Better way to sort array in descending order

Question

I have a array of int  which I have to sort by descending   Since I did not find any method to sort the array in descending order Currently I am sorting the array in descending order as below  int   array   new int     3  1  4  5  2    Array Sort lt int gt   array    Array Reverse  array      Now the question is that Is there any better way to do the same in c

Yes  you can pass predicate to sort  That would be your reverse implementation

Sure  You can customize the sort     You need to give the Sort   a delegate to a comparison method which it will use to sort   Using an anonymous method   Array Sort lt int gt   array  delegate int a  int b          return b - a    Normal compare is a-b          Read more about it   Sorting arrays MSDN - Array Sort Method  T    Comparison

Depending on the sort order  you can do this        int   array   new int     3  1  4  5  2        Array Sort lt int gt  array                      new Comparison lt int gt                                i1  i2    gt  i2 CompareTo i1                                or this        int   array   new int     3  1  4  5  2        Array Sort lt int gt  array                      new Comparison lt int gt                                i1  i2    gt  i1 CompareTo i2                            i1 and i2 are just reversed

You may specify a comparer IComparer implementation  as a parameter in Array Sort  the order of sorting actually depends on comparer  The default comparer is used in ascending sorting

Use LINQ OrderByDescending method  It returns IOrderedIEnumerable lt int gt   which you can convert back to Array if you need so  Generally  List lt  gt s are more functional then Arrays   array   array OrderByDescending c   gt  c  ToArray

For in-place sorting in descending order  int   numbers     1  2  3    Array Sort numbers   a  b    gt  b CompareTo a     For out-of-place sorting  no changes to input array   int   numbers     1  2  3    var sortedNumbers   numbers OrderByDescending x   gt  x  ToArray
