Oh come on. If the length of the string is returned an int, don't you think it would be the maximum size of a 32-bit int?

2147483647 bytes

I hope he is not going to allocate that big of string...

The Length property restricts the size to 2147483647 characters. .NET strings are stored as Unicode (UTF-16), so the maximum size is about 4 GB.
Of course, there may be other restrictions in the .NET runtime that prevent objects from being more than 2 GB (I think even the 64-bit .NET runtime has this restriction), so the actual limit may be a lot lower than that.
In my experience, anything larger than 200M characters and you're very likely to run into OutOfMemoryExceptions.

4 GB would be the maximum size of a string variable.
Until now, a few people found it lot less than that. So I have to try myself character by character to determine the exact size.

What on earth would possess someone to ask this, instead of writing code to find out ?

How big is your hard drive?
How big is your RAM?
How big is your imagination?

Reason for my vote of 1
Yes it does: see JSOP's reply re the Length property. In practice you will hit other problems such as memory issues before loading up a string that long. Roughly the max string could be 2 gig, but the real issue is getting enough memory from the heap as an allocation, which would limit one to half that size.
