Question

我正在尝试设置我的Biztalk业务流程发送给WCF的消息的MessageHeader。消息合同在WCF项目中如下所示。

 [MessageContract(IsWrapped = true, WrapperName = "PerformTransformationRequestWrapper", WrapperNamespace="http://www.iasreo.com/integration/servicetypes")]
public class PerformTransformationRequest 
{
    [MessageHeader(Namespace = "http://www.iasreo.com/integration/servicetypes")]
    public string Version { get; set; }
    /// <summary>
    /// 
    /// </summary>
    [MessageHeader(Namespace = "http://www.iasreo.com/integration/servicetypes", MustUnderstand = true)]
    public TransformType TransformType { get; set; }

    /// <summary>
    /// 
    /// </summary>
    [MessageBodyMember(Namespace = "http://www.iasreo.com/integration/servicetypes")]
    public System.IO.Stream Payload { get; set; }
}

TransformType.cs

[DataContract(Namespace = "http://www.iasreo.com/integration/servicetypes")]
public enum TransformType
{
    /// <summary>
    /// Transform to Excel
    /// </summary>
    [EnumMember]
    ExcelTransform = 1,

    /// <summary>
    /// Transform to PDF
    /// </summary>
    [EnumMember]
    PDFTransform = 2
}

我正在创建要以消息分配形状发送给Biztalk的消息，该代码如下所示：

xmlDoc = new System.Xml.XmlDocument();
xmlDoc.LoadXml(@"<ns0:PerformTransformationRequestWrapper xmlns:ns0=""http://www.iasreo.com/integration/servicetypes""><ns0:Payload>GpM7</ns0:Payload></ns0:PerformTransformationRequestWrapper>");

PerformTransformationRequest = xmlDoc;

xpath(PerformTransformationRequest, "/*[local-name()='PerformTransformationRequestWrapper' and namespace-uri()='http://www.iasreo.com/integration/servicetypes']/*[local-name()='Payload']") = System.Convert.ToBase64String(System.Text.Encoding.ASCII.GetBytes(Input.OuterXml));

如何在WCF MessageContract中设置MessageHeaders的Version和TransformType？

Answer 1

您可以设置外发邮件的提升WCF.OutboundCustomHeaders属性

OutboundMessage(WCF.OuboundCustomHeaders) = "...";

您需要提供完整的WCF标头字符串作为参数。
