WebClient.DownloadFile - Invalid URI: The hostname could not be parsed

So I tried this in several different formats and produced different results. I will include all relevant information below.
My company uses a web-based application to schedule the generation of reports. The service emails a URL that can be clicked on and will immediately begin the "Open Save As Cancel" dialogue box. I am trying to automate the process of downloading these reports with a C# script as part of a Visual Studio project (the end goal is to import these reports in SQL Server).
I am encountering terrible difficulty initiating the download of this file using WebClient Here is the closest I have gotten with any of the methods I have tried:
*NOTE: I removed all identifying information from the URL, but left all special characters and the basic architecture intact. Hopefully this will be a happy medium between protecting confidential info and giving you enough to understand my dilemma. The URL does work when manually copied and pasted into the address bar of internet explorer.
Error Message:
"Invalid URI: The hostname could not be parsed."
public void Main()
{
using (var wc = new System.Net.WebClient())
{
wc.DownloadFile(
new Uri(#"http:\\webapp.locality.company.com\scripts\rds\cgigetf.exe?job_id=3058352&file_id=1&format=TAB\report.tab"),
#"\\server\directory\folder1\folder2\folder3\...\...\...\rawfile.tab");
}
}
Note also that I have tried to set:
string sourceUri = #"http:\\webapp.locality.company.com\scripts\rds\cgigetf.exe?job_id=3058352&file_id=1&format=TAB\report.tab\abc123_3058352.tab";
Uri uriPath;
Uri.TryCreate(sourceUri, UriKind.Absolute, out uriPath);
But uriPath remains null - TryCreate fails.
I have attempted doing a webrequest / webresponse / WebStream, but it still cannot find the host.
I have tried including the download URL (as in my first code example) and the download URL + the file name (as in my second code example). I do not need the file name in the URL to initiate the download if I do it manually. I have also tried replacing the "report.tab" portion of the URL with the file name, but to no avail.
Help is greatly appreciated as I have simply run out of thoughts on this one. The only idea I have left is that perhaps one of the special characters in my URL is getting in the way, but I don't know which one that would be or how to handle it properly.
Thanks in advance!

My first thought would be that your URI backslashes are being interpreted as escape characters, leading to a nonsense result after evaluation. I would try a quick test where each backslash is escaped as itself (i.e. "\" instead of "\" in each instance). I'm also a little puzzled as to why your URI is not using forward slashes...?
// Create an absolute Uri from a string.
Uri absoluteUri = new Uri("http://www.contoso.com/");

Selenium WebDriver file upload browse button c#

I have problem with browse button and switching to file dialog. I cannot use my file path control and just send there my string with file path and file itself, as it's readonly and in fact some behind control is my input filepath.
Here's my code
driver.FindElement(By.Id("browseButton")).Click();
driver.SwitchTo().ActiveElement().SendKeys(filepath);
Above code fills my control for file path, as i can see that on UI. But my open file dialog is still opened and i do not know how to close it and submit my upload.

Uploading files in Selenium can be a pain, to say the least. The real problem comes from the fact that it does not support dialog boxes such as file upload and download.
I go over this in an answer to another question, so I will just copy/paste my answer from there here. The code examples should actually be relevant in your case, since you are using C#:
Copied from previous answer on question here:
Selenium Webdriver doesn't really support this. Interacting with non-browser windows (such as native file upload dialogs and basic auth dialogs) has been a topic of much discussion on the WebDriver discussion board, but there has been little to no progress on the subject.
I have, in the past, been able to work around this by capturing the underlying request with a tool such as Fiddler2, and then just sending the request with the specified file attached as a byte blob.
If you need cookies from an authenticated session, WebDriver.magage().getCookies() should help you in that aspect.
edit: I have code for this somewhere that worked, I'll see if I can get ahold of something that you can use.
public RosterPage UploadRosterFile(String filePath){
Face().Log("Importing Roster...");
LoginRequest login = new LoginRequest();
login.username = Prefs.EmailLogin;
login.password = Prefs.PasswordLogin;
login.rememberMe = false;
login.forward = "";
login.schoolId = "";
//Set up request data
String url = "http://www.foo.bar.com" + "/ManageRoster/UploadRoster";
String javaScript = "return $('#seasons li.selected') .attr('data-season-id');";
String seasonId = (String)((IJavaScriptExecutor)Driver().GetBaseDriver()).ExecuteScript(javaScript);
javaScript = "return Foo.Bar.data.selectedTeamId;";
String teamId = (String)((IJavaScriptExecutor)Driver().GetBaseDriver()).ExecuteScript(javaScript);
//Send Request and parse the response into the new Driver URL
MultipartForm form = new MultipartForm(url);
form.SetField("teamId", teamId);
form.SetField("seasonId", seasonId);
form.SendFile(filePath,LoginRequest.sendLoginRequest(login));
String response = form.ResponseText.ToString();
String newURL = StaticBaseTestObjs.RemoveStringSubString("http://www.foo.bar.com" + response.Split('"')[1].Split('"')[0],"amp;");
Face().Log("Navigating to URL: "+ newURL);
Driver().GoTo(new Uri(newURL));
return this;
}
Where MultiPartForm is:
MultiPartForm
And LoginRequest/Response:
LoginRequest
LoginResponse
The code above is in C#, but there are equivalent base classes in Java that will do what you need them to do to mimic this functionality.
The most important part of all of that code is the MultiPartForm.SendFile method, which is where the magic happens.

One of the many ways to do that is to remove the disable attribute and then use typical selenium SendKeys() to accomplish that
public void test(string path)
{
By byId = By.Id("removeAttribute");
const string removeAttribute = #"document.getElementById('browseButton').removeAttribute('disabled');";
((IJavaScriptExecutor)Driver).ExecuteScript(removeAttribute);
driver.FindElement(byId).Clear();
driver.FindElement(byId).SendKeys(path);
}

You can use this Auto IT Script to Handle File Upload Option.
Auto IT Script for File Upload:
AutoItSetOption("WinTitleMatchMode","2") ; set the select mode to
Do
Sleep ("1000")
until WinExists("File Upload")
WinWait("File Upload")
WinActivate("File Upload")
ControlFocus("File Upload","","Edit1")
Sleep(2000)
ControlSetText("File Upload" , "", "Edit1", $CmdLineRaw)
Sleep(2000)
ControlClick("File Upload" , "","Button1");
Build and Compile the above code and place the EXE in a path and call it when u need it.
Call this Once you click in the Browse Button.
Process p = System.Diagnostics.Process.Start(txt_Browse.Text + "\\File Upload", DocFileName);
p.WaitForExit();

WP Parse Enclosure url

i recently made an app using windows app studio online, and suprisingly the app turn out alright it handles the rss feeds quite nicely. Ive made some changes to the app, as the feed contains a enclosure url which is a download link. i cant get it to detect the enclosure url. i think im just expressing it wrong.
i tried every online rss source viewer to see if it appeared any different in yahoo pipes it appears as item.enclosure.url, on code beauty it appears as http://bla.com"/> ive tried every combination i can think of
i also tried putting the feed through yahoo pipes to give me a new feed with the enclosure url in a new tag
< downloadlink >< /downloadlink> and used the code
rssItem.FeedUrl = item.GetSafeElementString("downloadlink")
and the whole app works as it should so i know the only thing im doing wrong is retieving the enclosure url the only problem with yahoo pipes is you cant change the input url which i need to do so it has to come from the enclosure url
so my question is how should i retrieve the tag
rssItem.FeedUrl = item.GetSafeElementString("whatgoeshere")
thanks

This Worked Nicely
XElement element = item.Element("enclosure"); //new element
int length = (int)element.Attribute("length"); //seprate attributes
string type = (string)element.Attribute("type");
string url = (string)element.Attribute("url");
rssItem.FeedUrl = url; // use the result

Moving XML file to be hosted

Please be gentle. I am not a terribly proficient developer!
So this is the last thing I need to fix in my Windows Phone 7.5 app before I consider it done. In short, the data sources on the menus are driven by an xml file. That file is stored locally with the app. I would like to store that file somewhere on the Internet). Currently if I need to make a change to this xml file, I have to re-submit the app to the Marketplace taking about 5 days before the change goes live. How 2003 of me.
So I can't figure out what they are expecting returned in the code below. I've hacked away and it always give some error I don't understand.
I've set the filename variable to a URL of a file on the Internet but apparently that is not supported. So I either need a new way for that whole section to work or a way to convert the hosted filename converted into something that will work.
private static void FirstLaunch()
{
// On the first launch, just add everything from the OPML file
string filename;
//This file should really be hosted on the Internet somewhere.
filename = "/RSSReader;component/LyncNews-opml.xml";
StreamResourceInfo xml = App.GetResourceStream(new Uri(filename, UriKind.Relative));
List<RSSPage> rssPages = ParseOPML(xml.Stream);
}

You can set it to a URL, but you'll need to download the content, not through App.GetResourceStream. Try WebClient, it's easy and simple.
A simple usage:
WebClient client = new WebClient();
client.DownloadStringCompleted += new DownloadStringCompletedEventHandler(Client_DownloadStringCompleted);
Uri token = new Uri("your url");
client.DownloadStringAsync(token);
and handle xml parsing in the event.

How does Response.Redirect calculate the URL for "~/folder1/folder2/some.aspx"

This might sound like a trivial problem but for some reason it is not.
Instead of needing to redirect
Response.Redirect("~/folder1/folder2/some.aspx")
I need the location as if it behaved like
string navigatingUrl = Response.Redirect("~/folder1/folder2/some.aspx")
Trying to replicate this I started with
string navigatingUrl = new Uri(HttpContext.Current.Request.Url,
new Uri("~/folder1/folder2/some.aspx", UriKind.Relative));
This instead generates "http://www.fullRequestUrl/~/folder1/folder2/some.aspx"
Edit: Well I've found out why I absolutely hate the URL API from Microsoft. I wish hellfire to whoever wrote this line of code
else if (uriKind == UriKind.Relative)
{
// Here we know that we can create an absolute Uri, but the user has requested
only a relative one
e = GetException(ParsingError.CannotCreateRelative);
}
What would possess someone to throw an error like that? This single if statement completely destroys the API.

I think you are looking for Control.ResolveUrl(). Typically you would probably use the method found on your Page object (if you are using WebForms).

Stealing from Get absolute url for a file in my asp.net project to include HTTP// etc for use externally? the only absolute way to do this is:
string url = Request.Url.GetLeftPart(UriPartial.Authority)
+ VirtualPathUtility.ToAbsolute(relativePath)

Response.Redirect(Page.ResolveUrl("~/folder1/forlder2/some.aspx"), false);
