The   symbol serves 2 purposes in C    Firstly  it allows you to use a reserved keyword as a variable like this   int  int   15    The second option lets you specify a string without having to escape any characters  For instance the     character is an escape character so typically you would need to do this   var myString    c   myfolder  myfile txt    alternatively you can do this   var myString     c  myFolder myfile txt

An important point that the other answers forgot  is that   keyword  is compiled into  keyword  in the CIL   So if you have a framework that was made in  say  F   which requires you to define a class with a property named  class   you can actually do it   It is not that useful in practice  but not having it would prevent C  from some forms of language interop   I usually see it used not for interop  but to avoid the keyword restrictions  usually on local variable names  where this is the only effect  ie   private void Foo       int  this   2      but I would strongly discourage that  Just find another name  even if the  best  name for the variable is one of the reserved names
