如何从服务器资源管理器检索连接字符串

Question

我想写一个扩展到Visual Studio，这将使我能够为指定的表生成一个模型。

我用下面的代码mycommand的项目加入到表的上下文菜单中的服务器资源管理器：

Commands2 commands = (Commands2)_applicationObject.Commands; 
CommandBar menuBarCommandBar = ((CommandBars)_applicationObject.CommandBars)["Object Node"]; 

Command command = commands.AddNamedCommand2(_addInInstance, "MyCommand", "MyCommand", 
    "Executes the command for MyCommand", true, 59, ref contextGUIDS, 
    (int)vsCommandStatus.vsCommandStatusSupported + (int)vsCommandStatus.vsCommandStatusEnabled, 
    (int)vsCommandStyle.vsCommandStylePictAndText, vsCommandControlType.vsCommandControlTypeButton); 
if ((command != null) && (menuBarCommandBar != null)) 
{ 
     command.AddControl(menuBarCommandBar, 1); 
} 

获取所选表项目的名称：

string fileName = "Dafault.cs"; 
var serverExplorer = _applicationObject.ToolWindows.GetToolWindow("Server Explorer") as UIHierarchy; 
if (serverExplorer != null) 
{ 
    dynamic item = ((object[])serverExplorer.SelectedItems)[0]; 
    fileName = string.Format("{0}.cs", item.Name); 
} 

//... 
// Generate model based on table from database 
//... 

_applicationObject.ItemOperations.NewFile("General\\Text File", fileName, Constants.vsViewKindCode); 

我怎样才能获取有关数据库连接的信息？

找到解决方案。 使用this

 
public static IDbConnection GetConnection(DSRefNavigator navigator, out string type) 
     { 
      type = null; 
      try 
      { 
       if (navigator != null) 
       { 
        IVsDataConnectionsService dataConnectionsService = 
         (IVsDataConnectionsService) Package.GetGlobalService(typeof(IVsDataConnectionsService)); 
        string itemName = navigator.GetConnectionName();
 

   if (itemName != null) 
       { 
        int iConn; // = dataConnectionsService.GetConnectionIndex(itemName); 
        DataViewHierarchyAccessor dataViewHierarchy = null; 

        for(iConn = 0; iConn < dataConnectionsService.Count; iConn++) 
        { 
         DataViewHierarchyAccessor hierarchyAccessor = 
          new DataViewHierarchyAccessor((IVsUIHierarchy) dataConnectionsService.GetConnectionHierarchy(iConn)); 
         try 
         { 
          if (hierarchyAccessor.Connection.DisplayConnectionString == itemName) 
          { 
           dataViewHierarchy = hierarchyAccessor; 
           break; 
          } 
         } 
         catch 
         { 
         } 
        } 
        if (dataViewHierarchy != null) 
        { 
         DataConnection connection = dataViewHierarchy.Connection; 
         if (connection != null && connection.ConnectionSupport.ProviderObject != null) 
         { 
          type = connection.ConnectionSupport.ProviderObject.GetType().FullName; 
          return (IDbConnection) connection.ConnectionSupport.ProviderObject; 
         } 
        } 
       } 
      } 
     } 
     catch 
     { 
     } 

     return null; 
    }
