将Web服务的输出存储在虚拟目录中

Question

I have created a web service which gives the data in JSON format, I am going to read this data to create a high-charts. When I coded this web service , I get values in string which I have serialized into JSON format and store it my folder on system, but problem is when I will deploy my web service in remote machine that time I will face the problem to store the file since I have provided local path as explained in below code,

System.IO.File.WriteAllText(@"C:\Json\Json.json", jSearializer.Serialize(modified_listofstrings));

Can anyone please suggest what I am suppose to do so that I can store this file in such a way that it will be easy to access after deployment of my web service in remote machine?

Is that possible or I will have to create a simple asp.net application and consume that web service and store that file in the folder of that newly created application?

I am very new to this concept hence I don't know about storing in virtual folder or something like that, I got suggestion to do so, It will be very grateful if someone explains me the concept as well...

Answer 1

You have two ways:

1. Give write permission to your application identity to write in c:\\json folder, which is not a good idea.

2. Change your code to use relative path:

    File.WriteAllText(System.Web.HttpContext.Current.Server.MapPath("/json"), "json-text"); 

Server.MapPath maps a virtual directory to it's equivalent absolute directory in OS. For example, if your website is hosted in c:\\websites\\json-project\\ , then using Server.MapPath("/foo") would be translated to c:\\websites\\json-project\\foo path.

By default any ASP.NET application has full access to all of its folders.

Answer 2

You can find the physical path to your application by giving relative path something like Server.MapPath("/Json/Json.json")

Server.MapPath("."), Server.MapPath("~"), Server.MapPath(@"\\"), Server.MapPath("/"). What is the difference?
