Solution 2

Because string type is immutable(You can't change the content of the object once it's been defined).

Ex.

string str = 'Hi';
str = str + ' all';

In second line, CLR create another object of string type, inspite of using existing string object.

It is confusing because string is a reference type that has (by the C# designers) been created to act in some cases as a value type.

So, for example, we can do string comparisons as s1 == s2 which actually compares the value of the strings, not the object references as it would with a 'true' reference object.

I believe they did it like that to be more intuitive - although IMHO it just leads to more confusion for beginners.
