Question

I am trying to use the function found here:
DataTable to List<object>

  public static IList<T> ConvertTo<T>(DataTable table)
        {
            if (table == null)
                return null;

            List<DataRow> rows = new List<DataRow>();

            foreach (DataRow row in table.Rows)
                rows.Add(row);

            return ConvertTo<T>(rows);
        }

the return statement is giving me an exception stating:

The best overloaded method match for 'Utilities.Utility.ConvertTo<T>(System.Data.DataTable)' has some invalid arguments

Can someone help me fix this error??

Don’t do it that way use Marc’s amazing function ( https://stackoverflow.com/a/545429/215752 ) I mean really… that is exactly what you want.. right?

You need another function

public static IList<T> ConvertTo<T>(IList<DataRow> rows)
    {
        IList<T> list = null;

        if (rows != null)
        {
            list = new List<T>();

            foreach (DataRow row in rows)
            {
                T item = CreateItem<T>(row);
                list.Add(item);
            }
        }

        return list;
    }

The question you link had a link in it. I’d suggest looking there for more info:

There you will find all the code, which I expect will compile. I won’t vouch for the reliability or reasonably of using it however.
