title: ASPX to create, read, update, delete SharePoint List
body: <p>I notice a code inside the link - <a href="https://stackoverflow.com/questions/1578361/update-sharepoint-list-item">Update Sharepoint List Item</a> can update the SharePoint List. However, I could not find much information on the following matters:</p>
  
  <p>[1] ASPX code to perform reading of items (based on a criteria) inside SharePoint List. (This include deletion of its parent or children items if it is a lookup field)</p>
  
  <p>[2] ASPX code to perform creating item(s) in SharePoint List.</p>
  
  <p>[3] ASPX code to perform delete of items (based on a criteria) inside SharePoint List.</p>
  
  <p>[4] How to create the above ASPX code (is it inside Visual Studio > ASP.NET Web Application or I can just create a single ASPX file using a notepad)?</p>
  
  <p>[5] Do I need to import SharePoint.dll and what are the steps in creating such web application?</p>
  
  <p>Thanks.</p>
