This article mainly explains "how to convert sequences or collections by LINQ". Interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn "how to convert sequences or collections by LINQ".

A conversion sequence or collection.

We cannot convert sequences from T type to U type in C # or VB, even if T inherits from U class. Therefore, even converting List to List is difficult to achieve. For an explanation of why, see Bick Byer's post. But if you want to convert IEnumerable to IEnumerable, there is a simple and effective LINQ solution:

IEnumerable strEnumerable =... ; IEnumerable objEnumerable = strEnumerable.Cast ()

If we need to convert List to List, we also provide a LINQ solution, but it copies the list:

List strList =... ; List objList = new List (strList.Cast ())

Chris Cavanagh suggests another solution:

Var objList = strList.Cast (). ToList (); at this point, I believe you have a deeper understanding of "how LINQ converts sequences or collections", so you might as well do it in practice.
