Adding formula to cell Exception from HRESULT: 0x800A03EC

问题

I'm trying to add a formula to cell but i got the error Exception from HRESULT: 0x800A03EC There are lots of posts with similar issues however none could help me plus i'm not doing any fancy formula's what i'm doing wrong?

 Thread.CurrentThread.CurrentCulture =
 new System.Globalization.CultureInfo("en-US");
 workbook = application.Workbooks.Open(Helper.GetLocalInstalationFolder() +
             @"\IMC.xltx", 0, false, 5, "", "", true, XlPlatform.xlWindows, "\t", false,
                                                       false, 0, true, 1, 0);
 worksheet = workbook.Worksheets["Report"];
 var rowValue = 0;
 for (int i = 2; i <= LastRow; i++)
 {
     rowValue = i - 1;
     for (int j = 1; j <= 37; j++)
     {
          worksheet.Cells[i, j] = MyArray[rowValue, j];

     }
     // I tried all the following all give the same exception:
     worksheet.Range[i, 38].Formula = "=3+4"; 
     worksheet.get_Range("R" + i + "C38").FormulaR1C1 = "=3+4";
     worksheet.Range[i, 38].FormulaR1C1 = "=3+4";
     worksheet.get_Range("R" + i + "C38").Formula = "=3+4";
   }

回答1:

It is a crappy exception and doesn't mean anything more than you slamming Excel with processing requests at a rate that it cannot keep up with. Your program essentially looks like a hyper-active user that's entering formulas at a rate of one per microsecond.

The workaround is to go slower by intentionally sleeping or to force Excel to do less work. You will very probably fix it in this case by assigning the Application.Calculation property. Set it to manual before you start putting formulas into cells. And back to auto after you're done.

Perhaps this brings you into the right direction->

回答3:

in my case I was missing double-quotes in the HYPERLINK formula arguments, i.e. the formula itself was wrong. i tried a valid formula, like ..Cell(x,y).Formula = "=MIN(2)" and it worked, therefore that was the case..
