How to query a Datatable using LINQ and add values to a List?

Question

Sample Class:

public class ProductData
{
    private Guid ProductID { get; set; }
    private string ProductDescription { get; set; }

    public ProductData(Guid pID, string pDescription)
    {
        this.ProductID = pID;
        this.ProductDescription = pDescription;
    }
}

Create a list of ProductData:

    private static List<ProductData> GetProductDataList()
    {
        // code to populate DataSet ds here

        DataTable dtReport = ds.Tables[0];
        List<AssetData> lstProductData = new List<ProductData>();
        int index = 1;
        foreach (DataRow row in dtReport.Rows)
        {
            lstProductData.Add(new ProductData(new Guid(row["ProductID"].ToString()), row["Product"].ToString()));
            index++;
        }

        return lstProductData.ToList();
    }

Code works perfectly fine and as expected. But, I think the foreach loop can be avoided using LINQ. I try to utilize LINQ as much as possible for various reasons (cleaner looking code is one of the reason - correct me if I am wrong).

Is there any way I can achieve the same thing as above using LINQ and with minimum code.

This can be done using Select and ToList:

var lstProductData = dtReport.Rows.Cast<DataRow>()
    .Select(row => new ProductData(new Guid(row["ProductID"].ToString())
        , row["Product"].ToString()))
    .ToList();
