Cannot get PartsList

[1354448288]

Here is my code:

PartsList partsList = drawingDocument.ActiveSheet.PartsLists[1];

When I continue:

MessageBox.Show(partsList.PartsListRows[0].ReferencedFiles[0].ToString());

I cannot get anything, and will get a message(an exception)

◢

$exception

HRESULT:0x80070057 (E_INVALIDARG))

System.ArgumentException

First item in collections in Inventor has index 1

MessageBox.Show(partsList.PartsListRows[1].ReferencedFiles[1].ToString());

I explained the exception a wrong way. The real problem is that :
PartsList partsList = drawingDocument.ActiveSheet.PartsLists[1];
int num = partsList.MaximumRows;
Then, I get a message: exception from HRESULT:0x80004005 (E_FAIL))

I indeed get the partlist, and can print partslist.title partslist.layer, but I cannot get partsList.MaximumRows

OK this member returns exception but you can use another approach

var partsList = drawing.ActiveSheet.PartsLists[1];
int rowsCount = partsList.PartsListRows.Count;

foreach (PartsListRow row in partsList.PartsListRows)
{
    string displayName = row.ReferencedFiles[1].DisplayName;
    //Logger.Debug(displayName);
}

Thank you !! I just found the same way.
But I am still curious about why cannot get partsList.MaximumRows.

 I expect that partsList.MaximumRows is a reference to the maximum number of rows before a new column  is added to your part list.
