Unable to run SharePoint internal Web Service "List" from Web Part

ali raza

Hi all, I am new to SharePoint development and stuck with the problem in which i need to run SSharePoint internal web service 'List'. When ever I call the GetList('MyListName') method of this web service I got following exception

Exception of type 'Microsoft.SharePoint.SoapServer.SoapServerException' was thrown.

Followin is the Code that I am using

----------------------------------------------------------------

ListWS.Lists list = new ListWS.Lists();
string strUserId = "administrator";
string strPassword = "123456";

System.Net.NetworkCredential credential = new System.Net.NetworkCredential(strUserId, strPassword, "techerz-01");
list.Credentials = credential;

list.Timeout = System.Threading.Timeout.Infinite;

XmlNode listResponse = list.GetList("Sites");
----------------------------------------------------------------
Any Idea how to get this issue resolve?

In certain situation we need to pass data from webpart to another webpart present in the same site. To implement the connection functionality between WebParts, we should create an Interface .This interface will be implemented by both the provider and consumer classes.

Then we will use the ConnectionProvider and ConnectionConsumer attribute to make the connection between the two webpart.

EXAMPLE:
1. Interface :

    public interface Test
    {
        string Name { get; set; }
    }

Hope you find this tips useful.

Thanks,

First I believe, but could be wrong as I can't test this right now, that your GetList call should be returning a SPList object and not be an XmlNode. Here is a sample from MSDN:

         using (SPSite site = new SPSite("http://localhost/sites/sitecollection"))
         {
            using (SPWeb web = site.OpenWeb("sitecollection/subsite"))
            {
               string listUrl = "/sites/sitecollection/subsite/Lists/Announcements";
               SPList list = web.GetList(listUrl);
               Console.WriteLine("List URL: {0}", list.RootFolder.ServerRelativeUrl);
            }
         }

Since you are running in a webpart on the local server you should be able to use similar code replacing the Console.WriteLine() with appropriate code.
