Although not one of the choices in the original post, I think it's a good answer given that the OP is a load of, umm, excrement.

Then how its by value???
Once its passed, you wont get the original.......

For some reason, I sense you are asking a programming question. That is a big NO in this particular forum.

this looks like a programming question.
On top of this forum it's said in big bold red letters:
Do not post programming questions in this forum...
If it is a question, move it to the C# forum. Btw: objects (including strings) are passed by reference to my knowledge. You should be able to find this on msdn somewhere.

Nope. All parameters are passed by value. you should use the ref keyword to pass a parameter by reference. BTW: passing by value an object implies that called function can actually change object's internal state.

This is incorrect. Classes are passed by reference, Structs are passed by value.

This means nothing of the sort. Passing by value simply means that an object in a method is distinct from the original object and any changes made to that object are not reflected in the original.

You are wrong. Whenever you pass an object, a reference to the object's instance is passed by value.

This appears to be C# code. Classes are passed by reference by design.

I guess it gets passed by reference because it is C#. 
In C++ by value.

Value-type objects such as structs are created on the stack, while reference-type objects such as classes are created on the heap.
So it is actually a PASS - BY - REFERENCE
Both types of objects are destroyed automatically, but objects based on value types are destroyed when they go out of scope, whereas objects based on reference types are destroyed at an unspecified time after the last reference to them is removed.
Happy Coding!

The object is passed by value, but the what is actually passed since it is a reference object is a pointer to the object. So, the "value" that is actually passed is the pointer not the object and therefore any changes made through the pointer change the original object. What you can't change is the pointer itself. That is the "value".

You are right Jon. I see your point.

I found this little gem in an app I worked on recently.
switch (strValue.GetLength())
{
case 1:
{
strValue = "00000" + strValue;
break;
}
case 2:
{
strValue = "0000" + strValue;
break;
}
case 3:
{
strValue = "000" + strValue;
break;
}
case 4:
{
strValue = "00" + strValue;
break;
}
case 5:
{
strValue = "0" + strValue;
break;
}
case 6:
{
break;
}
}
And yes, the code I replaced with comments is the same for all 6 cases.

Hey, those zeroes are valuable, you can't just go throwing them around willy-nilly!!
Sure, it could have been done with a single append then take the right 6 chars, but how many 0's would have been needlessly lost? Consigned to the bit-bucket of history, before their time... Show some mercy, man!!

Nice. Did you fire up the blame engine (source control) and find the culprit?

It does not work that well with outsource contractors! (I have seen similar code from those).

That was, in fact, my first reaction. I found the culprit, and he still works here.
