477,64.3008,3300
F         


        

Answer 1

I wrote a simple library to allow developers to use LINQ on CSV files. Here is my blog post about it: http://procbits.com/2010/10/11/using-linq-with-csv-files/

In your case, you would have to change your header string to look like this:

Plant,Material,DensityLbft3,StorageLocation

And then you could parse the file like this:

var linqCSV = new CsvToXml("csvfile", true);
linqCsv.TextQualifier = null;

linqCsv.ColumnTypes.Add("Plant", typeof(string));
linqCsv.ColumnTypes.Add("Material", typeof(int));
linqCsv.ColumnTypes.Add("DensityLbft3", typeof(double));
linqCsv.ColumnTypes.Add("StorageLocation", typeof(int));

linqCsv.Convert();

You could then use LINQ like this:

var items = from item in linqCsv.DynamicRecords
            where item.Plant == "Fred" && item.DensityLbft3 >= 62.6
            orderby item.StorageLocation
            select item;

Hope that helps or works for you.
