Solution 2

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[^]).

Do you perhaps mean that there is no string constructor that takes a string as a parameter?

Sergey Alexandrovich Kryukov 18-Sep-12 16:36pm

You are right, but I don't see a way to understand "There is not such a string constructor" in any other way. This phrase says the same.

No actually it does not. One way means that there is not a constructor for a string and the other means that there is no constructor that takes a string.

CodeHawkz 18-Sep-12 15:28pm

Indeed, it won't compile since the String class have not got a constructor with a string parameter. But there are other string constructors and is very useful in some cases :)

Sergey Alexandrovich Kryukov 18-Sep-12 16:35pm

Correct. The answer deserves my 5 anyway, but this comment is a useful clarification.

Solution 1

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

How is it related to the OP question?

[no name] 18-Sep-12 15:32pm

Not related at all. Almost smells of sock puppetry.

Sergey Alexandrovich Kryukov 18-Sep-12 16:33pm

Somewhat related. The information in this answer is correct, only OP did not ask about "string" vs. "String" but about not calling a constructor explicitly (first like).

[no name] 18-Sep-12 16:39pm

And therfore not at all related to the OPs actual question. Whether the information is correct or not is immaterial in that it does not in any way answer the OPs question.

Sergey Alexandrovich Kryukov 18-Sep-12 17:26pm

I agree, formally, but it can also give a hint for OP to do an extra effort and finally clear this doubt. The answer is not excellent, sure, but not too bad.
