Converting Generic Lists to Strings using C#

Hi, you can use the following method, it accepts a generic List and a string indicating the property to get the underlying data for CSVformat (see example below):

        private string GetCSVStringFromList<T>(List<T> list, string property)
        {
            string csv = string.Empty;

            if (property == null || property == string.Empty)
            {
                foreach (T item in list)
                    csv += item + ",";
            }
            else
            {
                try
                {
                    foreach (T item in list)
                        csv += item.GetType().GetProperty(property).GetValue(item, null) + ",";
                }
                catch
                {
                    return null;
                }
            }
           
            return (csv == string.Empty) ? null : csv.TrimEnd(',');
        }

To get a CSV formatted string of your integer list using above method:

      string integerListCSV = GetCSVStringFromList(integerList, null);

To get a CSV formatted string of your ID properties in a List<StoredProcedureInfo>:

      string idListCSV = GetCSVStringFromList(myStoredProcedureList, "ID");

      if (idListCSV != null)
      {
               //csv string was constructed ok...
      }

The method returns null if an error occurrs when using reflection to get the property values and also when the input list is empty.
