SortMerge(Object[],Object[],IComparer,Int32,Int32) Method

Sorts the passed in array based on the passed in comparer using a modified merge-sort algorithm. Optionally you can pass in a temporary array equal (or greater) in size to arr. The method will make use of that array instead of allocating one. If null is passed in, then it will allocate one. Merge sort should be used if the operation of comparing items is expensive.
