Performance analysis for String and StringBuilder

Sometimes small-small changes in our code really makes a huge difference to a performance. There are many tips and tricks available and among those, one I am going to discuss over here. I'll be talking about  String vs StringBuilder. One needs to be very careful while playing with strings because memory wise there is a huge impact of strings. I  know, there are lots and lots of articles available on net on String and StringBuilder, but still I am going to show this, using some statistics. Here I am taking Fx 4.0 C# console application with different static methods to showcase my analysis.  Basically what I am doing here is, I am having a String variable named  outputString  and just looping that for 1000 times and concating the string to variable outputString.  Please note, concatenation is done using + symbol. So, what happens internally is, whenever concatenation is done using + symbol, every time, new String object is created. So, as with my snippet. Here I am  lo
