Creating an object with dynamic properties in C#

I'm using linq to load a csv file, but because the csv may have any number of columns, the object that it returns will need dynamic properties, and I can't figure out how to do that.

var data = from row in csvData
       let col = row.Split(',')
       select new
              {
                  Field1 = data[0],
                  Field2 = data[1],
                  Field3 = data[2] // etc, etc
              };

If possible, I'd like to name the properties by the name given in the csv file, rather than field1, field2, etc.

Thanks!

You could just do is simply using arrays or even a Dictionary but if you want to do something cool with Dynamic check out Clay

What would you do with this afterwards? If you know the names elsewhere and you're using .NET 4, you could use ExpandoObject - populate it by using it as a dictionary, and then access the property names using dynamic typing later. But if it's all dynamic (i.e. you don't know anything statically anywhere), why don't you just use Dictionary<string, string>?
