Missing Assembly Reference for OfficeMergeControlException

Question

When I try to use the code to combine multiple .docx files (the first listing at: Append multiple DOCX files together), I seem to be missing an assembly reference for OfficeMergeControlException.

I'm using .NET Framework 4.

Any ideas?

Thanks, Rich

Answer 1

There is no point throwing a custom Exception in that scenerio. Just throw an Exception

catch (Exception e)
{
    throw new Exception(string.Format(CultureInfo.CurrentCulture, "Error while merging files. Document index {0}", pointer), e);
}

Or better yet dont catch an exception at all. You are losing information by changing the exception type and formatting a message.

Seems to be a custom exception. Something like:

public class OfficeMergeControlException : Exception 
{
    public OfficeMergeControlException(string message, System.Exception innerException)  : base(message, innerException) { }
}
