While it does not answer the OP's question precisely, depending on what you're doing it might be a good solution. Below is going to solve my problem.

Let's say that you have to do a lot of individual manipulation of various characters in a string. Instead of using a string the whole time use a char[] array while you're doing the manipulation. Because you can do this:

 char[] array = "valta is the best place in the World".ToCharArray();

Then manipulate to your hearts content as much as you need...

 array[0] = "M";

Then convert it to a string once you're done and need to use it as a string:

string str = new string(array);
