如何使用C#进行Visio二次开发

      Visio在VB6中的开发有很多现成的项目及代码，但在.NET领域相对比较滞后，但是从Visio SDK2007发布以来，给予Visio的C#开发逐渐多了起来，虽然和VB6的开发思路有一定的相似，不过平台不一样，做出来的东西差别还是有一定的距离，虽然总体慢一点，但是，DotNET框架的逐渐强大以及更多的DotNet程序和开发人员的加入，带给大家更高的整合价值以及更美好的发展未来。
    本人将会在C#领域将Visio的二次开发进行下去，希望大家一起学习研究，碰撞出更美的火花

Visio的几个重要对象

 Application
 Window （Application.ActiveWindow)
 Document （Application.ActiveDocument)
 Master、Shape

Visio XML格式文件分析
 Master格式

 
Pages/Shapes格式 

 图纸的XML文档中，Master后面的Shapes集合中只有一个Shape对象
 图纸的Shapes集合有多个对象，每个对象的NameU和Name值可能不一样，一般使用NameU


Visio基本操作的实现

VisApplication = this.ctrlDrawing.Document.Application;
VisWindow = VisApplication.ActiveWindow;
VisDocument = VisApplication.ActiveDocument;

//Settings
VisApplication.Settings.ShowShapeSearchPane = false; //显示搜索形状窗体
VisApplication.Settings.EnableAutoConnect = false; //自动链接（2007默认）
VisApplication.Settings.StencilBackgroundColor = 10070188; //vbGrayText

//文档各种显示
VisApplication.DoCmd((short)VisUICmds.visCmdViewRulers);
VisApplication.DoCmd((short)VisUICmds.visCmdViewGrid);
VisApplication.DoCmd((short)VisUICmds.ShowGuides);
VisApplication.DoCmd((short)VisUICmds.ShowConnectPoints);
VisApplication.DoCmd((short)VisUICmds.ShowPageBreaks);

//各种窗口
VisApplication.DoCmd((short)VisUICmds.visCmdShapesWindow);
VisApplication.DoCmd((short)VisUICmds.visCmdPanZoom);
VisApplication.DoCmd((short)VisUICmds.visCmdCustProp);
VisApplication.DoCmd((short)VisUICmds.visCmdSizePos);


SendKeys.Send("^(x)");
//VisApplication.DoCmd((short)VisUICmds.visCmdUFEditCut);
SendKeys.Send("{DELETE}");
//VisApplication.DoCmd((short)VisUICmds.visCmdUFEditClear);
SendKeys.Send("^+(p)");
//VisApplication.DoCmd(VisUICmds.visCmdFormatPainter);
SendKeys.Send("^(z)");
//VisApplication.DoCmd(VisUICmds.visCmdEditUndo);

调用工具条对象、菜单对象的方法
Application.CommandBars
Microsoft.Office.Core.CommandBars共享Office对象模型
使用CommandBar代替UIObject
CommandBar对象中，菜单及工具条是同一个东西
CommandBar、CommandBarButton、 CommandBarComboBox、CommandBarControl、 和 CommandBarPopup

示例：执行视图中的工具条的所有按钮事件。

Microsoft.Office.Core.CommandBars commandBars;
commandBars = (Microsoft.Office.Core.CommandBars)VisApplication.CommandBars;

foreach (Microsoft.Office.Core.CommandBarControl control in commandBars["View"].Controls)
{
    Microsoft.Office.Core.CommandBarButton button =  control as  Microsoft.Office.Core.CommandBarButton;
    if (button != null)
    {
        button.Execute();
    }
}

StringBuilder sb = new StringBuilder();
foreach (Microsoft.Office.Core.CommandBar bar in commandBars)
{
    sb.Append(string.Format("CommandBar Name:{0}\r\n", bar.Name));
    foreach(Microsoft.Office.Core.CommandBarControl control in bar.Controls)
    {
        Microsoft.Office.Core.CommandBarButton button =  control as  Microsoft.Office.Core.CommandBarButton;
        if(button != null)
        {
            sb.Append(string.Format("Button Name:{0} \r\n", button.Caption));
        }                    
    }
}
Form2 frm = new Form2();
frm.txtContent.Text = sb.ToString();
frm.Show();


short flags = (short)VisOpenSaveArgs.visOpenDocked | (short)VisOpenSaveArgs.visOpenRO;
StencilOpenEx(wndVisio.Application, flags);

/**//// <summary>
/// 打开模具的公共方法
/// </summary>
/// <param name="visApp">按引用调用的VisioApplication对象</param>
/// <param name="flags">打开的模式</param>
private void StencilOpenEx(Application visApp, short flags)
{
    List<string> stencilList = GetStencils();
    string stencilFileName;
    
    foreach(string stencil in stencilList)
    {
        stencilFileName = GetStencilsFileName(stencil);
        if(!string.IsNullOrEmpty(stencilFileName))
        {
            visApp.Documents.OpenEx(Portal.gc.gStencileFileBasePath + stencilFileName, flags);
        }
    }
}

//关闭模具文件
visApp.Documents["Switch.vss"].Close();
visApp.Documents["Span.vss"].Close();
visApp.Documents["Line.vss"].Close();
visApp.Documents["Label.vss"].Close();
visApp.Documents["Construct.vss"].Close();
visApp.Documents["Monitor.vss"].Close();

Visio Shape的属性操作
  StringToFormulaForString、FormulaStringToString函数
  访问属性
  设置属性
  添加属性

//列出模具组
this.cmbStencilGroup.Items.Clear();
List<string> stencilGroups = stencil.GetStencils();
foreach (string group in stencilGroups)
{
    this.cmbStencilGroup.Items.Add(group);
}


//根据模具组列出模具
string stencilName = stencil.GetStencilsFileName(this.cmbStencilGroup.Text);
this.cmbStencil.Items.Clear();
string tempName;
foreach (Master master in visApp.Documents[stencilName].Masters)
{
    tempName = master.Name;
    if (!stencil.IsExcludeItem(tempName))
    {
        this.cmbStencil.Items.Add(tempName);
    }
}


//根据模具，获取对应的属性集合，遍历属性集合，列出属性名称
