Download Shared APIs are not working.

Hello Guys,
Using below snippet, we are trying to download files. But it was not workings. Throwing errors like path not found....

try
{
using (var httpClient = new HttpClient())
{
using (var request = new HttpRequestMessage(new HttpMethod("GET"), "https://files.ltssmaryland.org/shares/XXXXX/folders/root/files/bundle-zip/download"))
{
var base64authorization = Convert.ToBase64String(Encoding.ASCII.GetBytes("XWXWXWXWXWXWXWWXW:x"));
request.Headers.TryAddWithoutValidation("Authorization", $"Basic {base64authorization}");
var response = httpClient.SendAsync(request);
response.Wait();
var result = response.Result;
byte[] mybytearray = null;
if (result.IsSuccessStatusCode)
{
mybytearray = result.Content.ReadAsByteArrayAsync().Result;
var stream = result.Content.ReadAsStreamAsync().Result;
File.WriteAllBytes("I:\\work\test.ZIP", mybytearray);
}
}
}
}
catch (Exception e) { }
}


Please do share few samples on c#.

Thank you
San
