How can I download video files programmatically in C# [modified]

[desamsetty]

Hi All, I have a web application and I would like to download video files i.e. .flv or .wmv files from a web site, for example, youtube or google programmatically in my c# code. If you know how to do this please respond to this message. I appreciate your help. Thanks. -- modified at 19:23 Thursday 14th September, 2006

Are you saying you want to offer video files to be viewed on your website, direct from your web servers hard drive? Or a way to retrieve video files from google video and YouTube to be used in your application some how?

Similar to something I posted a few messages up... you'll want to modify this to be a bit more asynchronous, especially if you're downloading large files like videos. This function downloads the contents of the web file and stores it in a temp file and returns the temp file name.

public string GetWebFile(string url)
{
HttpWebRequest webRequest = null;
HttpWebResponse webResponse = null;
Stream responseStream = null;
FileStream fileStream = null;
string filename = "";

try
{
    // Create the web request
    webRequest = (HttpWebRequest)HttpWebRequest.Create(url);
    // Get the response
    webResponse = (HttpWebResponse)webRequest.GetResponse();
    // Get the response stream
    responseStream = webResponse.GetResponseStream();
    // write it to a temporary file in 1000 byte chunks
    filename = Path.GetTempFileName();
    fileStream = new FileStream(filename, FileMode.Append);
    int bytesRead = 0;
    byte\[\] data = new byte\[1000\];
    // keep looping until we read nothing
    do
    {
        // read the next 1000 bytes of data
        bytesRead = responseStream.Read(data, 0, 1000);
        // write the data to the file
        fileStream.Write(data, 0, bytesRead);
    }
    while (bytesRead > 0);
}
catch (Exception e)
{
    MessageBox.Show("Error : " + e.Message);
}
finally
{
    // free any resources
    if (fileStream != null)
    {
        fileStream.Close();
        fileStream.Dispose();
    }
    if (responseStream != null)
    {
        responseStream.Close();
        responseStream.Dispose();
    }
    if (webResponse != null)
    {
        webResponse.Close();
    }
}

// return the contents
return filename;

}
