C# WebClient Upload file to web

Question

Hi,

I would like to know if I code it correctly. To upload file manually to my workplace server, I have to use Login ID and Password. With the clode below, should I include my loginID and Password as well?

    public void SaveLogsToWeb(string logFileName)
    {
        WebClient webClient = new WebClient();
        string webAddress = null;
        try
        {
            webAddress = @"http://myCompany/ShareDoc/";

            webClient.Credentials = CredentialCache.DefaultCredentials;

            WebRequest serverRequest = WebRequest.Create(webAddress);
            WebResponse serverResponse;
            serverResponse = serverRequest.GetResponse();
            serverResponse.Close();

            webClient.UploadFile(webAddress + logFileName, "PUT", logFileName);
            webClient.Dispose();
            webClient = null;
        }
        catch (Exception error)
        {
            MessageBox.Show(error.Message);
        }
    }

When I run it, exception throws "(401) Unauthorized"

thanks.

Answer 1

You should never include user/password information in a code file. The reason this is throwing up a 401 is because the internet user and the application pool it's running under don't have write permissions to the directory you're attempting to write to.

Right-click on the directory and add /ASPNET and /Network Service as users with write permission. This should clear up the problem. Make sure you isolate the directory.

Here's a good msdn article on it: http://support.microsoft.com/kb/815153

When I include this code line serverRequest.Credentials = CredentialCache.DefaultCredentials; Now it complains error (403) Forbidden.

public void SaveLogsToWeb(string logFileName) 
{ 
    WebClient webClient = new WebClient(); 
    string webAddress = null; 
    try 
    { 
        webAddress = @"http://myCompany/ShareDoc/"; 

        webClient.Credentials = CredentialCache.DefaultCredentials; 

        WebRequest serverRequest = WebRequest.Create(webAddress); 
        serverRequest.Credentials = CredentialCache.DefaultCredentials;
        WebResponse serverResponse; 
        serverResponse = serverRequest.GetResponse(); 
        serverResponse.Close(); 

        webClient.UploadFile(webAddress + logFileName, "PUT", logFileName); 
        webClient.Dispose(); 
        webClient = null; 
    } 
    catch (Exception error) 
    { 
        MessageBox.Show(error.Message); 
    } 
}
