如何更改webClient.UploadData（）的时间限制？

Question

我正在使用WebClient.UploadData()在Java服务器上发布帖子。我怎样才能延长时间限制？ （它每次我尝试做一些调试时超时）

Answer 1

WebClient没有超时属性，但它可以从WebClient继承，以允许访问所使用的内部WebRequest上的超时：

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);

因此，对于那些在VB代码谁...

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 

功能UploadFile（BYVAL URL作为字符串，BYVAL文件路径作为字符串，BYVAL文件名作为字符串）

'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
