    copied!<p>I am writting a winforms c# 2.0 application that needs to put an XML file into a document library on SharePoint. </p> <p>I want to use a WebService instead of using the object model (no sharepoint.dll to reference here) </p> <p>I am currently using the <a href="http://webserver/site/_vti_bin/copy.asmx" rel="noreferrer">http://webserver/site/_vti_bin/copy.asmx</a> webservice.</p> <p>Here is some code: </p> <pre><code>byte[] xmlByteArray; using (MemoryStream memoryStream = new MemoryStream()) { xmlDocument.Save(memoryStream); xmlBytes = memoryStream.ToArray(); } string[] destinationUrlArray = new string[] {"http://webserver/site/Doclib/UploadedDocument.xml"}; FieldInformation fieldInfo = new FieldInformation(); FieldInformation[] fields = { fieldInfo }; CopyResult[] resultsArray; using (Copy copyService = new Copy()) { copyService.Credentials = CredentialCache.DefaultCredentials; copyService.Url = "http://webserver/site/_vti_bin/copy.asmx"; copyService.Timeout = 600000; uint documentId = copyService.CopyIntoItems("", destinationUrlArray, fields, xmlByteArray, out resultsArray); } </code></pre> <p>When this code runs, I get a single result in the resultsArray out parameter: </p> <pre><code>DestinationURL: "http://webserver/site/Doclib/UploadedDocument.xml" ErrorCode: UnKnown ErrorMessage: "Object reference not set to an instance of an object." </code></pre> <p>From my searching, I have found a couple of possible helps. </p> <ul> <li><p><a href="http://social.technet.microsoft.com/Forums/pt-BR/sharepointdevelopment/thread/5a1ce3c9-ebc7-4ec9-b0fb-b891d076591b" rel="noreferrer">Microsoft TechNet</a> -- "The copy.asmx copyintoitems will only work if the source and destination urls are in the same SPWebApplication (Site Collection)."</p></li> <li><p><a href="http://social.microsoft.com/Forums/zh-CN/sharepointdevelopment/thread/273528be-b207-48d9-b697-74777416638e" rel="noreferrer">Microsoft Social</a> -- "Object reference not set to an instance of an object error occurs because of SharePoint not able to identified that particular property."</p></li> </ul> <p>This leads me to believe my source url should be set to something, but what? This is originating from a client workstation and does not have a source URL.</p> <p>Any help would be appricated. </p> <p>hank you,<br> Keith </p>
