  Hello,

  if the concatenations are more than 5, use StringBuilder.... this is the example rule of boban...The same way you can define your own rule and see what is best for you. If there are more number of modifications on the string, it is better to use StringBuilder.

  There is no defined rule when to use string concatenation versus StringBuilder. Working with StringBuilder not always give's you performance. My rule is when i have loop in which i concatenate or modify strings then i use StringBuilder, but when i know that number of loops will be higher than 5 for example. Also i try always to specify Capacity of StringBuilder when possible.

  Yes, you are right. One should use StringBuilder if there is number of concatenations. This will give you better performance compare to using "+" with string type.

  Following explains about StringBuilder

  Hope this helps you!!!!
