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));

   /// 
    /// 获取应用程序web.config中的文件配置路径,并返回物理路径
    /// 适用于web应用程序
    /// 
    /// 
    /// 
    public static string GetFileFullpath(string key)
    {
        if (string.IsNullOrEmpty(key)) return string.Empty;


        //获取应用程序的web.config中配置的路径
        string appSetting = System.Configuration.ConfigurationManager.AppSettings[key].ToString();
        //如果到的路径不是物理路径,则映射为物理路径
        if (!Path.IsPathRooted(appSetting)) appSetting = System.Web.HttpContext.Current.Server.MapPath(appSetting);


        return appSetting;
    }



    /// 
    /// 获取应用程序.config中的文件配置路径,并返回物理路径
    /// 适用于windows服务、控制台等应用程序
    /// 
    /// 
    /// 
    public static string GetAssemblyPath(string key)
    {
        if (string.IsNullOrEmpty(key)) return string.Empty;


        //获取应用程序的web.config中配置的路径
        string appSetting = System.Configuration.ConfigurationManager.AppSettings[key].ToString();
        //如果到的路径不是物理路径,则映射为物理路径
        if (!Path.IsPathRooted(appSetting))
        {
            string assemblyPath = System.Reflection.Assembly.GetExecutingAssembly().Location;
            string dirName = Path.GetDirectoryName(assemblyPath);
            if (dirName.IndexOf(@"\bin\Debug") > -1)
                appSetting = dirName.Replace(@"\bin\Debug", appSetting.Substring(1).Replace(@"/", @"\"));
            else
                appSetting = dirName + appSetting.Substring(1).Replace(@"/", @"\");
        }


        return appSetting;
    }



    /// 
    /// 获取应用程序.config中的文件配置路径,并返回物理路径
    /// 适用于windows服务应用程序的成功安装之后
    /// 
    /// 
    /// 
    public static string GetInstallPath(string key)
    {
        if (string.IsNullOrEmpty(key)) return string.Empty;

        //获取应用程序的web.config中配置的路径
        string appSetting = System.Configuration.ConfigurationManager.AppSettings[key].ToString();
        //如果到的路径不是物理路径,则映射为物理路径
        if (!Path.IsPathRooted(appSetting))
        {
            string processPath = System.Diagnostics.Process.GetCurrentProcess().MainModule.FileName;
            appSetting = processPath.Substring(0, processPath.LastIndexOf(@"\")) + appSetting.Substring(1).Replace(@"/", @"\");
        }


        return appSetting;
    }
