            // Declare and initialize a variable for the Lists Web Service.
            List_Service.Lists listService = new List_Service.Lists();

            /* Authenticate the current user by passing their default
            credentials to the Web Service from the system credential cache.*/
            listService.Credentials = System.Net.CredentialCache.DefaultCredentials;

            // Set the Url property of the service for the path to a subsite.
            listService.Url = "http://sharepoint/_vti_bin/Lists.asmx";

            // Instantiate an XmlDocument object
            System.Xml.XmlDocument xmlDoc = new System.Xml.XmlDocument();

            /* Assign values to the string parameters of the GetListItems method,
            using GUIDs for the listName and viewName variables*/
            string listName = "{17991794-81BB-494F-9910-CFBF1093A7CF}";
            string viewName = "{7137FFF8-48FF-4C69-8C76-0E3BBD1EA7F9}";
            string rowLimit = "150";

            /*Use the CreateElement method of the document object to create elements
            for the parameters that use XML*/
            System.Xml.XmlElement query = xmlDoc.CreateElement("Query");
            System.Xml.XmlElement viewFields = xmlDoc.CreateElement("ViewFields");
            System.Xml.XmlElement queryOptions = xmlDoc.CreateElement("QueryOptions");

            /*To specify values for the parameter elements (optional), assign CAML fragments
            to the InnerXml property of each element*/
            query.InnerXml = "<Where><Gt><FieldRef Name=\"ID\" />" +
            "<Value Type=\"Counter\">3</Value></Gt></Where>";
            viewFields.InnerXml = "<FieldRef Name=\"Title\" />";
            queryOptions.InnerXml = "";

            /* Declare an XmlNode object and initialize it with the XML response from
            the GetListItems method.*/
            System.Xml.XmlNode nodeListItems = listService.GetListItems(listName,viewName,query,viewFields,rowLimit,queryOptions);
           
            // Loop through each node in the XML response and display each item.
            foreach (System.Xml.XmlNode listItem in nodeListItems)
            {
                label1.Text += listItem.OuterXml;

i've already solved the problem...there is an error from query option. The column doesn't exist in my Events list.

I am running into the same problem. How did you fix this?

I had the same problem. for listName and viewName, put GUID for each. i found the GUID in the sharepoint page URL in the query string. QueryOptions must be updated to include several fields, not left blank.

Web_Reference_Folder.Lists listService = new Web_Reference_Folder.Lists();
listService.Credentials= System.Net.CredentialCache.DefaultCredentials;

XmlDocument xmlDoc = new System.Xml.XmlDocument();

string listName = "{7C344558-7D23-463F-842D-B53020780C52}";
string viewName = "{98D0FEE7-A871-4353-81D8-676027C6B885}";
string rowLimit = "150";

XmlNode ndQuery = xmlDoc.CreateNode(XmlNodeType.Element,"Query","");
XmlNode ndViewFields =
xmlDoc.CreateNode(XmlNodeType.Element,"ViewFields","");
XmlNode ndQueryOptions =
xmlDoc.CreateNode(XmlNodeType.Element,"QueryOptions","");

ndQueryOptions.InnerXml =
"<IncludeMandatoryColumns>FALSE</IncludeMandatoryColumns>" +
"<DateInUtc>TRUE</DateInUtc>";
ndViewFields.InnerXml = "<FieldRef Name='Field1' />
<FieldRef Name='Field2'/>";
ndQuery.InnerXml = "<Where><And><Gt><FieldRef Name='Field1'/>" +
"<Value Type='Number'>5000</Value></Gt><Gt><FieldRef Name='Field2'/>" +
"<Value Type=
'DateTime'>2003-07-03T00:00:00</Value></Gt></And></Where>";
try
{
XmlNode ndListItems =
listService.GetListItems(listName, viewName, ndQuery,
ndViewFields, rowLimit, ndQueryOptions, null);
TextBox1.Text = ndListItems.OuterXml;
}

catch (System.Web.Services.Protocols.SoapException ex)
{
TextBox1.Text = "Message:\n" + ex.Message + "\nDetail:\n" +
ex.Detail.InnerText +
"\nStackTrace:\n" + ex.StackTrace;
}
