    XML Serialization and SOAP

    I created a piece of code with which I can create an XML which look like this:
    Code:
    <?xml version="1.0" encoding="utf-8"?>
<test xmlns:test="http://www.test.nl">
  <a>A</a>
  <b>
    <c>1</c>
    <c>2</c>
    <c>4</c>
    <c>3</c>
  </b>
</test>
    I did this creating a class using XSD.exe on the following XSD:
    Code:
    <?xml version="1.0" encoding="utf-8"?>
<xs:schema attributeFormDefault="unqualified" elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema">
  <xs:element name="test">
    <xs:complexType>
      <xs:sequence>
        <xs:element name="a" type="xs:string" />
        <xs:element name="b">
          <xs:complexType>
            <xs:sequence>
              <xs:element maxOccurs="unbounded" name="c" type="xs:string" />
            </xs:sequence>
          </xs:complexType>
        </xs:element>
      </xs:sequence>
    </xs:complexType>
  </xs:element>
</xs:schema>

    My question:
    If I want to send this xml as a request to a SOAP server, how do I add the SOAP-envelope?

    I tried to do this:
    1) define a class for the SOAP envelope
    Code:
        [XmlInclude(typeof(SOAP))]
    [Serializable]
    public class SOAP
    {
        public string Head { get; set; }
        public object Body { get; set; }
    }
    When I try to insert my XML thing into this like this:
    Code:
    SOAP x3 = new SOAP { Head = "x1", Body = x2 };
            XmlSerializer xs3 = new XmlSerializer(x3.GetType(), "");
            XmlWriterSettings xws3 = new XmlWriterSettings();
            xws3.Indent = true;
            xws3.Encoding = Encoding.UTF8;
            XmlWriter xw3 = XmlWriter.Create("test3.xml", xws3);
            xs3.Serialize(xw3, x3, namespaces);
    It fails with an 'InvalidOperati onException' on the xs3.Serialize.
    ('x2' is the object holding the XML shown earlier...)

      Could you please paste the contents of here X3 just before the Serialize sentence.

          I made some changes to above code (I will edit my original post too)

          the contents of X3 is (copied from 'Immediate Window':
          Code:
          x3
{CreateXML_1.SOAP}
    Body: {test}
    Head: "x1"
x3.Body
{test}
    a: "A"
    aField: "A"
    b: {string[0x00000004]}
    bField: {string[0x00000004]}
x3.Head
"x1"
          If you was hoping to see something else please give directions on how to get that info... ;)


          BTW: If I change the definition of 'Body' (which is currently an 'object' to 'test' than I do no get the error. But that's not what I want, because I need the possibility to send other XML's to the same server.

          After changing 'object' to 'test', i'm getting this test3.xml:
          Code:
          <?xml version="1.0" encoding="utf-8"?>
<SOAP xmlns:test="http://www.test.nl">
  <Head>x1</Head>
  <Body>
    <a>A</a>
    <b>
      <c>1</c>
      <c>2</c>
      <c>4</c>
      <c>3</c>
    </b>
  </Body>
</SOAP>
          I'm loosing the 'test'-rootTag, which I also do not like ;)

              If I understood your question correctly, there might be some problem the format for the Header contents. Probably you could look into http://stackoverflow.com/questions/2...nvelope-in-net

              Hope this helps.

                  If you are referring to the answer "I was able to solve this by using an XLST to wrap the XML in soap"...

                  This is (I tihkn) a no go, because this would probable be tooo slow. (and to complex to implement (for /me ;)).

                  But i'll give it a test tomorrow.... ;)
