写入Excel文件错误

Question

So I'm attempting to write a big ol' bunch of records I pulled out of an SQL database and sorted to an excel document using C#.

The problem I'm having is it works fine for exactly 207159 rows. Any more than that and it throws up an error, 0x800A03EC

Clearly it's not getting stuck on the old Excel row limit. Clearly it's not getting stuck on the new Excel row limit. I'm completely stumped on this one!

I have somewhere in the region of 350 000 records to write to an Excel document.

The error is occurring during the call to set the value of the range property of the sheet. It won't do it when it is higher than the particular number I am passing to it. Any suggestions?

UPDATE:

I solved this by calling the ToShortDateString() method of DateTime. It didn't like the time element of the DateTime. Strange really as the time was always 00:00:00

Answer 1

I've recently created a report that outputs to excel and came accross a similar issue before.

The error code 0x800A03EC (or -2146827284) means NAME_NOT_FOUND; you've asked for something, and Excel can't find it.

Hopefully the code I came up with to solve a similar issue can be of some assistance to you.

                    try
                    {

                     //MyData

                    catch (Exception COMException_HRESULT)
                    {
                        Console.Write(" 0x800AC472 is the VBA_E_IGNORE error that is returned whenever an object model call is invoked while the property browser is suspended.", COMException_HRESULT);

                    }

Answer 2

Is the 207159 row always the same or is it a different row? On that had the same problem: HRESULT: 0x800A03EC on Worksheet.range

Answer 3

Used ToShortDateString() method of DateTime. The problem was the time element of the datetime, which it didn't like for some reason
