我有一个包含多个图表的Excel工作簿。我创建了一个for循环来获取每张表中的图表。这没有错误。
我遇到的问题是我无法导入多个图表,只能导入一个图表而导入的图片不是图表。
当我尝试导入多个图表时,我会在此行中获得COMException
:
objChart.Copy();
完整错误:
An exception of type 'System.Runtime.InteropServices.COMException' occurred in mscorlib.dll but was not handled in user code
Additional information: Exception from HRESULT: 0x800A03EC
这是我的完整方法:
public int ImportExcelChartsFromWorkbookToSlides(int startingSlideIndex, string workbookPath, string[] slideTitles)
{
int slideIndex = startingSlideIndex;
int titleIndex = 0;
EXCL.Application objExclApp = new EXCL.Application();
EXCL.Workbook objWorkbook = objExclApp.Workbooks.Open(workbookPath, Editable: false);
foreach (EXCL.Worksheet objSheet in objWorkbook.Worksheets)
{
foreach (EXCL.ChartObject objChart in objSheet.ChartObjects())
{
AddTitleOnlySlide(slideIndex);
SetTitleOnlySlideTitle(slideTitles[titleIndex]);
// Copy Chart from Sheet to Slide
objChart.Copy();
PPT.ShapeRange objShapeRange = objSlide.Shapes.Paste();
// TODO PARAMETER
objShapeRange.Left = 10;
objShapeRange.Top = 100;
slideIndex++;
titleIndex++;
}
}
return slideIndex;
}
是否有人发现此代码存在任何问题?
更新
如果我更改此行:
objChart.Copy();
到此:
objChart.CopyPicture();
我没有问题。可能导致这种情况的原因是什么?
答案 0 :(得分:0)
我设法使用objChart.CopyPicture();
解决了这个问题,但对于某些用户来说这是causing crashes,所以我最终这样做了:
string chartPath = $@"{workbookPath.Substring(0, workbookPath.LastIndexOf("\\") + 1)}{DateTime.Now.Ticks}.png";
objChart.Chart.Export(chartPath, "PNG", false);
objSlide.Shapes.AddPicture2(chartPath, MsoTriState.msoFalse, MsoTriState.msoTrue, chartPosLeft, chartPosTop, compress: MsoPictureCompress.msoPictureCompressFalse);
