Michel,
I can't find any reference to a maximum string length (like I think there was/is in VFP). I ran the following code and it worked:

System.String myString = "";
for (int i = 0; i< 100000;i++)
{
	myString = myString + " ";
}

That beeing said I would reccomend using the StringBuilder for most string operations (especially the operation I did in the above example <s>)
