List does not exist error while using GetListItems

Question

I am trying get Data of a list using GetListItems Method of Lists.asmx Here is my code:

XmlDocument objXMLDocument = null;

NetworkCredential credentials = new NetworkCredential("user", "pass", "domain");                

XmlNode resultXml = null;

try
{
    XElement result = null;
    string strResult = "<Result>";
    ListService.Lists objLists = new ListService.Lists();
    objLists.Url = "http://domain:port/_vti_bin/Lists.asmx";
    objLists.Credentials = credentials;
    objLists.proxy=new WebProxy();
    objXMLDocument = new XmlDocument();
    objXMLDocument.LoadXml("<QueryOptions><IncludeMandatoryColumns>FALSE</IncludeMandatoryColumns><Folder>" + "ListName" + "</Folder><ViewAttributes Scope=\"RecursiveAll\" /></QueryOptions>");
    XmlNode objQueryOptions = objXMLDocument.DocumentElement;
    resultXml = objLists.GetListItems("ListName", null, null, null, "100", objQueryOptions, null);
    XElement xresult = GetXElement(resultXml);
    XElement objXElement = xresult.Element(XName.Get("data", "urn:schemas-microsoft-com:rowset"));
    IEnumerable<XElement> objXElementList = (objXElement.Descendants(XName.Get("row", "#RowsetSchema")));

    strResult = strResult + "</Result>";
    result = XElement.Parse(strResult);
    return result;
}
catch (Exception ex) { return null; }

But it throws a Microsoft.sharepoint.soapexception and when I checked for details I got these errors:

List does not exist. The page you selected contains a list that does not exist. It may have been deleted by another user. 0x82000006

Sharepoint server we are using is not in our network, it is in our clients network and we use VPN for development.

I feel like the error is can be due to proxy. In browser when i added the proxy provided by client I was able to access internet but not the sharepoint site, than I selected automatically detect proxy and site appeared.

Also i find this link with same error but not able to understand what is suggested solution is.http://www.sharepoint-answers.com/microsoft/SharePoint-Development/29848065/getlist-wss-list-does-not-exist.aspx

Please suggest what can i do. or is it feasible?

Answer 1

Does the list exists in the root of the site collection or in a sub site?

If the list is in the root than you can call it with: http://yourserver:port/_vti_bin/Lists.asmx

If the list you request is on a subsite you need to call the web service like this http://yourserver:port/SUBSITE/_vti_bin/Lists.asmx
