function's parameters

agree that objects will be passed as reference automatically since in java is also a same case ... but String is also the same case then why function can't modify the original string...

System.Text.StringBuilder is a string class which you can modify without creating new one

yes, actually... good point here
;)

No...

if you read the documentation you will get the information that:
"This class represents a string-like object whose value is a mutable sequence of characters." :)

It is really not a string. Internally it doesn't use string to hold content of the StringBuilder class. And you have to convert that class into the string using ToString() member...

So you cannot modify string content using that class.

There is really no way to modify existing instance of the string class... Maybe weird, but it is true!

Didn't meant to say that its exactly like string.

Yes... OK...

However you cannot modify string's value using it... :D You can just create new instance of string... :D :D :D

Yeah guys... I made one mistake...

StringBuilder uses internally string. I am looking into its sources now... :)

However after every operation with StringBuidler it calls function ReplaceString. This is its body:

Code:

---

private void ReplaceString(int tid, String value) {
            BCLDebug.Assert(value!=null, "[StringBuilder.ReplaceString]value!=null");
           
            m_currentThread = tid; // new owner
            m_StringValue = value;
        }

---

So it creates new instance of string class everytime you make some changes in content of StringBuidler... :D :D :D

lol. sounds like something that m$ wrote :)

so in the assence stringbuilder takes more memory...
Paresh

although string class is reference type, it use like a value type..

hehe...
