问题描述

C＃：是什么占用更多的内存？一个字符串或字节？

C#: What takes up more memory? A string or bytes?

让我们说我有一条线，上面写着我的文本，以何种形式将这一行占用更多的内存，作为一个字节或一个字符串？

Let's say I have a line that reads "My Text", in which form would that line use up more memory, as a byte or a string?

推荐答案

字节数组。这将存储您的文本为ASCII（每个字符1字节）字符，而.NET字符串使用统一code这是更大的。但是请记住，.NET字符串可能更有用，并在大型应用程序的差别可能不会产生巨大的变化。

The byte array. This will store your text as ASCII (1 byte per character) characters, whereas a .NET string uses Unicode which are larger. However remember that .NET strings are probably more useful and in a large application the difference probably won't make a huge difference.

（请注意，如果你只是用ASCII字符在.NET字符串，然后字符将仍然只有1个字节）

(note also that if you just use ASCII characters in your .NET string then the characters will still only be 1 byte each)
