C# 如何使应用程序名称显示在“打开方式”列表中?
这是我问题的继续。我正在为*.bmp类型创建一个“打开方式”列表。根据该问题的答案,我已从注册表项创建了“打开方式”列表中的应用程序列表C# 如何使应用程序名称显示在“打开方式”列表中?,c#,wpf,registry,open-with,C#,Wpf,Registry,Open With,这是我问题的继续。我正在为*.bmp类型创建一个“打开方式”列表。根据该问题的答案,我已从注册表项创建了“打开方式”列表中的应用程序列表 public void RecommendedPrograms(string ext) { string baseKey = @"Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\." + ext; using (RegistryKey r
public void RecommendedPrograms(string ext)

using (RegistryKey rk = Registry.CurrentUser.OpenSubKey(baseKey + @"\OpenWithList"))
{
if (rk != null)
{
string mruList = (string)rk.GetValue("MRUList");
if (mruList != null)
{
foreach (char c in mruList.ToString())
{
string str=rk.GetValue(c.ToString()).ToString();
if (!progs.Contains(str))
{
progs.Add(str);
}
}
}

using (RegistryKey rk = Registry.CurrentUser.OpenSubKey(baseKey + @"\OpenWithProgids"))

foreach (string item in rk.GetValueNames())
progs.Add(item);

}
using (RegistryKey rk = Registry.ClassesRoot.OpenSubKey("." + ext + @"\OpenWithList"))
{
if (rk != null)
{
foreach (var item in rk.GetSubKeyNames())
{
if (!progs.Contains(item))

foreach (string item in rk.GetValueNames())
{
if (!progs.Contains(item))
{
progs.Add(item);
}
}
}
}
}
此方法将返回一个应用程序名称列表,如
- 画画
- ehshell.exe
- MSPaint.exe
- ois.exe
- VisualStudio.bmp.10.0
- QuickTime.bmp
public string GetRegisteredApplication(string StrProgID)
{
//
// Return registered application by file's extension
//
RegistryKey oHKCR;
RegistryKey oOpenCmd;
string command;
if (Environment.Is64BitOperatingSystem == true)
{
oHKCR = RegistryKey.OpenBaseKey(Microsoft.Win32.RegistryHive.ClassesRoot, RegistryView.Registry64);
}
else
{
oHKCR = RegistryKey.OpenBaseKey(Microsoft.Win32.RegistryHive.ClassesRoot, RegistryView.Registry32);
}
try
{
oOpenCmd = oHKCR.OpenSubKey(StrProgID + "\\shell\\open\\command");
if (oOpenCmd == null)
{
oOpenCmd = oHKCR.OpenSubKey("\\Applications\\" + StrProgID + "\\shell\\open\\command");
}
if (oOpenCmd != null)
{
command = oOpenCmd.GetValue(null).ToString();
oOpenCmd.Close();
}
else
{
return null;
}
}
catch (Exception ex)
{
return null;
}
return command;
}
现在,如何获取必须显示在菜单中的应用程序名称?
每次开始使用新应用程序时,Windows操作系统都会自动从exe文件的版本资源中提取应用程序名称,并将其存储在名为“MuiCache”的注册表项中,以备以后使用。MUICache数据存储在HKEY\U CURRENT\U USER\Software\Classes\Local Settings\Software\Microsoft\Windows\Shell\MUICache下
但是我们不能保证应用程序至少运行过一次。我们也可以直接从文件的版本资源中获取描述密钥,但是我在从命令(如)中分离应用程序路径时遇到了一些问题
%SystemRoot%\System32\rundll32.exe“%ProgramFiles%\Windows照片
查看器\PhotoViewer.dll“,ImageView\u全屏%1
我怎样才能得到姓名信息
下面是我的命令列表
- “C:\Windows\System32\rundll32.exe\”C:\Program Files\Windows 照片查看器\PhotoViewer.dll\,图像视图\u全屏%1
- “\”C:\Windows\eHome\ehshell.exe\”\%1“
- “C:\PROGRA~1\MIF5BA~1\Office14\OIS.EXE/shellOpen\%1”
- “\”C:\Program Files(x86)\Microsoft Visual Studio 10.0\Common7\IDE\devenv.exe\“/dde”
- “C:\Program Files(x86)\QuickTime\PictureViewer.exe\%1”
FileVersionInfo.GetVersionInfo(Path.Combine(Environment.SystemDirectory, "Notepad.exe"));
FileVersionInfo myFileVersionInfo = FileVersionInfo.GetVersionInfo(Environment.SystemDirectory + "\\Notepad.exe");
// Print the file name and version number.
Console.WriteLine("File: " + myFileVersionInfo.FileDescription + '\n' +
"Version number: " + myFileVersionInfo.FileVersion);
基于Amal的解决方案,您只需要处理两种情况: 1) 启动“C:\Windows\System32\rundll32.exe”的 2) 其他一切 如果您想要一些粗略的内容,可以将“C:\Windows\System32\rundll32.exe”替换为空字符串。将“s”替换为空字符串,将字符串a终止为第一个正斜杠(/)或%,然后修剪结果 您只需要输入所需名称的.dll或.exe名称(使用正则表达式可能会更优雅一些,如果需要处理更多场景,此解决方案将很快变得复杂)
然后通过Amal的一段代码运行它,你应该得到你想要的。更新:对不起,我误读了你的帖子 只有在基于扩展名而不是基于progID查找默认应用程序名时,这才有帮助

uint cOut = 0;
if (AssocQueryString(AssocF.Verify, AssocStr.FriendlyAppName, fileExtensionIncludingDot, null, null, ref cOut) != 1)
return null;
StringBuilder pOut = new StringBuilder((int)cOut);
if (AssocQueryString(AssocF.Verify, AssocStr.FriendlyAppName, fileExtensionIncludingDot, null, pOut, ref cOut) != 0)
return null;
return pOut.ToString();
}
}
你可以这样使用它
string applicationName = FileAssoc.GetApplicationName(".docx");
// results in "Microsoft Office Word"
我的代码,包括检查,以防止一些常见错误…希望它有帮助:-)
