如何获取记事本文件保存位置

Question

如果记事本文件保存在驱动器中，如何检索它的实际路径。例如，一个记事本进程是运行，它保存在驱动器的某个地方。我怎样才能检索它的完整路径？使用下面的代码我可以获得过程细节，但不是特定文件的实际路径。

Process[] localByName = Process.GetProcessesByName("notepad");
foreach (Process p in localByName)
    {
      string path  =  p.MainModule.FileName.ToString();
    }

此 returns 可执行路径，但我需要实际文件所在的驱动器位置。

Answer 1

Notepad++ 的 %APPDATA% 文件夹中有一个 session.xml 文件 here。

您可以使用 XDocument 或 XPath 来解析此文件并检索文件路径。以下是使用 XPath 获取它们的方法：

XmlDocument doc = new XmlDocument();
doc.Load(@"C:\Users\USERNAME_HERE\AppData\Roaming\Notepad++\session.xml");

XmlNodeList files = doc.SelectNodes("//NotepadPlus/Session/mainView/File");
foreach (XmlNode file in files)
{
  Console.WriteLine(file.Attributes["filename"].Value);
}

请注意，notepad++ 需要先关闭，然后 re-opened 才能刷新此文件。

Answer 2

应该这样做：

        string wmiQuery = string.Format("select CommandLine from Win32_Process where Name='{0}'", "notepad.exe");
        ManagementObjectSearcher searcher = new ManagementObjectSearcher(wmiQuery);
        ManagementObjectCollection retObjectCollection = searcher.Get();
        foreach (ManagementObject retObject in retObjectCollection)
        {
            string CommandLine = retObject["CommandLine"].ToString();
            string path = CommandLine.Substring(CommandLine.IndexOf(" ") + 1, CommandLine.Length - CommandLine.IndexOf(" ") - 1);
        }

只有通过双击或命令行打开文件才有效。

不要忘记添加对 System.Management 的引用，方法是右键单击项目，添加引用，然后 select 程序集选项卡并搜索 System.Management。

is definitely the best if you didn't open the file via File-> Open in notepad. For fun, I tried to create a solution that will work in all cases. You can achieve this with a combination of Microsoft TestApi 和 UIAutomation。基本上，我打开“另存为...”对话框以获取当前打开文件的文件路径。这很丑陋，但它有效！注意：安装 Microsoft.TestApi nuget 包，并添加对 WindowsBase、System.Drawing、UIAutomationClient 和 UIAutomationTypes 的引用。

namespace ConsoleApplication1
{
    class Program
    {
        [DllImport("user32.dll")]
        static extern bool SetForegroundWindow(IntPtr hWnd);

        static void Main(string[] args)
        {
        Process[] localByName = Process.GetProcessesByName("notepad");
        foreach (Process p in localByName)
        {
            string fileName = p.MainWindowTitle; // get file name from notepad title
            SetForegroundWindow(p.MainWindowHandle);
            AutomationElement windowAutomationElement = AutomationElement.FromHandle(p.MainWindowHandle);

            var menuElements = windowAutomationElement.FindAll(TreeScope.Descendants, new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.MenuItem));
            AutomationElement fileMenuElement = null;
            foreach (AutomationElement element in menuElements)
            {
                if (element.Current.Name == "File")
                {
                    fileMenuElement = element;
                    break;
                }
            }

            if (fileMenuElement != null)
            {
                fileMenuElement.SetFocus();
                fileMenuElement.Click();
                Thread.Sleep(800); // Sleeping an arbitrary amount here since we must wait for the file menu to appear before the next line can find the menuItems. A better way to handle it is probably to run the FindAll in the next line in a loop that breaks when menuElements is no longer null.
                menuElements = fileMenuElement.FindAll(TreeScope.Descendants, new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.MenuItem));
                var saveAsMenuElement = fileMenuElement.FindFirst(TreeScope.Descendants, new PropertyCondition(AutomationElement.NameProperty, "Save As..."));


                if (saveAsMenuElement != null)
                {
                    saveAsMenuElement.SetFocus();
                    saveAsMenuElement.Click();
                    Thread.Sleep(800);
                    var saveAsWindow = windowAutomationElement.FindFirst(TreeScope.Descendants, new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.Window));
                    var toolbarElements = saveAsWindow.FindAll(TreeScope.Descendants, new PropertyCondition(AutomationElement.ControlTypeProperty, ControlType.ToolBar));

                    foreach (AutomationElement element in toolbarElements)
                        if (element.Current.Name.StartsWith("Address:"))
                            Console.WriteLine(element.Current.Name + @"\" + fileName); // Parse out the file name from this concatenation here!
                    var closeButtonElement = saveAsWindow.FindFirst(TreeScope.Descendants, new PropertyCondition(AutomationElement.NameProperty, "Close"));
                    closeButtonElement.Click();
                }
            }
        }

        Console.ReadLine();
    }
}

public static class AutomationElementExtensions

        Point somePoint;
        if (automationElement.TryGetClickablePoint(out somePoint))

    }
