Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.

Remarks

When an XML Web service client adds a SOAP header to an XML Web service method call with the MustUnderstand property set to true, the XML Web service method must set the DidUnderstand property to true;otherwise a SoapHeaderException is thrown.

The Detail property can not be set per the SOAP specificaion for a SoapHeaderException.

Example

[Visual Basic, C#, C++] The following XML Web service client calls the MyWebMethod XML Web service method passing in a SOAP header of Type MyHeader setting the MustUnderstand property to true. If the XML Web service method doesn't set the DidUnderstand property of the MyHeader SOAP header to true, a SoapHeaderException is thrown.
