I am working with Window Service project. that have to write data to a sheet in Excel file in a sequence times.

但有時，只是有時，服務(wù)在嘗試使用單元格名稱獲取范圍時拋出異常Exception from HRESULT: 0x800A03EC".

But sometimes, just sometimes, the service throw out the exception "Exception from HRESULT: 0x800A03EC" while it's trying to get range with cell's name.

我已經(jīng)把打開excel表格的代碼放在這里了.

protected object m_MissingValue = System.Reflection.Missing.Value;
Range range = m_WorkSheet.get_Range(cell.CellName, m_MissingValue);

推薦答案

錯誤碼0x800A03EC(或-2146827284)表示NAME_NOT_FOUND；換句話說，你已經(jīng)要求了一些東西，而 Excel 找不到它.

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

這是一個通用代碼，它可以應(yīng)用于很多它找不到的東西，例如.當(dāng) PivotItem 未應(yīng)用過濾器時，使用當(dāng)時無效的屬性(如 PivotItem.SourceNameStandard)會拋出此錯誤.Worksheets["BLAHBLAH"] 在工作表不存在等情況下會拋出此錯誤.通常，您要求的是具有特定名稱且不存在的內(nèi)容.至于為什么，這需要你自己去挖掘.

This is a generic code, which can apply to lots of things it can't find e.g. using properties which aren't valid at that time like PivotItem.SourceNameStandard throws this when a PivotItem doesn't have a filter applied. Worksheets["BLAHBLAH"] throws this, when the sheet doesn't exist etc. In general, you are asking for something with a specific name and it doesn't exist. As for why, that will taking some digging on your part.

檢查您的工作表是否確實有您要求的范圍，或者 .CellName 肯定會返回您要求的范圍的名稱.

Check your sheet definitely does have the Range you are asking for, or that the .CellName is definitely giving back the name of the range you are asking for.
