I want to know about the string value in the c# in detail that actually what it is?

String in C# is a class and hence all the variables would be reference type. As it is a class you would be having many methods which u can use on the string objects such as length, search, copy and compare, Also we would have the constructor and destructor functionality provided with it also we have garbage collector in C# hence memory allocated to the strings would be taken care off.
