Hi,

I created windows service in same solution.

In one project I included the files in App_Data folders.

I want to get the files in service.

How can we get files in windows service from web project in same solution.

Please suggest me

What I have tried:

This is my service code

public void GetDashboards()
        {
            string sPath = HttpContext.Current.Server.MapPath(string.Format(@"~/App_Data/Dashboards"));
            string[] lstFiles = Directory.GetFiles(sPath, "*.xml");
//This folder is existing in different project in same solution.Here I got object reference not set to an instance error.

            foreach (string item in lstFiles)
            {
                FileInfo objFileInfo = new FileInfo(item);
                string sFileName = objFileInfo.Name.Replace(objFileInfo.Extension, "");
                UpdateExtract(sFileName);
            }
        }

推荐答案

您的服务无法访问HttpContext，因为它未运行因为一个Web请求，它对网站的配置一无所知，例如它在光盘上的位置。您只需要通过使用配置文件（app.config）告诉服务路径，并将路径硬编码到配置文件中并使用ConfigurationManager读取该配置值。

Your service can't access HttpContext because it is not running as the result of a web request, and it knows nothing about the web site's configuration such as where it is located on the disc. You're just going to have to tell the service the path by using a config file (app.config) and hard-coding the path into the config file and reading that config value using ConfigurationManager.
