推荐答案

一个区别是第二个甚至没有编译，因为字符串没有没有参数的构造函数.

如果可以的话，我想明显的区别是，第一个将创建一个字符串，内容将为"prakash"，第二个将导致一个空字符串...

One difference is that the second on doesn''t even compile since string doesn''t have a constructor without parameters.

If it would work then I guess the obvious difference is that the first one will create a string and the contents will be "prakash" and the second one would result to an empty string...

没有真正的区别，只是构造器版本不会编译(不存在不带参数的字符串构造器).

当您输入

There is no real difference, except that the constructor version will not compile (there is not string constructor which takes no parameters).

When you type

string s = "prakash";

在C#中，编译器将其解释为隐式

in C#, the compiler interprets it as an implicit

string s = new string(new char[] {'p', 'r', 'a', 'k', 'a', 's', 'h'});
