I have the following xml Schema:

“<?xml version="1.0" encoding="Windows-1252"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
elementFormDefault="qualified" attributeFormDefault="unqualified">
<xs:element name="Document">
<xs:complexType>
<xs:sequence>
</xs:sequence>
<xs:attribute name="name" type="xs:string" />
</xs:complexType>
</xs:element>
<xs:element name="Folder">
<xs:complexType>
<xs:sequence>
<xs:sequence minOccurs="0" maxOccurs="unbounded">
<xs:element ref="Folder" />
<xs:element ref="Document" />
</xs:sequence>
</xs:sequence>
<xs:attribute name="name" type="xs:string" use="required" />
</xs:complexType>
</xs:element>
</xs:schema>”

I want to pass xml documents into a web service that conforms to this
schema. What I have tried to do is use the xsd /c tool to produce a class
based on the schema then have a method definition as follows:

[WebMethod]
public bool test(Folder test)
{
return true;
}

This only allows me to pass in a folder containing one document. The schema
allows for each folder to contain any number of folders or documents. What
can I do to enable this to work?

Thanks

Hello Nick,

According to the XML Schema you mentioned, I have performed some test on my
local side. It seems the XSD tool will generate the following class
(through xsd.exe /classes schamefile). And the generated Folder class
contains a "Document" and a "Folder1" property. However, both of the two
properties are of Array type. So you can add multiple Documents and Folders
instance as children of a Folder instance. This doesn't violate the XSD
schema you provided. Is this what you get in your test project also?

===================
public partial class Folder {

private Folder[] folder1Field;

private Document[] documentField;

private string nameField;

/// <remarks/>
[System.Xml.Serialization.XmlElementAttribute("Folder")]
public Folder[] Folder1 {
get {
return this.folder1Field;
}
set {
this.folder1Field = value;
}
}

/// <remarks/>
[System.Xml.Serialization.XmlElementAttribute("Document")]
public Document[] Document {
get {
return this.documentField;
}
set {
this.documentField = value;
}
}

/// <remarks/>
[System.Xml.Serialization.XmlAttributeAttribute()]
public string name {
get {
return this.nameField;
}
set {
this.nameField = value;
}
}
}

============================

Thanks for replying. That is exactly what I get with the XSD tool. My issue
is with using the following web service with a windows forms application:
“[WebMethod]
public bool test(Folder test)
{
return true;
}”
By creating a new windows forms project and adding a web reference to this
service, I am unable to pass in a folder that contains multiple sub folders:
“WebReference.Service wr = new WebReference.Service();

WebReference.Folder Folder1 = new WebReference.Folder();”
How would I create sub folders / documents?

Thanks

From the generated class defintion of Folder, it has a Folder1 property of
type Folder[], and a Document property of type Document[].

Say you want to pass the contents of C.

WebReference.Folder myCDrive = new WebReference.Folder();

myCDrive.Folder1 = GetSubDirs("c");
myCDrive.Documents = GetFiles("c");

Where GetSubDirs() is a helper method, using System.IO.Directory class to
get directories, and transform the lot to WebReference.Folder[], and same
for GetFiles().

So now the myCDrive object, which is a top level view of the C directory,
has all subdirs and documents in that folder.

Use recursive directory listing code to populate all the subdirs down to a
specified nesting level if necessary.

Thanks for Ron's input.

Hi Nick,

As Ron mentioned, you can provide multiple subfoldes to the "Folder1"
property, and multiple documents to the "Document" property. e.g

==================
static void SimpleTest()
{
TestService.Service ts = new Service();

Folder folder = new Folder();
folder.name = "root_folder1";

Folder[] subfolders = new Folder[3];
subfolders[0] = new Folder();
subfolders[1] = new Folder();
subfolders[2] = new Folder();

folder.Folder1 = subfolders;

Document[] documents = new Document[3];
documents[0] = new Document();
documents[1] = new Document();
documents[2] = new Document();

folder.Document = documents;

string ret = ts.SendFolder(folder);
.........
}
=====================
