You may wish to consult this article first to see how to add a reference to the SharePoint library. This post describes reading from a SharePoint List using ASP.Net.
This example shows how we can define a CAML query to return a set of data from a SharePoint list.
try
{
SPSecurity.RunWithElevatedPrivileges(delegate()
{
using (SPSite site = new SPSite(ConfigurationManager.AppSettings["ApplicationPortal"].ToString()))
{
using (SPWeb oweb = site.OpenWeb())
{
SPList appTrackV2 = oweb.Lists[ConfigurationManager.AppSettings["TrackerV2List"].ToString()];
SPQuery oQuery = new SPQuery();
//Specify row limit defining how many rows (max) you want to return
oQuery.RowLimit = 999;
//specify fields you want to return in dataset here
oQuery.ViewFields = "<FieldRef Name='Client'/><FieldRef Name='Requester'/>";
oQuery.ViewFieldsOnly = true;
oQuery.IncludeMandatoryColumns = false;
oQuery.DatesInUtc = true;
oQuery.ViewAttributes = "Scope='RecursiveAll'";
string caml = "";
//caml query to define what we want to return
caml = "<Where><Eq><FieldRef Name='Title'></FieldRef><Value Type='Text'>" + uamid + "</Value></Eq></Where>";
oQuery.Query = caml;
SPListItemCollection collListItems3 = appTrackV2.GetItems(oQuery);
string clientstr = "";
//loop through each item in list and do something
foreach (SPListItem oListItem in collListItems3)
{
clientstr = oListItem["Client"].ToString();
}
}
}
});
}
catch (SPException ex)
{
//Handle Exception
}
