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));
