将字符串集合转换为GUID集合 [英] Convert a Collection of Strings into Collection of GUID

问题描述

我正在从 excel 中读取一个字符串(GUID格式)集合，并希望将它们作为 GUID集合存储在数据库中.我只是想知道是否有任何干净的方法可以使用 Linq 将 List< string> 转换为 List< Guid> .我对循环不感兴趣.

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.

推荐答案

任一LINQ:

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

或 List.ConvertAll ，效率更高，因为它知道大小:

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

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