?web、控制臺(tái)應(yīng)用程序、Windows服務(wù)中獲取文件路徑的方法

控制臺(tái)應(yīng)用程序：Environment.CurrentDirectory、Directory.GetCurrentDirectory()
windows服務(wù)：Environment.CurrentDirectory
windows服務(wù)安裝成功后：

1. System.Diagnostics.Process.GetCurrentProcess().MainModule.FileName
2. ///
   /// 獲取服務(wù)應(yīng)用程序的安裝路徑(或者當(dāng)前安裝目錄)///

/// /// public static string GetWindowsServiceInstallPath(string ServiceName)

//替換掉雙引號(hào)

path = path.Replace("\"", string.Empty);

FileInfo fi = new FileInfo(path);

//return fi.FullName.Directory.ToString();

}

//windows 服務(wù)中使用log4net
string assemblyFilePath = Assembly.GetExecutingAssembly().Location;
string assemblyDirPath = Path.GetDirectoryName(assemblyFilePath);
string configFilePath = assemblyDirPath + "//log4net.config";
DOMConfigurator.ConfigureAndWatch(new FileInfo(configFilePath));
