We can read RSS feeds using ASP.NET with C# code. In the below example, if you click on button all rss feed data will read and display on the webpage. In the corporate network we are unable to read RSS feeds with out using proxy. Please give your proxy name in the below line. Basically, this proxy programming required in the corporate networks. That's it entire code will work.
Output page:
.aspx Code
C# Code behind.
WebProxy proxyObject = new WebProxy("http://proxyName:8080/", true);
Output page:
