not allowing to update value for a specific index

Question

I'm having problem in assigning a value to the specific index in the string after checking on the same index: Here below is my code:

"bits" is a string and "dirtybit" is an integer.

if (bits.ElementAt(dirtybit).Equals('1'))
      bits[dirtybit] = '0'; //shows red underlined error

Error:

Property or Indexer String.this[int] cannot be assigned to -- is only read

Why can I not access the same index (value)?
Is there any workaround?

You can use unsafe code and pointers. But i dont think you really need this. Other way You can use char array and convert it to string when its needed. — M.kazem Akhgary, Nov 22 '15 at 21:09

Strings are immutable in C#. You can not change them after you have created them.

You can use StringBuilder to create a new string.

From MSDN:

Strings are immutable--the contents of a string object cannot be changed after the object is created, although the syntax makes it appear as if you can do this.
