ASMX [WebMethod] - How to accept multiple document

Question

User1359467950 posted

Hi there,

My schema has  “Documents” element it should contain the “Document” element which should consist of SeqNumber, DocumentId, DocumentType, DocumentContent.

 

 

I am at the moment able to send a single file, but what I need is to send multiple documents.

How do I declare the Documents variable so I’m able to accept more than one document. ?

Could you share us which parameter accepts Documents? Is it DocumentContent?<o:p></o:p>

For accepting multiple values, I think you could try List<T>.<o:p></o:p>

Something like below:<o:p></o:p>

        [WebMethod]
        public string Test(string UserName, [XmlElement(IsNullable =true)] List<byte[]> DocumentContent)

Best Regards,<o:p></o:p>

Forgive me but I don't understand. 

The XSD shows that the Parent element is called "Documents" (shouldn't I name the List "Documents" then?  List<byte[]> Documents ???

The XSD shows that the child elements are SeqNumber, DocumentId, DocumentType, DocumentContent

Now One "Documents" element may contain multiple "Document" element which  consists of SeqNumber, DocumentId, DocumentType, DocumentContent

How do I receive 100 documents in one batch and not lose control on which is which ? How do I creacte a variable that will allow to accept 1 or more Documents ?

Kind regards

Hi,

Could you share us how you upload one file in your original scenario?

A simple project with client ans asmx service would be much helpful.

We will try to modify your current code to achieve your requirement.

Hi,

My understanding is that you transmit only a single DocumentContent so it should be a list or a an array of byte[]. Name this DocumentContents maybe.

I assume you would then use this content all along with other data to create each document (make sure to not confuse the document and its content)...
