Why string shows the behavior of value type, but it is reference type in .net?

I am little confuse about string. I know it's reference type but when i tried, it shows the behavior of value type. I tried this:

String a = "abc";

String b = a;

b="xyz";

//When i print both a and b

a is abc
b is xyz

I was expecting both a and b print as xyz. Because they are reference type. After that, i made a function

public static void change(string a)
{
    a="hello";
}
//In main i did this.

String a="abc";

Change(a);

I thought a will print as "hello" because it is refrence type but it still shows abc. If it is refrence type then why it behave like valu type?

In your examples I don't see string behaves like value types, it exactly behaves like reference types. – Cheng Chen Mar 04 '16 at 06:04
In reference type, when you copy one type to another then change in one effect on another object – CodeLover Mar 04 '16 at 06:08
string is immutable..... – Viru Mar 04 '16 at 06:11
`Foo a = new Foo(); Foo b = a; b = new Foo();` my code is essentially the same as your example. `string` behaves exactly the same as my class `Foo`. – Cheng Chen Mar 04 '16 at 06:11
