如何使用vb.net从GitHub Enterprise下载all_user.csv报告并避免404错误？我可以使用Curl做到这一点

Question

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
