Yuri,
I have not found an easy way to sort a 2 dim array natively with .NET but there is an interesting overload method of Array.Sort() that might assist you. Here is some quick code to show how it works(the example in the docs is also good)

			string[] sa = new string[5];
			sa[0] = @"c:\it\a.bak";
			sa[1] = @"c:\it\e.bak";
			sa[2] = @"c:\it\c.bak";
			sa[3] = @"c:\it\b.bak";
			sa[4] = @"c:\it\d.bak";

			string[] sb = new string[5];
			sb[0] = "20050604";
			sb[1] = "20050602";
			sb[2] = "20050609";
			sb[3] = "20040604";
			sb[4] = "20050704";

			MessageBox.Show(sb[0]+":"+sa[0]+"\n"+sb[1]+":"+sa[1]+"\n"+sb[2]+":"+sa[2]+"\n"+sb[3]+":"+sa[3]+"\n"+sb[4]+":"+sa[4],"before");
			
			// sort each array idependently
			//Array.Sort(sa);
			//Array.Sort(sb);

			// "link" the arrays using an overload method
			Array.Sort(sb,sa);
			
			MessageBox.Show(sb[0]+":"+sa[0]+"\n"+sb[1]+":"+sa[1]+"\n"+sb[2]+":"+sa[2]+"\n"+sb[3]+":"+sa[3]+"\n"+sb[4]+":"+sa[4],"after");

Hope this helps.

PS. in order to sort an array the array needs to be traversed (even in vfp) so even if you want to sort the array so you can to a while loop all the elements of the array has to be examined. <bg>
