我怎样才能改变webClient.UploadData的时间限制（）？

Question

我使用WebClient.UploadData()做一个Java服务器上的职位。如何延长时间限制？ （据我试图做一些调试，每次超时）

Answer 1

在Web客户端不具有超时属性，但它是可以从Web客户端继承给访问超时上所使用的内部的WebRequest：

 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，对于那些谁在VB代码...

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
