C＃如何在PowerPoint幻灯片中添加多个对象

Question

1）我必须在幻灯片的顶部中心位置显示一个文本

2）在文本下方，我必须在表中显示数据

3）我必须从存储在数据表中的数据在同一张幻灯片中生成折线图。

我正在寻找这种输出。 在这里，我分享一个屏幕截图。

在这里，我将分享我到目前为止的代码。

    pptNS.ApplicationClass powerpointApplication = null;
    pptNS.Presentation pptPresentation = null;
    pptNS.Slide pptSlide = null;
    pptNS.ShapeRange shapeRange = null;
    pptNS.Shape oShape = null;

    xlNS.ApplicationClass excelApplication = null;
    xlNS.Workbook excelWorkBook = null;
    xlNS.Worksheet targetSheet = null;
    xlNS.ChartObjects chartObjects = null;
    xlNS.ChartObject existingChartObject = null;
    xlNS.Range destRange = null;

    string paramPresentationPath = @"D:\test\Chart Slide.pptx";
    string paramWorkbookPath = @"D:\test\NPS.xlsx";
    object paramMissing = Type.Missing;


    try
    {
        // Create an instance of PowerPoint.
        powerpointApplication = new pptNS.ApplicationClass();

        // Create an instance Excel.          
        excelApplication = new xlNS.ApplicationClass();

        // Open the Excel workbook containing the worksheet with the chart
        // data.
        excelWorkBook = excelApplication.Workbooks.Open(paramWorkbookPath,
                        paramMissing, paramMissing, paramMissing,
                        paramMissing, paramMissing, paramMissing,
                        paramMissing, paramMissing, paramMissing,
                        paramMissing, paramMissing, paramMissing,
                        paramMissing, paramMissing);

        // Get the worksheet that contains the chart.
        targetSheet =
            (xlNS.Worksheet)(excelWorkBook.Worksheets["Spain"]);

        // Get the ChartObjects collection for the sheet.
        chartObjects =
            (xlNS.ChartObjects)(targetSheet.ChartObjects(paramMissing));



        // Create a PowerPoint presentation.
        pptPresentation = powerpointApplication.Presentations.Add(
                            Microsoft.Office.Core.MsoTriState.msoTrue);

        // Add a blank slide to the presentation.
        pptSlide =
            pptPresentation.Slides.Add(1, pptNS.PpSlideLayout.ppLayoutBlank);

        // capture range
        //var writeRange = targetSheet.Range["A1:B15"];
        destRange = targetSheet.get_Range("A1:B15");

        System.Array myvalues = (System.Array)destRange.Cells.Value;
        List<Tuple<string, string>> cellData = ConvertToStringArray(myvalues);

        int iRows = cellData.Count;
        int iColumns = 2;
        int row = 1;

        oShape = pptSlide.Shapes.AddTable(iRows, iColumns, 500, 110, 160, 120);

        foreach (Tuple<string, string> item in cellData)
        {
            string strdate = item.Item1;
            string strValue = item.Item2;

            oShape.Table.Cell(row, 1).Shape.TextFrame.TextRange.Text = strdate;
            oShape.Table.Cell(row, 1).Shape.TextFrame.TextRange.Font.Name = "Verdana";
            oShape.Table.Cell(row, 1).Shape.TextFrame.TextRange.Font.Size = 8;
            oShape.Table.Cell(row, 1).Shape.Fill.BackColor.RGB = System.Drawing.Color.FromArgb(255, 0, 0).ToArgb(); 
            oShape.Table.Cell(row, 1).Shape.Fill.Visible = Microsoft.Office.Core.MsoTriState.msoTrue;

            oShape.Table.Cell(row, 2).Shape.TextFrame.TextRange.Text = (strValue.StartsWith("0") ?  "0%" : (strValue + "0%"));
            oShape.Table.Cell(row, 2).Shape.TextFrame.TextRange.Font.Name = "Verdana";
            oShape.Table.Cell(row, 2).Shape.TextFrame.TextRange.Font.Size = 8;


            row++;
        }

        oShape.Top = 10;
        oShape.Left =10;

        //copy range
        //destRange.Copy();

        // Paste the chart into the PowerPoint presentation.
        //shapeRange = pptSlide.Shapes.Paste();

        //var table = pptSlide.Shapes.AddTable();
        // Position the chart on the slide.
        //shapeRange.Left = 60;
        //shapeRange.Top = 100;

        // Get or capture the chart to copy.
        //existingChartObject = (xlNS.ChartObject)(chartObjects.Item(1));


        // Copy the chart from the Excel worksheet to the clipboard.
        //existingChartObject.Copy();

        // Paste the chart into the PowerPoint presentation.
        //shapeRange = pptSlide.Shapes.Paste();
        //Position the chart on the slide.
        //shapeRange.Left = 90;
        //shapeRange.Top = 100;

        // Save the presentation.
        pptPresentation.SaveAs(paramPresentationPath,
                        pptNS.PpSaveAsFileType.ppSaveAsOpenXMLPresentation,
                        Microsoft.Office.Core.MsoTriState.msoTrue);
    }
    catch (Exception ex)
    {
        Console.WriteLine(ex.Message);
    }
    finally
    {
        // Release the PowerPoint slide object.
        shapeRange = null;
        pptSlide = null;

        // Close and release the Presentation object.
        if (pptPresentation != null)
        {
            pptPresentation.Close();
            pptPresentation = null;
        }

        // Quit PowerPoint and release the ApplicationClass object.
        if (powerpointApplication != null)
        {
            powerpointApplication.Quit();
            powerpointApplication = null;
        }

        // Release the Excel objects.
        targetSheet = null;
        chartObjects = null;
        existingChartObject = null;

        // Close and release the Excel Workbook object.
        if (excelWorkBook != null)
        {
            excelWorkBook.Close(false, paramMissing, paramMissing);
            excelWorkBook = null;
        }

        // Quit Excel and release the ApplicationClass object.
        if (excelApplication != null)
        {
            excelApplication.Quit();
            excelApplication = null;
        }

        GC.Collect();
        GC.WaitForPendingFinalizers();

    }
}

1）问题是我不知道如何以编程方式在幻灯片的顶部中心添加自己的文本？

2）这样，我添加了一张表格来滑动我的数据。 这是代码

        List<Tuple<string, string>> cellData = ConvertToStringArray(myvalues);

        int iRows = cellData.Count;
        int iColumns = 2;
        int row = 1;

        oShape = pptSlide.Shapes.AddTable(iRows, iColumns, 500, 110, 160, 120);

        foreach (Tuple<string, string> item in cellData)
        {
            string strdate = item.Item1;
            string strValue = item.Item2;

            oShape.Table.Cell(row, 1).Shape.TextFrame.TextRange.Text = strdate;
            oShape.Table.Cell(row, 1).Shape.TextFrame.TextRange.Font.Name = "Verdana";
            oShape.Table.Cell(row, 1).Shape.TextFrame.TextRange.Font.Size = 8;
            oShape.Table.Cell(row, 1).Shape.Fill.BackColor.RGB = System.Drawing.Color.FromArgb(255, 0, 0).ToArgb(); 
            oShape.Table.Cell(row, 1).Shape.Fill.Visible = Microsoft.Office.Core.MsoTriState.msoTrue;

            oShape.Table.Cell(row, 2).Shape.TextFrame.TextRange.Text = (strValue.StartsWith("0") ?  "0%" : (strValue + "0%"));
            oShape.Table.Cell(row, 2).Shape.TextFrame.TextRange.Font.Name = "Verdana";
            oShape.Table.Cell(row, 2).Shape.TextFrame.TextRange.Font.Size = 8;


            row++;
        }

        oShape.Top = 10;
        oShape.Left =10;

3）现在我必须将折线图添加到幻灯片中，数据存储在数据表中，但是我不知道如何将折线图添加到幻灯片中。

所以请有人帮我完成编码。

谢谢

您正在寻找将形状添加到幻灯片。 我看到您在哪里创建形状，但从未添加它们。 以下是先前有关添加图表和标题的几个问题。 希望它能有所帮助，并祝您好运。
