如何在 C# 中使用 Microsoft.Office.Interop.Excel 添加数据透视表过滤器

Question

我基于 Excel (.xlsx) 文件创建了一个数据透视表。该程序将字段添加到行、值和过滤器。使用 PivotFilters.Add2 会导致 0x800a03ec 错误，从而终止程序。如何正确使用PivotFilters.Add2？

我尝试过滤具有不同数据类型的不同字段。另外，我尝试使用Type.Missing 代替未使用的参数。对于 VB，似乎有很多关于这种方法的信息，但对于 C# 来说没有那么多。

过滤器中选择的项目应该在最后一行的两个日期之间。

    var xlApp = new Microsoft.Office.Interop.Excel.Application();
    xlApp.Visible = true;
    var workBook = xlApp.Workbooks.Open(spreadsheetLocation);
    var workSheet1 = (Microsoft.Office.Interop.Excel.Worksheet)workBook.Sheets["Data"];
    var workSheet2 = (Microsoft.Office.Interop.Excel.Worksheet)workBook.Sheets.Add();

    Microsoft.Office.Interop.Excel.Range last = workSheet1.Cells.SpecialCells(Microsoft.Office.Interop.Excel.XlCellType.xlCellTypeLastCell, Type.Missing);
    Microsoft.Office.Interop.Excel.Range range = workSheet1.get_Range("A1", last);

    Microsoft.Office.Interop.Excel.PivotCaches pivotCaches = null;
    Microsoft.Office.Interop.Excel.PivotCache pivotCache = null;
    Microsoft.Office.Interop.Excel.PivotTable pivotTable = null;
    Microsoft.Office.Interop.Excel.PivotFields pivotFields = null;
    Microsoft.Office.Interop.Excel.PivotField filterField = null;
    Microsoft.Office.Interop.Excel.PivotField accNumField = null;
    Microsoft.Office.Interop.Excel.PivotField amountPaidField = null;

    pivotCaches = workBook.PivotCaches();
    pivotCache = pivotCaches.Create(XlPivotTableSourceType.xlDatabase, range);

    pivotTable = pivotCache.CreatePivotTable(workSheet2.Cells[1,1]);
    pivotFields = (Microsoft.Office.Interop.Excel.PivotFields)pivotTable.PivotFields();
    amountPaidField = (Microsoft.Office.Interop.Excel.PivotField)pivotFields.Item("AmountPaid");
    amountPaidField.Orientation = Microsoft.Office.Interop.Excel.XlPivotFieldOrientation.xlDataField;
    amountPaidField.NumberFormat = "$#,###,###.00";

    accNumField = (Microsoft.Office.Interop.Excel.PivotField)pivotFields.Item("AccNumber");
    accNumField.Orientation = Microsoft.Office.Interop.Excel.XlPivotFieldOrientation.xlRowField;

    filterField = (Microsoft.Office.Interop.Excel.PivotField)pivotFields.Item("AccDate");
    filterField.Orientation = Microsoft.Office.Interop.Excel.XlPivotFieldOrientation.xlPageField;
    filterField.EnableMultiplePageItems = true;
    filterField.PivotFilters.Add2(XlPivotFilterType.xlDateBetween, Type.Missing, DateTime.Now.AddDays(-30), DateTime.Now.AddDays(-20));

Answer 2

正如 Asger 上面提到的，过滤器不能添加到页面字段中。相反，必须设置枢轴项的可见性属性。

var pivotItems = filterField.PivotItems();
DateTime date = Convert.ToDateTime(item.Name);
foreach (var item in pivotItems)
{
    item.Visible = false;
    if (date < DateTime.Now.AddDays(-30) || date > DateTime.Now.AddDays(-20))
    {
        item.Visible = true;
    }
}

找到几乎任何互操作问题的答案的最佳方法是记录一个宏，然后检查源代码。
