MS PowerPoint演示文稿允许您创建包含文本,图像,图表,动画和其他元素的幻灯片放映。各种其他格式设置选项使您的演示文稿更具吸引力。在本文中,您将了解如何以编程方式创建此类演示文稿。您将学习如何使用C#创建具有文本,表格,图像和图表的PPTX演示文稿。

让我们开始使用Aspose.Slides for .NET创建一个空的PowerPoint演示文稿。以下是执行此操作的步骤。
下面的代码示例演示如何在C#中创建PowerPoint演示文稿。
// Instantiate a Presentation object that represents a presentation file using (Presentation presentation = new Presentation()) { // Get the first slide ISlide slide = presentation.Slides[0]; // Add content to slide... // Save presentation presentation.Save("NewPresentation.pptx", SaveFormat.Pptx); }
无需付出额外的努力即可打开现有的PowerPoint演示文稿。只需将PPTX文件的路径提供给Presentation类的构造函数,即可完成。下面的代码示例演示如何打开现有的PPTX演示文稿。
// Opening the presentation file by passing the file path to the constructor of Presentation class Presentation pres = new Presentation("OpenPresentation.pptx"); // Printing the total number of slides in the presentation System.Console.WriteLine(pres.Slides.Count.ToString());
创建演示文稿后,就可以开始向其中添加幻灯片了。以下是使用Aspose.Slides for .NET在演示文稿中添加幻灯片的步骤。
下面的代码示例演示如何使用C#在PowerPoint演示文稿中添加幻灯片。
// Instantiate Presentation class that represents the presentation file using (Presentation pres = new Presentation()) { // Instantiate SlideCollection calss ISlideCollection slds = pres.Slides; for (int i = 0; i < pres.LayoutSlides.Count; i++) { // Add an empty slide to the Slides collection slds.AddEmptySlide(pres.LayoutSlides[i]); } // Save the PPTX file to the Disk pres.Save("EmptySlide_out.pptx", SaveFormat.Pptx); }
现在,我们可以将内容添加到PowerPoint演示文稿的幻灯片中。首先,使用以下步骤向幻灯片添加一段文字。
下面的代码示例演示如何使用C#在幻灯片中添加文本。
// Instantiate PresentationEx// Instantiate PresentationEx using (Presentation pres = new Presentation()) { // Get the first slide ISlide sld = pres.Slides[0]; // Add an AutoShape of Rectangle type IAutoShape ashp = sld.Shapes.AddAutoShape(ShapeType.Rectangle, 150, 75, 150, 50); // Add TextFrame to the Rectangle ashp.AddTextFrame(" "); // Accessing the text frame ITextFrame txtFrame = ashp.TextFrame; // Create the Paragraph object for text frame IParagraph para = txtFrame.Paragraphs[0]; // Create Portion object for paragraph IPortion portion = para.Portions[0]; // Set Text portion.Text = "Aspose TextBox"; // Save the presentation to disk pres.Save("presentation.pptx", Aspose.Slides.Export.SaveFormat.Pptx); }
.NET的Aspose.Slides提供了一种在演示文稿文档中创建表的简便方法。以下是其步骤。
下面的代码示例演示如何在PowerPoint演示文稿幻灯片中创建表。
// Instantiate Presentation class that represents PPTX file Presentation pres = new Presentation(); // Access first slide ISlide sld = pres.Slides[0]; // Define columns with widths and rows with heights double[] dblCols = { 50, 50, 50 }; double[] dblRows = { 50, 30, 30, 30, 30 }; // Add table shape to slide ITable tbl = sld.Shapes.AddTable(100, 50, dblCols, dblRows); // Set border format for each cell for (int row = 0; row < tbl.Rows.Count; row++) { for (int cell = 0; cell < tbl.Rows[row].Count; cell++) { tbl.Rows[row][cell].CellFormat.BorderTop.FillFormat.FillType = FillType.Solid; tbl.Rows[row][cell].CellFormat.BorderTop.FillFormat.SolidFillColor.Color = Color.Red; tbl.Rows[row][cell].CellFormat.BorderTop.Width = 5; tbl.Rows[row][cell].CellFormat.BorderBottom.FillFormat.FillType = (FillType.Solid); tbl.Rows[row][cell].CellFormat.BorderBottom.FillFormat.SolidFillColor.Color= Color.Red; tbl.Rows[row][cell].CellFormat.BorderBottom.Width =5; tbl.Rows[row][cell].CellFormat.BorderLeft.FillFormat.FillType = FillType.Solid; tbl.Rows[row][cell].CellFormat.BorderLeft.FillFormat.SolidFillColor.Color =Color.Red; tbl.Rows[row][cell].CellFormat.BorderLeft.Width = 5; tbl.Rows[row][cell].CellFormat.BorderRight.FillFormat.FillType = FillType.Solid; tbl.Rows[row][cell].CellFormat.BorderRight.FillFormat.SolidFillColor.Color = Color.Red; tbl.Rows[row][cell].CellFormat.BorderRight.Width = 5; } } // Merge cells 1 & 2 of row 1 tbl.MergeCells(tbl.Rows[0][0], tbl.Rows[1][1], false); // Add text to the merged cell tbl.Rows[0][0].TextFrame.Text = "Merged Cells"; // Save PPTX to Disk pres.Save("table.pptx", SaveFormat.Pptx);
以下是使用C#在PowerPoint演示文稿中添加图表的步骤。
下面的代码示例演示如何使用C#在演示文稿中添加图表。
// Instantiate Presentation class that represents PPTX file Presentation pres = new Presentation(); // Access first slide ISlide sld = pres.Slides[0]; // Add chart with default data IChart chart = sld.Shapes.AddChart(ChartType.ClusteredColumn, 0, 0, 500, 500); // Setting chart Title // Chart.ChartTitle.TextFrameForOverriding.Text = "Sample Title"; chart.ChartTitle.AddTextFrameForOverriding("Sample Title"); chart.ChartTitle.TextFrameForOverriding.TextFrameFormat.CenterText = NullableBool.True; chart.ChartTitle.Height = 20; chart.HasTitle = true; // Set first series to Show Values chart.ChartData.Series[0].Labels.DefaultDataLabelFormat.ShowValue = true; // Setting the index of chart data sheet int defaultWorksheetIndex = 0; // Getting the chart data worksheet IChartDataWorkbook fact = chart.ChartData.ChartDataWorkbook; // Delete default generated series and categories chart.ChartData.Series.Clear(); chart.ChartData.Categories.Clear(); int s = chart.ChartData.Series.Count; s = chart.ChartData.Categories.Count; // Adding new series chart.ChartData.Series.Add(fact.GetCell(defaultWorksheetIndex, 0, 1, "Series 1"), chart.Type); chart.ChartData.Series.Add(fact.GetCell(defaultWorksheetIndex, 0, 2, "Series 2"), chart.Type); // Adding new categories chart.ChartData.Categories.Add(fact.GetCell(defaultWorksheetIndex, 1, 0, "Caetegoty 1")); chart.ChartData.Categories.Add(fact.GetCell(defaultWorksheetIndex, 2, 0, "Caetegoty 2")); chart.ChartData.Categories.Add(fact.GetCell(defaultWorksheetIndex, 3, 0, "Caetegoty 3")); // Take first chart series IChartSeries series = chart.ChartData.Series[0]; // Now populating series data series.DataPoints.AddDataPointForBarSeries(fact.GetCell(defaultWorksheetIndex, 1, 1, 20)); series.DataPoints.AddDataPointForBarSeries(fact.GetCell(defaultWorksheetIndex, 2, 1, 50)); series.DataPoints.AddDataPointForBarSeries(fact.GetCell(defaultWorksheetIndex, 3, 1, 30)); // Setting fill color for series series.Format.Fill.FillType = FillType.Solid; series.Format.Fill.SolidFillColor.Color = Color.Red; // Take second chart series series = chart.ChartData.Series[1]; // Now populating series data series.DataPoints.AddDataPointForBarSeries(fact.GetCell(defaultWorksheetIndex, 1, 2, 30)); series.DataPoints.AddDataPointForBarSeries(fact.GetCell(defaultWorksheetIndex, 2, 2, 10)); series.DataPoints.AddDataPointForBarSeries(fact.GetCell(defaultWorksheetIndex, 3, 2, 60)); // Setting fill color for series series.Format.Fill.FillType = FillType.Solid; series.Format.Fill.SolidFillColor.Color = Color.Green; // First label will be show Category name IDataLabel lbl = series.DataPoints[0].Label; lbl.DataLabelFormat.ShowCategoryName = true; lbl = series.DataPoints[1].Label; lbl.DataLabelFormat.ShowSeriesName = true; // Show value for third label lbl = series.DataPoints[2].Label; lbl.DataLabelFormat.ShowValue = true; lbl.DataLabelFormat.ShowSeriesName = true; lbl.DataLabelFormat.Separator = "/"; // Save presentation with chart pres.Save("AsposeChart_out.pptx", SaveFormat.Pptx);
以下代码示例显示了如何在演示幻灯片中添加SVG图像。
下面的代码示例演示如何在C#中向演示文稿添加图像。
// Create presentation using (var p = new Presentation()) { // Read image var svgContent = File.ReadAllText("image.svg"); // Add image to image collection var emfImage = p.Images.AddFromSvg(svgContent); // Add image to slide p.Slides[0].Shapes.AddPictureFrame(ShapeType.Rectangle, 0, 0, emfImage.Width, emfImage.Height, emfImage); // Save presentation p.Save("presentation.pptx", SaveFormat.Pptx); }
