Come posso cambiare il limite di tempo per webClient.UploadData ()?

Question

Sto usando WebClient.UploadData() di fare un post su un server Java. Come posso prolungare il limite di tempo? (Cronometra fuori ogni volta che sto cercando di fare un po 'di debug)

Answer 1

Il WebClient non dispone di una proprietà di timeout, tuttavia è possibile ereditare dalla WebClient per dare accesso al timeout sul WebRequest interno utilizzato:

 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;
     }
 }

Utilizzo:

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

Quindi, per coloro che il codice in VB ...

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
