C#VSTO : Coloring pivottable cells

Question

您好，我正在尝试为数据透视表添加一些代码颜色。 它可以很好地为单元格着色，但如果我刷新表格，所有颜色都会消失，就好像这些颜色没有正确附加到数据透视表一样。

我有以下代码(这是从一个更大的代码中截取的):

myPivotTable.PivotSelect("'" + item["Name"].ToString() + "'[All;Total]", XlPTSelectionMode.xlDataAndLabel, true);

((Range)Globals.ThisWorkbook.Application.Selection).Interior.Color = 15962653;

我试过在 VB 的 Excel 中做一个宏，当它运行时，它工作得很好，所以我不明白为什么 C# VSTO 不能工作...

ActiveSheet.PivotTables("PivotTable1").PivotSelect "'ItemName'[All;Total]", xlDataAndLabel, True

Selection.Interior.Color = 15962653

非常感谢您的帮助:)

这里有更多的代码。 BaseVars.GlobalWB 是一个引用事件工作簿 (Globals.ThisWorkBook) 的变量。这使得同时使用 2 个 Excel 成为可能，而 VSTO 不会在错误的工作簿上运行代码。

foreach (DataRow item in myPivotTableFields.Tables[0].Rows)
        {
// Field name from data sheet
            myPivotField = (PivotField)myPivotFields.Item(item["Name"].ToString());
            // Field name in the pivot table
            myPivotField.Caption = item["Caption"].ToString();
            // Their subtotal value
            myPivotField.set_Subtotals(Type.Missing, GenerateSubTotalArray(item["SubTotal"].ToString()));

            #region Attribs

            //Include new items in manual filter
            if (item["Attrib01"].ToString() == "True")
            {
                myPivotField.IncludeNewItemsInFilter = true;
            }
            else
            {
                myPivotField.IncludeNewItemsInFilter = false;
            }

            // Show items labels in outline form
            if (item["Attrib02"].ToString() == "Outline")
            {
                myPivotField.LayoutForm = XlLayoutFormType.xlOutline;
            }
            else
            {
                myPivotField.LayoutForm = XlLayoutFormType.xlTabular;
            }

            // Display labels from the next field in the same column
            if (item["Attrib03"].ToString() == "True")
            {
                myPivotField.LayoutCompactRow = true;
            }
            else
            {
                myPivotField.LayoutCompactRow = false;
            }

            // Display subtotals at the top of each group
            if (item["Attrib04"].ToString() == "AtBottom")
            {
                myPivotField.LayoutSubtotalLocation = XlSubtototalLocationType.xlAtBottom;
            }
            else
            {
                myPivotField.LayoutSubtotalLocation = XlSubtototalLocationType.xlAtTop;
            }

            // Insert blank line after each item label
            if (item["Attrib05"].ToString() == "True")
            {
                myPivotField.LayoutBlankLine = true;

如果您使用的是 C# VSTO，请不要使用 Selection.Interior.Color。请改用 Selection.Interior.ColorIndex。 Excel 使用 56 色调色板，您在 C# 中指定的任何颜色都将“转换”为其中一种调色板颜色。有效的 ColorIndex 值介于 1 和 56 之间。另请查看有关调色板和 Excel 的有用引用。
