所以这实际上是我在c＃中的一个字符串，我想用table替换tbody ，所以我试着这样做：

 _viewPath.Replace("tbody", "table"); 

但它没有用。 为什么？

Answer 1

你应该做：

 _viewPath = _viewPath.Replace("tbody", "table"); 

Answer 2

因为string.Replace不修改字符串，所以它返回一个新字符串

 _viewPath = _viewPath.Replace("tbody", "table"); 

会做的伎俩。

Answer 3

字符串是不可变的。 这意味着你不要修改它们 – .Replace返回一个新字符串。 试试这个：

 _viewPath = _viewpath.Replace("tbody", "table"); 

Answer 4

你应该保存Replace的结果： _viewPath = _viewPath.Replace("tbody", "table");

Answer 5

Replace实际上是一个函数 ，并返回结果。 你必须这样做：

 var Result = _viewPath.Replace("tbody", "table"); 

结果包含转换结果。
