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");
}
}
}

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
