c#.net各种应用程序中获取文件路径的方法

控制台应用程序：Environment.CurrentDirectory、Directory.GetCurrentDirectory()

windows服务：Environment.CurrentDirectory

windows服务安装成功后：

1. System.Diagnostics.Process.GetCurrentProcess().MainModule.FileName

2. ///

/// 获取服务应用程序的安装路径(或者当前安装目录)///
/// /// public static string GetWindowsServiceInstallPath(string ServiceName)

{

string key = @”SYSTEM\CurrentControlSet\Services\” + ServiceName;

string path = Registry.LocalMachine.OpenSubKey(key).GetValue(“ImagePath”).ToString();

//替换掉双引号

path = path.Replace(“\”“, string.Empty);

FileInfo fi = new FileInfo(path);

return fi.FullName;

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

}

//windows 服务中使用log4net

string assemblyFilePath = Assembly.GetExecutingAssembly().Location;

string assemblyDirPath = Path.GetDirectoryName(assemblyFilePath);

string configFilePath = assemblyDirPath + “//log4net.config”;

DOMConfigurator.ConfigureAndWatch(new FileInfo(configFilePath));

        //如果到的路径不是物理路径，则映射为物理路径
