string is a reference type ..is it reference type?

Question

0.00/5 (No votes)

See more:

if i am passing a string to a function as parameter then it is passing as reference..Because it is reference type.

But if i am changing the value of the string in the function then it is not getting changed, because it is immutable(i got the answer like this)...

so normally when we want to pass a string as param, we never want to pass as reference..because it is already a reference...

but if i am trying to send the string as 'ref' then the value is getting changed...

How it is working.. because string is already a reference ??

C# has out (or ref, depending on your needs) keyword for that, see: "out parameter modifier (C# Reference)"[^].
