The CompoundDocumentHeaderException is thrown when a file being loaded is not a valid Microsoft Project file. Below are the steps to effectively handle this exception using Aspose.Tasks:

Step 1: Try-Catch Block

Enclose the code that may potentially throw the CompoundDocumentHeaderException within a try-catch block.

try
{
    // Load the project file
    var project = new Project(DataDir + "Project1.mpp");

    // Display project name
    Console.WriteLine("Project Name: " + project.Get(Prj.Name));
}
catch (CompoundDocumentHeaderException e)
{
    // Catch and handle the exception
    Console.WriteLine(e.Message);
}

Step 2: Load Project File

Load the project file using the Project class provided by Aspose.Tasks.

Step 3: Display Project Information

Access any required project information, such as the project name, using appropriate methods or properties.

Step 4: Exception Handling

In case the CompoundDocumentHeaderException occurs during project loading, handle it within the catch block. Print or log the exception message for further analysis.

Conclusion

In conclusion, handling exceptions like CompoundDocumentHeaderException is crucial for robust .NET application development. With Aspose.Tasks for .NET, developers can effectively manage such exceptions and ensure smooth execution of project management tasks.
