c# - 如何从服务器资源管理器检索 connectionStrings

Question

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

我使用以下代码将 MyCommand 项添加到服务器资源管理器中表的上下文菜单中:

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);
}

获取所选表格项的名称:

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);

如何获取有关数据库连接的信息？

                        if (connection != null && connection.ConnectionSupport.ProviderObject != null)
                        {
