I'm trying to filter submitted web sites by attempting to browse them while bouncing the request off of OpenDNS. If the page received is the OpenDNS page, I'll assume the page shoudld be blocked.
How might I accomplish this task using the System.Net.WebClient class?
My program takes user input, replaces all spaces with "+", then inserts it into a search url for a specified web host. For example, the user enters:"How long is a foot?"
The generated URL (in this case I'm using dogpile.com) is:
"http://www.dogpile.com/info.dogpl/search/web?&q=How+long+is+a+foot"
This method has worked before for me, but now I just get an Internal Server Error every time the code is executed.

I seem to remember reading the MSDN somewhere that there was another method to download files from URIs other than using the webclient object. I'm trying to download some raw php files but every time I use the webclient object the server interprets them as an HTTP request and instead serves the default web page that the php file builds and not the php code itself.
View 3 RepliesI'm downloading a file from my website using WebClient.DownloadFile(),I'm wanting to do it asynchronously, so my UI stays responsive, that would require me creating an array of web clients, is that bad practice? Or is it acceptable?I have looked into FileWebRequest, but thought WebClient looked easier to implement.

I am using the web client to download a file. Which works ok. However, now I have to download many and the number of files to download will change everyday. I am not sure how I can get the web client to know which files have been downloaded or not? I was thinking of using a for loop to download each file. But I will never know how many there are to download? The web client could download the same file twice?

The above code will open a webclient, set the credentials (possible error?), create a stream of the entire page, and then load it into a string (str).I then scan through and look for what is needed (Gamerscore, Motto, Bio, etc)-in this case.This doesn't work however, it doesn't sign in.

View 9 RepliesIs it possible to send HTTP POST with some form data with System.Net.WebClient?If not, is there another library like WebClient that can do HTTP POST? I know I can use System.Net.HttpWebRequest, but I'm looking for something that is not as verbose.

This was done easily enough with the WebBrowser control, but I can't find any examples using System.Net.WebClient().

View 2 RepliesI can download the files I want. However, the client has insisted on creating different folders which will contain the version number. So the name of the folders would be something like this: 1.0.1, 1.0.2, 1.0.3, etc.So the files will be contained in the latest version in this case folder 1.0.3.

I need to parse a Unix text file so, I am using System.Net.WebClient to ftp into a Unix server then using the .DownloadFile() method to get the text file, but its coming in with the Unix end line ""; so is there a way to convert that to windows format while doing the DownloadFile method? I do re-read it after and fix it, I am just looking for a better way.
Or is there an alternate such as instead of a DownloadFile, and the two other steps above can I just read it into an array right off the Unix server?? If so then what method would I use?
