Ranorex Forum

Hi,

I have an issue I need to find a solution to: I need to click on a random directory : and afterwards click on a random file: How can I choose a random object with ranorex?

Thx!

Ranorex is built on .NET. You can use the .NET Random class to choose a number between 0 and 1 and then multiply by the number of items in the list. This will give you the zero-based index of the folder to pick. Then add 1 (XPath uses 1 based indexing) and store the result in a module variable. You can use that variable in your item's path like ".//element[$FolderIndex]".

I would like to add some hint on directories:
First make sure, that the proper dll-s are used:

using System;
using System.IO;

To count the numbers of directories in C:\ directory

int countDir = System.IO.Directory.GetDirectories.("C:\").Length;

To count the files in a directory:

string targetDirectory = "C:\";
string [] fileEntries = Directory.GetFiles(targetDirectory );
int countFiles = filEntries.Length;
