1. String is reference type. 2. Internally it uses Array to save value. 3. Array have fixed size. 4. If we are going to store dynamic value in string every time, that array will not store the same because of size. 5. So every time fresh objects are created. 6. Thats why string are immutable.

[@Girishur]

Dear sir thank you for efforts. String are immutable because strings are reference type and 1.multiple string variables with the same value then it will avoid allocating memory for the same string value multiple times. 2. immutable strings eliminate race conditions in multi-threaded applications

[@jayjeckel]

Strings are immutable and strings are reference type. They aren't immutable because they are reference type. A reference type can be mutable, for example List is a reference type and is mutable.

[@pratikgirme775]

Dear Sir, Thank you so much for giving such a clear understanding of this concept. I was aware of string is immutable, but how to prove it, I got this from this video.

[@jayjeckel]

Nice video. I especially like how you used the diagnostic window to show all the string objects being garbage collected.

[@_Ten_]

Great video.

[@maheshpatkar886]

The reason for string being immutable object is that in case of assignment of one string variable to another string , any change in the previous string would lead to unwanted changes in the copied string just like other reference types

[@Abdullah_khan333]

well explained

[@miscVideo007]

Why this behavior of string are there , i mean immutable ?

[@omkargorde7062]

What is the best way to avoid immutable functionality of string?

[@jayjeckel]

You can't. Strings are immutable and that can't be avoided using strings. If you need a string-like object that is mutable, then you should use the StringBuilder class.

[@ParidhiStyle]

Use string builder

[@ParidhiStyle]

Everyone it create new object. Because it is reference type.

[@atulparashar4846]

Because string is thread safe in c#
