ToString的约定(Conventions for ToString)

 t = t.Escape(); 是.NET中用于更改字符串的常用习惯用法。 例如t = t.Replace("a", "b"); 我建议你用这个。 这是必要的，因为字符串是不可变的 。 
 
 有很多方法，但它们是IMO的丑陋。 例如，您可以使用ref参数（但不能使用扩展方法）： 
 
public static string Escape (ref string string_2) { ... }
Util.Escape(ref t);
 
 或者你可以创建自己的类似String的类是可变的： 
 
public class MutableString { /** include implicit conversions to/from string */ }
public static string Escape (this MutableString string_2) { ... }

MutableString t = "'";
t.Escape();
 
 我要提醒你，如果你使用t = t.Escape();之外的任何东西t = t.Escape(); ，因此偏离正常使用，您可能会混淆将来读取代码的任何人。 

t = t.Escape(); is the usual idiom in .NET for changing a string. E.g. t = t.Replace("a", "b"); I'd recommend you use this. This is necessary because strings are immutable.
 
There are ways around it, but they are uglier IMO. For example, you could use a ref parameter (but not on an extension method):
 
public static string Escape (ref string string_2) { ... }
Util.Escape(ref t);
 
Or you could make your own String-like class that's mutable:
 
public class MutableString { /** include implicit conversions to/from string */ }
public static string Escape (this MutableString string_2) { ... }

MutableString t = "'";
t.Escape();
 
I'd caution you that if you use anything besides t = t.Escape();, and thus deviate from normal usage, you are likely to confuse anyone that reads the code in the future.
