Question

我想将Cell格式/样式复制到另一个单元格就像Excel应用程序中的“Format Painter”选项一样

这是我尝试但没有工作的

Microsoft.Office.Interop.Excel.Style HeaderStyle = null;

SxlSheetRange = (Microsoft.Office.Interop.Excel.Range)xlTamplateWorkSheet.UsedRange[rowCnt, colCnt];
DxlSheetRange = (Microsoft.Office.Interop.Excel.Range)xlTamplateWorkSheet.UsedRange[DrowCnt, DcolCnt];

HeaderStyle = SxlSheetRange.Style;

DxlSheetRange.Style = HeaderStyle;

我不想复制只想像Excel中的“格式画家”选项那样设置单元格样式。

Answer 1

我认为你所追求的是PasteSpecial方法。例如：

//Copies cell C3
Range cellToCopy = (Range)activeWorksheet.Cells[3, 3];
cellToCopy.Copy();

//Paste format only to the cell C5
Range cellToPaste = (Range)activeWorksheet.Cells[5, 3];
cellToPaste.PasteSpecial(XlPasteType.xlPasteFormats);

*提示：您可以在Excel上录制宏并查看宏的代码并在C＃中使用该代码逻辑

这是一种解决方法，以XML格式读取和写入值（包括样式）。您需要扩展它以使其处理大于一个单元格的范围，但请将其视为概念证明：

                var workbook = app.ActiveWorkbook;
                var sheet = (Excel.Worksheet)workbook.ActiveSheet;

                var range1 = sheet.Cells[1, 1];
                var range2 = sheet.Cells[1, 3];

                //our range is only 1 cell in this case, so we get the first cell and its style

            using (var writer = new StringWriter(builder))
