Open password protected project over FileStream


is it possible to open password protected project using FileStream?
Using simple code:

public void OpenProject()


System.IO.FileStream fs = new System.IO.FileStream("PassOpen.mpp", System.IO.FileMode.Open);



Project doc = new Project(fs, “open”);

if (doc != null)


Console.WriteLine("Pass OK");



catch (Exception ex)




fs = null;


I am getting: "Project reading exception".

Sample project is attached.

Btw. I tried also to use String pass instead of "open" but same problem.

Hi Oliver,

Thank you for contacting Aspose support team.

This scenario is tested by opening a password protected file using Aspose.Tasks for .NET 8.8.1. It is observed that it raises exception and is logged under Id:TASKS-34243 for further investigation by the product team. I shall write here as soon as some feedback is received in this regard.
