Assembly:  System.Web.Services (in System.Web.Services.dll)

Public Overrides ReadOnly Property OneWay As Boolean

Property Value

Type: System.Boolean

true if the client does not wait for the server to completely process a method.

A SoapDocumentMethodAttribute or SoapRpcMethodAttribute applied to an XML Web service method or XML Web service client can specify whether the XML Web service method is one way by setting the OneWay property of the attribute.

The OneWay property can be accessed during any SoapMessageStage.

The following code fragment is part of a SOAP extension that logs the SOAP messages sent and received by an XML Web service client. This particular fragment outputs to that log file a phrase stating the XML Web service method is one-way, when the OneWay property is true.

 newStream.Position = 0
 Dim myFileStream As New FileStream(filename, FileMode.Append, _
    FileAccess.Write)
 Dim myStreamWriter As New StreamWriter(myFileStream)
 myStreamWriter.WriteLine( _
    "================================== Request at " & DateTime.Now)

 ' Print to the log file the request header field for SoapAction header.
 myStreamWriter.WriteLine("The SoapAction Http request header field is: ")
 myStreamWriter.WriteLine(ControlChars.Tab & message.Action)

 ' Print to the log file the type of the client that invoked
 ' the XML Web service method.
 myStreamWriter.WriteLine("The type of the client is: ")
 If message.Client.GetType().Equals(GetType(MathSvc)) Then
    myStreamWriter.WriteLine(ControlChars.Tab & "MathSvc")
 End If

' Print to the log file the method invoked by the client.
 myStreamWriter.WriteLine( _
    "The method that has been invoked by the client is:")
 myStreamWriter.WriteLine(ControlChars.Tab & message.MethodInfo.Name)

 ' Print to the log file if the method invoked is OneWay.
 If message.OneWay Then
    myStreamWriter.WriteLine( _
       "The client doesn't wait for the server to finish processing")
 Else
    myStreamWriter.WriteLine( _
       "The client waits for the server to finish processing")
 End If 

 ' Print to the log file the URL of the site that provides 
 ' implementation of the method.
 myStreamWriter.WriteLine( _
    "The url of the XML Web service method that has been requested is: ")
 myStreamWriter.WriteLine(ControlChars.Tab & message.Url)
 myStreamWriter.WriteLine("The contents of the SOAP envelope are: ")
 myStreamWriter.Flush()

 ' Copy the contents of one stream to another. 
 Copy(newStream, myFileStream)
 myStreamWriter.Close()
 myFileStream.Close()
 newStream.Position = 0

 ' Copy the contents of one stream to another. 
 Copy(newStream, oldStream)
