I performed wsdl on SQL2000 reporting service and have a question regarding
the following proxy class.  Right before render procedure declaration you
have code that looks like html or xml.  What is this, how does compiler and
application interpret at run time, and how do I read it and understand what
I should specify if I were to write something similar.

Also, the public function declaration has a return value of
As <System.Xml.Serialization.XmlElementAttribute("Result",
DataType:="base64Binary")> Byte().
What does this mean?  Thank you.

Hi RJ,

These are the attributes in the <>. They defines how your objects are
serialized to SOAP. You can try to search in MSDN for each attribute name,
like SoapHeaderAttribute, to see what it stands for.

For example, XmlElementAttribute indicates that a public field or property
represents an XML element when the XmlSerializer serializes or deserializes
the object that contains it.

XmlElementAttribute("Result", DataType:="base64Binary")> means the property
will be serialized to an xml element. The name for the element is "Result",
and its value is serialized to a base64Binary string.
