c# - Convert a Collection of Strings into Collection of GUID

Question

I am reading a collection of strings (of GUID format) from excel and want to store them in database as collection of GUIDs. I am just wondering is there any clean way to convert List<string> to List<Guid> using Linq. I am not interested in looping through.

Answer 1

Either LINQ:

List<Guid> guids = guidStrings.Select(Guid.Parse).ToList();

or List.ConvertAll which is a little bit more efficient because it knows the size:

List<Guid> guids = guidStrings.ConvertAll(Guid.Parse);
