Searched out on the internet and didn't really find anything that was horribly succinct, so I wrote this class for fun. I had help from http://www.codeproject.com/cs/webservices/translation.asp. I hope you enjoy! Here's the code to call it:
PostSubmitter post=new PostSubmitter();
post.Url="http://seeker.dice.com/jobsearch/servlet/JobSearch";
post.PostItems.Add("op","100");
post.PostItems.Add("rel_code","1102");
post.PostItems.Add("FREE_TEXT","c# jobs");
post.PostItems.Add("SEARCH","");
post.Type=PostSubmitter.PostTypeEnum.Post;string result=post.Post();
And here's the class:
using System;using System.Text;using System.IO;using System.Web;using System.Net;using System.Collections.Specialized;
