To Display All List Of Items

Open C# Windows Form , write the below code in the button click event.

private void btnSPList_Click(object sender, EventArgs e)
        {
string strSiteAddress = "http://server"; // E.g: "http://pravahaminfo-pc:1234";  

           //SPSite is returning the site collection.
                SPSite rootSite = new SPSite(strSiteAddress);

           //SPWeb is returning top level site
                SPWeb rootWeb = rootSite.OpenWeb();

           // Represents a collection of SPList objects
                SPListCollection listCollection = rootWeb.Lists;

 //Note : Two ways we can display, you can show list by using for loop or foreach 

          for (int i = 0; i < listCollection.Count; i++)
MessageBox.Show("List Follows : " + listCollection[i].ToString());

         // OR

          foreach (SPList list in listCollection)
                    MessageBox.Show("List follows : " + list.ToString());
