A:
Yes, they are identical. string is just the C# name for a System.String, which you can also use. See MSDN:
The string type represents a string of Unicode characters. string is an alias for System.String in the .NET Framework.
It's personal preference, but I always use string over String. I guess I like the blue color over the, uh, turquoise color offered by the default syntax highlighting.
You can see the other aliases under the C# value types on MSDN (e.g. int is really System.Int32 while long is really System.Int64).

A:
You get this question a lot because in java there is a difference between for example Integer and int (pointer allocation). In C# there is no difference between String and string, nor there is a difference between Int32 and int etc..

This is wrong, as has been discussed countless times already here on StackOverflow. `string` is an alias for `System.String`, i.e. it will *always* be the framework class. `String` follows the normal lookup rules, i.e. it will use *any* class named `String` which happens to be in scope.

euhm.. this isn't wrong ?? any good programmer would not create their own String class (and if they must they would name it MyString or something)..And I just pointed out that in JAVA there is a difference between a primitive (int) and an object (Integer).
