This code will help you to screen scrap or web scrap yahoo mail. Replace the uservame and password with your user name and password.
It is recomended that whenever you copy and paste some code from some sites you just go through that ,because there may be some tricks which will take your user name and password to the author. Here there is no such code. But still have a check and learn the code.
For web scraping replace the links to your page and handle it, there you will not have to login every time. Just diclare the "cookieContainer" as global and call the function GetPage for the pages you got after login If you have any doubt you are free to ask. If you need more explanation of the codes i will add that. So respond to the post if you need any help .Here is the code
protected void Page_Load(object sender, EventArgs e)
{
Response.Write(FormLoginGet("https://login.yahoo.com/config/login?",
