How to save image from remote URL using C# asp.net?

Question

I am working on asp.net C# website in that I getting problem when I try to save image from remote URL.
I have tried with below c# code ...

// C# code

string remoteImageUrl= "http://www.bitpixels.com/getthumbnail?code=83306&url=http://live.indiatimes.com/default.cms?timesnow=1&size=200";
string strRealname = Path.GetFileName(remoteImageUrl);
string exts=Path.GetExtension(remoteImageUrl);

WebClient webClient = new WebClient();
webClient.DownloadFile(remoteImageUrl,Server.MapPath("~/upload/")+strRealname + exts);

When I fetch image from above remoteImageUrl then
I getting error "An exception occurred during a WebClient request."

How can I fetch and save remote url image and store it my website upload directory.
or any other way to get remote url image.

Your code works just fine for me. Are you getting any further information in the Exception? Any InnerException? — DavidGouge

I solved that problem The exception comes due to the extension..

When I getting extension of the remoteImageUrl Path.

string exts = Path.GetExtension(remoteImageUrl);
string strRealname = Path.GetFileName(remoteImageUrl);

It returns ".cms" so exception throws at that point, I avoid the ".cms" extension from the remoteImageURL and then call

WebClient webClient = new WebClient();
webClient.DownloadFile(remoteImageUrl,Server.MapPath("~/upload/")+strRealname + exts);

It works fine.

Yout code is just fine. Make sure your application pool identity, has access to "upload" folder with write access.

And if you are using a proxy server you should also specify this in web.config file.

<system.net>
  <defaultProxy enabled="true" useDefaultCredentials="true"></defaultProxy>
</system.net>

Are you running under anything less than full trust? If so, you can't make arbitrary web requests either.
