字符串对象之间的区别 [英] difference between String objects

问题描述

有什么区别

what is the difference between

String s = "xyz";

和

and

String s = new String("xyz");

推荐答案

第二条语句不会编译.没有将字符串作为参数的String 构造函数(. http://msdn.microsoft.com/en-us/library/system.string.string.aspx [

The second statement won''t compile. There is no String constructor that takes a string as an argument (.http://msdn.microsoft.com/en-us/library/system.string.string.aspx[^]).

String代表System.String，它是.NET Framework类型. string是System.String的C#语言的别名.它们都被编译为IL(中间语言)中的System.String，因此没有区别.选择您喜欢的东西并使用它.如果您使用C#编写代码，则我更喜欢字符串，因为它是C#类型的别名，并且为C#程序员所熟知.

String stands for System.String and it is a .NET Framework type. string is an alias in the C# language for System.String. Both of them are compiled to System.String in IL (Intermediate Language), so there is no difference. Choose what you like and use that. If you code in C#, I''d prefer string as it''s a C# type alias and well-known by C# programmers
