这里地址的方法也是可用的,但是net3.5不能使用 https://zhidao.baidu.com/question/754345532496123564.html
为此我选择使用win32api的方式来遍历当前桌面所有资源管理器
public static class Command_jjOpenFilePath { /// <summary> /// 不重复打开dwg路径的资源管理器 /// </summary> [CommandMethod("JJ_OpenDwgFilePath")] public static void JJ_OpenDwgFilePath() { Database db = HostApplicationServices.WorkingDatabase;//当前的数据库 Editor ed = Application.DocumentManager.MdiActiveDocument.Editor; ed.WriteMessage("\n****惊惊盒子-打开当前Dwg的目录"); try { var filename1 = Intranet.GetUNCPath(db.Filename); var filename2 = CadSystem.Getvar("dwgprefix") + CadSystem.Getvar("dwgname"); var regex = new Regex(".dwt");//正则 //符合.dwt默认面板 || 文件不存在(这个才支持局域网) if (regex.IsMatch(filename1) || !File.Exists(filename2)) { ed.WriteMessage("\n你没有保存文件!"); } else { ShellWindows wins = new ShellWindows();//这个名字是为了兼容高版本(没想到吧 foreach (InternetExplorer item in wins) { if (item.LocationURL + "\\" + CadSystem.Getvar("dwgname") == filename2) { item.Quit();//关闭 } } Process.Start("explorer", "/select," + filename2);//重开一个,防止选择状态被改变 } } catch (System.Exception e) { ed.WriteMessage(e.Message); throw e; } }
迭代器使用:
public struct InternetExplorer { public IntPtr HWND { get; set; }//句柄 public string LocationURL { get; set; }//文件夹路径 public void Quit()//关闭文件夹 { Win32api.QuitToolbar(HWND); } } /// <summary> /// 遍历桌面资源管理器 /// </summary> public class ShellWindows : IEnumerable { private readonly ArrayList list; public IEnumerator GetEnumerator() { return (list as IEnumerable).GetEnumerator(); } /// <summary> /// 获取桌面所有文件夹的路径 /// </summary> /// <returns></returns> public ShellWindows() { var allDesktopWindows = Win32api.GetAllDesktopWindows(); var lst = new List<InternetExplorer>(); foreach (var item in allDesktopWindows) { if (item.className == "CabinetWClass") { string a = item.windowName; var fi = Win32api.FindWindowEx(item.hwnd, 0, "WorkerW", null); if (fi != IntPtr.Zero) { fi = Win32api.FindWindowEx(fi, 0, "ReBarWindow32", null); if (fi != IntPtr.Zero) { fi = Win32api.FindWindowEx(fi, 0, "Address Band Root", null); if (fi != IntPtr.Zero) { fi = Win32api.FindWindowEx(fi, 0, "msctls_progress32", null); if (fi != IntPtr.Zero) { fi = Win32api.FindWindowEx(fi, 0, "Breadcrumb Parent", null); if (fi != IntPtr.Zero) { fi = Win32api.FindWindowEx(fi, 0, "ToolbarWindow32", null);//资源管理器 //知识:toolbar上的按钮没有handler,要用发送通知信息 if (fi != IntPtr.Zero) { StringBuilder sb = new StringBuilder(256); //获取窗口名称-路径地址 Win32api.GetWindowText(fi, sb, sb.Capacity); string path = sb.ToString(); path = path.Substring(4, path.Length - 4);//4表示"地址: "长度 InternetExplorer ie = new InternetExplorer { HWND = item.hwnd, LocationURL = path }; lst.Add(ie); } } } } } } } } list = new ArrayList(lst); } }
win32api使用:
