这里地址的方法也是可用的,但是net3.5不能使用
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
/// <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
{
string dwgname = CadSystem.Getvar("dwgname"); var filename1 = Intranet.GetUNCPath(db.Filename);
var filename2 = CadSystem.Getvar("dwgprefix") + 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 + "\\" + 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, , "WorkerW", null);
if (fi != IntPtr.Zero)
{
fi = Win32api.FindWindowEx(fi, , "ReBarWindow32", null);
if (fi != IntPtr.Zero)
{
fi = Win32api.FindWindowEx(fi, , "Address Band Root", null);
if (fi != IntPtr.Zero)
{
fi = Win32api.FindWindowEx(fi, , "msctls_progress32", null);
if (fi != IntPtr.Zero)
{
fi = Win32api.FindWindowEx(fi, , "Breadcrumb Parent", null);
if (fi != IntPtr.Zero)
{
fi = Win32api.FindWindowEx(fi, , "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();
//获取窗口名称-路径地址
Win32api.GetWindowText(fi, sb, sb.Capacity);
string path = sb.ToString();
path = path.Substring(, path.Length - );//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:

这里有讨论如何通过shell32设置选择文件夹,但是我的程序是关掉所有相同的,再打开一个新的.就没有实现了
