Converting Generic Lists to Strings using C#

Let's say I have two generic lists: one is a g-list of integers (List<int>) and the other is of a custom class (List<StoredProcedureInfo>).  First, I want to convert the list of integers to a comma-delimited string:

=================================
List<int> integerList = new List<int>();
integerList.Add(4);
integerList.Add(132);
integerList.Add(36);
// How do I retrieve the values in [integerList] as a comma-delimited string?
=================================


Let's say my custom class, StoredProcedureInfo, has four properties: ID (int), Name (string), Text (string), Checked (bool).  Is there an easy way to get all of the ID property values in List<StoredProcedureInfo> as a comma-delimited string?

That's what I'm looking for.  But there's no built-in method of a generic list that offers the same functionality, is there?

Hi, not that I'm aware of... the String.Join allows you to create a CSV string by specifying a delimiter and a string array whose values will be concatenated into one string (seperated by the delim you specify as the first param)... but there doesnt seem to be a prewritten method that you can use for this type of functionality with generic lists... let alone generic lists with a specific property of the underlying type (like your ID property).


Hope this helps!
