error with web service call

[=?Utf-8?B?QWNl?=]

hi all,
we are trying to hook up with a web service provided by one of our vendors.
i got their wsdl file and generated a proxy class using wsdl.exe. below is
the method signature as well as the class associated with it:

public partial class WSProxy :
System.Web.Services.Protocols.SoapHttpClientProtoc ol
{
....
public MyArray SearchThis([System.Xml.Serialization.XmlElementAttribute(Form
= System.Xml.Schema.XmlSchemaForm.Unqualified, IsNullable = true)] string
SearchName)
{
object[] results = this.Invoke("SearchNow", new object[] {
SearchName});
return ((MyArray)(results[0]));
}
}

public partial class MyArray : Array
{
}

public partial class Array
{

private System.Xml.XmlElement[] anyField;

.....
}
and here is how i consume this method on my code.

try
{
private WSProxy proxy = new WSProxy();
myArray oArray = new myArray();
oArray = proxy.searchThis(strSearchName);
}
catch (Exception e)
{
throw e;
}

it looks simple to me; however, i am getting the following error:

message: "There is an error in XML document (2, 347)."
inner exception: "The specified type was not recognized: name='Array',
namespace='http://schemas.xmlsoap.org/soap/encoding/', at <SearchResult
xmlns=''>."

any suggestions?

thanks...a

For one thing, I'd suggest your vendor not use the word "Array" as a type
name!

I'd like to see all or part of the WSDL, though. In particular, I'm
wondering where all the XML namespaces are.
