Excel VSTO + C# .NET + 創建數據透視表

Question

我正在嘗試通過 C# .Net 為 Excel VSTO 創建一個數據透視表，但不斷拋出一個異常，指出：

HRESULT 異常：0x800A03EC

我正在嘗試創建數據透視表的工作表稱為 oSheet 並且與具有源數據的工作表相同

我為數據透視表源創建了一個范圍：

Excel.Range pivotData = osheet.Range["A1", "B3"];

數據透視表所在的范圍：

Excel.Range pivotDest = osheet.Range["A12", "B14"];

然后嘗試用這個創建表：

osheet.PivotTableWizard(
              Excel.XlPivotTableSourceType.xlDatabase, 
              pivotData, 
              pivotDest, 
              "Table", 
              true, 
              true, 
              true, 
              true, 
              true, 
              true, 
              false, 
              false, 
              Excel.XlOrder.xlDownThenOver, 
              0, 
              false, 
              false
);

錯誤發生在表向導行中。

關於導致錯誤的原因或通過 C# .Net 創建數據透視表的更好方法的任何想法？

完整代碼

Excel.Application oApp;
Excel.Worksheet osheet;
Excel.Workbook oBook;

oApp = new Excel.Application();
oBook = oApp.Workbooks.Add();
osheet = (Excel.Worksheet)oBook.Worksheets.get_Item(1);

osheet.Cells[1, 1] = "Name";
osheet.Cells[1, 2] = "Salary";

osheet.Cells[2, 1] = "Frank";
osheet.Cells[2, 2] = 1500000;

osheet.Cells[3, 1] = "Millford";
osheet.Cells[3, 2] = 2200;

//Now capture range of first sheet = I will need this to create pivot table
Excel.Range oRange = osheet.Range["A1", "B3"];


var pch = oBook.PivotCaches();

Excel.Range pivotData = osheet.Range["A1", "B3"];

Excel.PivotCache pc = pch.Create(XlPivotTableSourceType.xlDatabase, pivotData);
Excel.PivotTable pvt = pc.CreatePivotTable(osheet.Range["A12"], "MyPivotTable");

pvt.PivotFields("Col1").Orientation = XlPivotFieldOrientation.xlRowField;
pvt.PivotFields("Col2").Orientation = XlPivotFieldOrientation.xlColumnField;
pvt.AddDataField(pvt.PivotFields("Col3"), "Sum of Col3", XlConsolidationFunction.xlSum);

Answer 1

前幾天剛回答了一個類似的問題...

https://stackoverflow.com/a/39968355/1278553

簡而言之，在 C# 中創建數據透視表的方法是：

Excel.Range pivotData = osheet.Range["A1", "B3"];

Excel.PivotCache pc = pch.Create(XlPivotTableSourceType.xlDatabase, pivotData);
Excel.PivotTable pvt = pc.CreatePivotTable(osheet.Range["A12"], "MyPivotTable");

然后分配您的行/列和數據字段：

pvt.PivotFields("Col1").Orientation = XlPivotFieldOrientation.xlRowField;
pvt.PivotFields("Col2").Orientation = XlPivotFieldOrientation.xlColumnField;
pvt.AddDataField(pvt.PivotFields("Col3"), "Sum of Col3", XlConsolidationFunction.xlSum);

我從我之前的答案中大量抄襲。

根據您更新的代碼，現在應該可以創建數據透視表：

var pch = oBook.PivotCaches();

Excel.Range pivotData = osheet.Range["A1", "B3"];

Excel.PivotCache pc = pch.Create(Excel.XlPivotTableSourceType.xlDatabase, pivotData);
Excel.PivotTable pvt = pc.CreatePivotTable(osheet.Range["A12"], "MyPivotTable");

pvt.PivotFields("Name").Orientation = Excel.XlPivotFieldOrientation.xlRowField;
pvt.AddDataField(pvt.PivotFields("Salary"), "Total Salary",
    Excel.XlConsolidationFunction.xlSum);
