如何更改webClient.UploadData（）的时间限制？

我正在使用WebClient.UploadData()在Java服务器上发布post。 我该如何延长时限？ （每次我尝试进行一些调试时都会超时）

Answer 1

WebClient没有超时属性，但是可以从WebClientinheritance以在所使用的内部WebRequest上访问Timeout：

  public class WebClientEx : WebClient { public int Timeout {get; set;} protected override WebRequest GetWebRequest(Uri address) { var request = base.GetWebRequest(address); request.Timeout = Timeout; return request; } } 

用法：

  var myClient = new WebClientEx(); myClient.Timeout = 900000 // Daft timeout period myClient.UploadData(myUri, myData); 

Answer 2

所以对于那些用VB编码的人……

 Public Class WebClientExtended Inherits WebClient Public Property Timeout() As Integer Get Return m_Timeout End Get Set(value As Integer) m_Timeout = value End Set End Property Private m_Timeout As Integer Protected Overrides Function GetWebRequest(address As Uri) As WebRequest Dim request = MyBase.GetWebRequest(address) request.Timeout = Timeout Return request End Function End Class Function UploadFile(ByVal URL As String, ByVal FilePath As String, ByVal FileName As String) 'Call API to Upload File Dim myWebClient As New WebClientExtended myWebClient.Timeout = 10 * 60 * 1000 Dim responseArray As Byte() Dim responseString As String = "" Try responseArray = myWebClient.UploadFile(URL, FilePath + "/" + FileName) responseString = System.Text.Encoding.ASCII.GetString(responseArray) Catch ex As Exception responseString = "Error: " + ex.Message End Try Return responseString End Function
