string or String?

[Bogdan]

As a mainly C/C++ and Java developer I was quite surprised when I realized
that C# compiler takes both "string" and "String" types. C# is case
sensitive so I'm a bit puzzled by that. Could someone please explain that
or point me to on-line docs?

thx

Re: string or String?

The string type represents a sequence of zero or more Unicode characters.
string is an alias for String in the .NET Framework.

Actually C# doesn't understand a String type. It does understand a
System.String type, and you can refer to that as just String, if you
happen to have a
using System;
statement at the top of your file (and it is some time since I saw a
C# file that /didn't/ have such a statement).

C# does understand the 'string' type, which it internally converts to
System.String32 (much as it converts 'short' to System.Int16).

My personal preference is to always use the C# names, unless I want to
emphasize the exact length of an integer (in which case, I'll use
System.Int64 or whatever).

I think most C# programmers will expect it to be there.

Me too.

But I suspect that it is because I also code in C/C++/Java.

D'oh! :-)

Perhaps, but I think I would recommend it as a good convention even
for a pure C# development.

This is also good practice if you are exposing the name as part of a method
(or other API etc), since the caller could be any language. Examples:
IDataReader.Get Int32(), Convert.ToInt64 ()
