我正在尝试使用.net Framework 4.5.2通过vb.net下载GitHub Enterprise的all_users.csv文件，并收到以下错误消息： 远程服务器返回错误：（404）找不到。
我的代码是：
Module Module1
Sub Main()
Dim remoteUri As String = "https://ghe.webserver/stafftools/reports/all_users.csv"
Dim fileName As String = "all_users.csv"
Dim password As String = "PERSONALACCESSTOKEN"
Dim username As String = "USERNAME"
System.Net.ServicePointManager.Expect100Continue = True
System.Net.ServicePointManager.SecurityProtocol = System.Net.SecurityProtocolType.Tls12
Dim client As New System.Net.WebClient
client.Credentials = New System.Net.NetworkCredential(username, password)
client.DownloadFile(remoteUri, fileName)
End Sub
End Module
错误发生在第client.DownloadFile(remoteUri, fileName)行，完全例外
System.Net.WebException was unhandled
HResult=-2146233079
Message=The remote server returned an error: (404) Not Found.

但是，以下Curl命令有效（如此处所述：https://help.github.com/en/enterprise/2.17/admin/installation/site-admin-dashboard#reports）：
curl -L -u USERNAME:PERSONALACCESSTOKEN --insecure https://ghe.webserver/stafftools/reports/all_users.csv
