I just create the Web reference to the project for accessing the SharePoint site and get the list of files over there. To accomplish that we have to pass the web reference URL in the below format.
Web service Url Format : "http://Site:Port/_vti_bin/lists.asmx"
using (Lists listProxy = new Lists())
{
listProxy.Url = strURL;
listProxy.UseDefaultCredentials = true;
XmlNode retNode = listProxy.GetListItems(libraryName, string.Empty, queryNode, viewNode, "5000", optionNode, "");
DataSet ds = new DataSet();
using (StringReader sr = new StringReader(retNode.OuterXml))
ds.ReadXml(sr);
if (ds.Tables["Row"] != null && ds.Tables["Row"].Rows.Count > 0)
{
foreach (DataRow dr in ds.Tables["Row"].Rows)
{
XmlNode ndlist = listProxy.GetListAndView(libName, "");
string strBatch = "
"
"
"
"
"
XmlDocument xmlDoc = new System.Xml.XmlDocument();
System.Xml.XmlElement elBatch = xmlDoc.CreateElement("Batch");
elBatch.SetAttribute("OnError", "Continue");
elBatch.SetAttribute("ListVersion", "1");
elBatch.SetAttribute("PreCalc", "TRUE");
elBatch.SetAttribute("ViewName", "{18F11D0B-E5BA-4BFB-90AA-43FFAD6FE112}");
elBatch.InnerXml = strBatch;
XmlNode ndret = listProxy.UpdateListItems(strlistId, elBatch);
strBatch = ndret.OuterXml;
//Check the outerxml if it throws any error skip the check-in process else perform checkin action.
listProxy.CheckInFile(dr["ows_EncodedAbsUrl"].ToString(), "", "1");
}
}
