c# - 如何将字符串的值设置为空

Question

我知道我可以像这样设置 null

string val = null;

但我想知道我可以将其设置为 null 的其他方法。是否有像 String.null 这样的函数我可以使用。

Answer 1

我觉得你看得很远 String.Empty

string val = String.Empty;

更新: TheFuzzyGiggler评论值得一提:

It's much better to set a string to empty rather than null. To avoid exceptions later. If you have to read and write a lot of strings you'll have null value exceptions all over the place. Or you'll have a ton of if(!string.isNullorEmpty(string)) which get annoying
