刚好有个博文有代码介绍连接两个矩形: http://blog.csdn.net/namespace20100823/article/details/7338628 using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Text; using System.Windows.Forms; using Microsoft.Office.Interop.Visio;namespace 连线测试 { public partial class Form1 : Form { private Page m_page; private Master m_master; private Document m_doc; Microsoft.Office.Interop.Visio.Shape connector; public Form1() { InitializeComponent(); }

关于保存，有三种方式： //保存已存在文件
this.Application.ActiveDocument.Save();
//保存为新文件名
string docPath = System.Environment.GetFolderPath(System.Environment.SpecialFolder.MyDocuments) + @"\test\MyDrawing.vsd";
this.Application.ActiveDocument.SaveAs(docPath); //保存为新文件名并带参数
string newDocPath = System.Environment.GetFolderPath(System.Environment.SpecialFolder.MyDocuments) + @"\test\MyOtherDrawing.vsd";
this.Application.ActiveDocument.SaveAsEx(newDocPath,
((short)Microsoft.Office.Interop.Visio.VisOpenSaveArgs.visSaveAsRO +
(short)Microsoft.Office.Interop.Visio.VisOpenSaveArgs.visSaveAsListInMRU));
