c# - 在 C# 中编辑字符串中的字符

Question

在 C# 中编辑字符串中的字符最简洁的方法是什么？

C++ 中的 C# 等价物是什么:

std::string myString = "boom";
myString[0] = "d";

Answer 1

使用 StringBuilder 代替。

string is immutable as described by MSDN :

Strings are immutable--the contents of a string object cannot be changed after the object is created, although the syntax makes it appear as if you can do this.

所以你想要这样的东西:

 StringBuilder sb = new StringBuilder("Bello World!");
 sb[0] = 'H';
 string str = sb.ToString();
