web URL scrapping ? ? ? advice also appreciated .

Have you added the reference for TextParser?

Ty for your references been helpful . ty ty very much

Here some code : throwing compile time error "TEXTPARSER " . reference not added like that ..can you please make this code wok . textparserin which namespace or which assembly i need to import .. TY

Hello Sunil,

Refer this one:

No one will give you the code in hand as it is big[time consuming] task. Try to search on each statements in google, will get the solutions for each one. Try it yourself & post if you have any questions.

Above is the nice example for WebAPI request batching. Almost you 60% of work is covered.
