SoapDocumentMethodAttribute.OneWay SoapDocumentMethodAttribute.OneWay SoapDocumentMethodAttribute.OneWay SoapDocumentMethodAttribute.OneWay Property

Definition

Gets or sets whether an XML Web service client waits for the Web server to finish processing an XML Web service method.

public:
 property bool OneWay { bool get(); void set(bool value); };
public bool OneWay { get; set; }
member this.OneWay : bool with get, set
Public Property OneWay As Boolean

Property Value

true if the XML Web service client does not wait for the Web server to completely process an XML Web service method. The default value is false.

Examples

The following code example is an XML Web service method that does not require the client to wait for the XML Web service method to complete. Therefore, the sample sets the OneWay property to true.

Remarks

When an XML Web service method has the OneWay property set to true, the XML Web service client does not have to wait for the Web server to finish processing the XML Web service method. As soon as the Web server has deserialized the SoapServerMessage, but before invoking the XML Web service method, the server returns an HTTP 202 status code. A HTTP 202 status code indicates to the client that the Web server has started processing the message. Therefore, an XML Web service client receives no acknowledgment that the Web server successfully processed the message.

One-way methods cannot have a return value or any out parameters.

If you are using the .NET Framework version 1.0 XML Web service methods that have either the SoapRpcMethodAttribute or SoapDocumentMethodAttribute attribute applied to them with the OneWay property of set to true, do not have access to their HttpContext using the static Current property. To access the HttpContext, derive the class implementing the XML Web service method from WebService and access the Context property.
