本文介绍通过C#和VB.NET程序代码来创建和编辑PPT文档中的SmartArt图形。文中将分两个操作示例来演示创建和编辑结果。
使用工具：Spire.Presentation for .NET hotfix 5.9.5
Dll文件引用：
方式1：下载包。下载后，解压，打开Bin文件夹，根据自己用的.NET Framework选择相应的文件夹，如：此示例中使用的是NET4.0，即打开NET4.0文件，找到Spire.Presentation.dll文件。找到dll文件后，在vs程序中添加引用该dll。
如下引用结果：
方式2：通过Nuget搜索下载导入。
注：创建SmartArt图形时，可创建80多种不同类型的图形，编辑图形是，可添加、删除节点、编辑节点内容、给节点内容设置超链接（包括链接到网页、链接到幻灯片）
示例1. 创建PPT SmartArt图形
using Spire.Presentation; using Spire.Presentation.Diagrams; namespace AddSmartArt { class Program { static void Main(string[] args) { //实例化Presentation对象 Presentation ppt = new Presentation(); //设置幻灯片大小 ppt.SlideSize.Type = SlideSizeType.Screen16x9; //添加组织结构图类型的SmartArt图形，并指定位置、大小 ISmartArt smartArt = ppt.Slides[0].Shapes.AppendSmartArt(100, 50, 450, 250, SmartArtLayoutType.OrganizationChart); //设置SmartArt的样式和颜色 smartArt.Style = SmartArtStyleType.IntenceEffect; smartArt.ColorStyle = SmartArtColorType.ColorfulAccentColors3to4; //移除默认的形状(Node即代表SmartArt中的形状） foreach (ISmartArtNode node in smartArt.Nodes) { smartArt.Nodes.RemoveNode(node); } //添加形状并在其下面添加嵌套子形状 ISmartArtNode node1 = smartArt.Nodes.AddNode(); ISmartArtNode node1_1 = node1.ChildNodes.AddNode(); ISmartArtNode node1_1_1 = node1_1.ChildNodes.AddNode(); ISmartArtNode node1_1_2 = node1_1.ChildNodes.AddNode(); ISmartArtNode node1_1_3 = node1_1.ChildNodes.AddNode(); ISmartArtNode node1_1_4 = node1_1.ChildNodes.AddNode(); ISmartArtNode node1_1_5 = node1_1.ChildNodes.AddNode(); ISmartArtNode node1_1_6 = node1_1.ChildNodes.AddNode(); ISmartArtNode node1_1_1_1 = node1_1_1.ChildNodes.AddNode(); ISmartArtNode node1_1_1_2 = node1_1_1.ChildNodes.AddNode(); ISmartArtNode node1_1_1_3 = node1_1_1.ChildNodes.AddNode(); ISmartArtNode node1_1_3_1 = node1_1_3.ChildNodes.AddNode(); ISmartArtNode node1_1_3_2 = node1_1_3.ChildNodes.AddNode(); ISmartArtNode node1_1_6_1 = node1_1_6.ChildNodes.AddNode(); ISmartArtNode node1_1_6_2 = node1_1_6.ChildNodes.AddNode(); ISmartArtNode node1_1_6_3 = node1_1_6.ChildNodes.AddNode(); //在每一个形状上添加文字 node1.TextFrame.Text = "董事会n" + "Board of Directors"; node1_1.TextFrame.Text = "总经理n" + "General Manager"; node1_1_1.TextFrame.Text = "供应部n" + "Supply Dept."; node1_1_2.TextFrame.Text = "营销部n" + "Sales Dept."; node1_1_3.TextFrame.Text = "生产部n" + "Productive Dept."; node1_1_4.TextFrame.Text = "财务部n" + "Finance Dept."; node1_1_5.TextFrame.Text = "人力资源部n" + "HR Dept."; node1_1_6.TextFrame.Text = "质检中心n" + "Quality Center"; node1_1_1_1.TextFrame.Text = "采购部n" + "Purchase Dept."; node1_1_1_2.TextFrame.Text = "仓库管理n" + "Warehouse Manager"; node1_1_1_3.TextFrame.Text = "物流部n" + "Logistics Dept."; node1_1_3_1.TextFrame.Text = "生产车间n" + "Production Dept."; node1_1_3_2.TextFrame.Text = "维修部n" + "Maintenance Dept."; node1_1_6_1.TextFrame.Text = "生产质量管理n" + "Production Quality Mgt."; node1_1_6_2.TextFrame.Text = "生产安全管理n" + "Production Safety Mgt."; node1_1_6_3.TextFrame.Text = "环境管理n" + "Environmental Mgt."; //保存文档 ppt.SaveToFile("result.pptx", FileFormat.Pptx2013); System.Diagnostics.Process.Start("result.pptx"); } } }
图形创建结果：

示例2. 编辑PPT SmartArt图形
using Spire.Presentation; using Spire.Presentation.Diagrams; namespace ModifySmartArt { class Program { static void Main(string[] args) { //加载PPT幻灯片文档 Presentation ppt = new Presentation(); ppt.LoadFromFile("test.pptx"); //获取SmartArt图形的节点集合 ISmartArt smartart = ppt.Slides[0].Shapes[0] as ISmartArt; ISmartArtNodeCollection nodes = smartart.Nodes; //更改节点内容 nodes[1].TextFrame.Text = "新修改的节点内容"; //添加超链接到节点 nodes[2].Click = new ClickHyperlink("https://baike.baidu.com/");//添加指向网页的超链接 nodes[3].Click = new ClickHyperlink(ppt.Slides[1]);//添加指向指定幻灯片的超链接 //添加节点 ISmartArtNode newnode = nodes[5].ChildNodes.AddNode(); newnode.TextFrame.Text = "新添加的节点内容"; //删除节点 //nodes[0].ChildNodes[3].ChildNodes.RemoveNodeByPosition(0); //保存到本地并打开 ppt.SaveToFile("output.pptx", FileFormat.Pptx2010); System.Diagnostics.Process.Start("output.pptx"); } } }
添加超链接后，注意要在幻灯片播放下才可见超链接添加效果：
VB.NET
Imports Spire.Presentation Imports Spire.Presentation.Diagrams Namespace ModifySmartArt Class Program Private Shared Sub Main(args As String()) '加载PPT幻灯片文档 Dim ppt As New Presentation() ppt.LoadFromFile("test.pptx") '获取SmartArt图形的节点集合 Dim smartart As ISmartArt = TryCast(ppt.Slides(0).Shapes(0), ISmartArt) Dim nodes As ISmartArtNodeCollection = smartart.Nodes '更改节点内容 nodes(1).TextFrame.Text = "新修改的节点内容" '添加超链接到节点 nodes(2).Click = New ClickHyperlink("https://baike.baidu.com/") '添加指向网页的超链接 nodes(3).Click = New ClickHyperlink(ppt.Slides(1)) '添加指向指定幻灯片的超链接 '添加节点 Dim newnode As ISmartArtNode = nodes(5).ChildNodes.AddNode() newnode.TextFrame.Text = "新添加的节点内容" '删除节点 'nodes[0].ChildNodes[3].ChildNodes.RemoveNodeByPosition(0); '保存到本地并打开 ppt.SaveToFile("output.pptx", FileFormat.Pptx2010) System.Diagnostics.Process.Start("output.pptx") End Sub End Class End Namespace
