Namespace:  System.ServiceModel.Description
Assembly:  System.ServiceModel (in System.ServiceModel.dll)

Use the WsdlContractConversionContext object to examine and modify items that are to be converted to or from WSDL.

When exporting metadata a WsdlContractConversionContext object is passed to the ExportContract and ExportEndpoint methods. Use the various methods and properties to obtain metadata objects that you can use to examine and modify to alter the published WSDL.

When importing metadata a WsdlContractConversionContext object is passed to the ImportContract and ImportEndpoint methods. Use the various methods and properties to obtain metadata objects that you can use to examine and modify the imported metadata.

The following code example shows the use of the WsdlContractConversionContext to add custom WSDL annotations to the exported metadata using the WsdlPortType and Contract properties.


    public void ExportContract(WsdlExporter exporter, WsdlContractConversionContext context)
		{


...


      Console.WriteLine("Inside ExportContract");
			if (context.Contract != null)
			{
        // Inside this block it is the contract-level comment attribute.
        // This.Text returns the string for the contract attribute.
        // Set the doc element; if this isn't done first, there is no XmlElement in the 
        // DocumentElement property.
        context.WsdlPortType.Documentation = string.Empty; 
        // Contract comments.
        XmlDocument owner = context.WsdlPortType.DocumentationElement.OwnerDocument;
        XmlElement summaryElement = Formatter.CreateSummaryElement(owner, this.Text); 
        context.WsdlPortType.DocumentationElement.AppendChild(summaryElement);

        foreach (OperationDescription op in context.Contract.Operations)
        {
          Operation operation = context.GetOperation(op);
          object[] opAttrs = op.SyncMethod.GetCustomAttributes(typeof(WsdlDocumentationAttribute), false);
          if (opAttrs.Length == 1)
          {
            string opComment = ((WsdlDocumentationAttribute)opAttrs[0]).Text;

            // This.Text returns the string for the operation-level attributes.
            // Set the doc element; if this isn't done first, there is no XmlElement in the 
            // DocumentElement property.
            operation.Documentation = String.Empty;

            // Operation C# triple comments.
            XmlDocument opOwner = operation.DocumentationElement.OwnerDocument;
            XmlElement newSummaryElement = Formatter.CreateSummaryElement(opOwner, opComment);
            operation.DocumentationElement.AppendChild(newSummaryElement);

            // Get returns information
            ParameterInfo returnValue = op.SyncMethod.ReturnParameter;
            object[] returnAttrs = returnValue.GetCustomAttributes(typeof(WsdlParameterDocumentationAttribute), false);
            if (returnAttrs.Length == 1)
            {

                  ((WsdlParameterDocumentationAttribute)returnAttrs[0]).ParamComment
                );
              operation.DocumentationElement.AppendChild(returnsElement);
            }

            // Get parameter information.
            ParameterInfo[] args = op.SyncMethod.GetParameters();
            for (int i = 0; i < args.Length; i++)
            {
              object[] docAttrs 
                = args[i].GetCustomAttributes(typeof(WsdlParameterDocumentationAttribute), false);
              if (docAttrs.Length != 0)
              {
                // <param name="Int1">Text.</param>
                XmlElement newParamElement = opOwner.CreateElement("param");
                XmlAttribute paramName = opOwner.CreateAttribute("name");
                paramName.Value = args[i].Name;
                newParamElement.InnerText 
                  = ((WsdlParameterDocumentationAttribute)docAttrs[0]).ParamComment;
                newParamElement.Attributes.Append(paramName);
                operation.DocumentationElement.AppendChild(newParamElement);
              }
            }
