问题描述

当您需要将流重置为开始时(例如 MemoryStream)是使用的最佳实践

When you need to reset a stream to beginning (e.g. MemoryStream) is it best practice to use

stream.Seek(0, SeekOrigin.Begin);

或

stream.Position = 0;

我已经看到两者都运行良好，但想知道一个是否比另一个更正确?

I've seen both work fine, but wondered if one was more correct than the other?

推荐答案

设置绝对位置时使用Position，设置相对位置时使用Seek.两者都是为方便起见而提供的，因此您可以选择适合您代码风格和可读性的一种.访问 Position 要求流是可查找的，以便它们可以安全地互换.

Use Position when setting an absolute position and Seek when setting a relative position. Both are provided for convenience so you can choose one that fits the style and readability of your code. Accessing Position requires the stream be seekable so they're safely interchangeable.
