Creating List Item Folder

The following code block will check the given folder name existence, and create the folder, inside the given list. This will also return the Folder object.

 

private SPFolder GetFolder(string folderName, SPWeb web, SPList list)

{

SPListItem item = null ;

      SPQuery sq = new SPQuery ();

// CAML query to search folder      

sq.Query = "<Where>" +

     "<And>" +

            "<Eq>" +

                  "<FieldRef Name='Title' />" +

"<Value Type='Text'>" + folderName + "</Value>" +                                "</Eq>" +

            "<Eq>" +

                  "<FieldRef Name='ContentType' />" +

                  "<Value Type='Text'>Folder</Value>" +

           "</Eq>" +

      "</And>" +

      "</Where>" ;

SPListItemCollection itemCol = list.GetItems(sq);

      if (itemCol.Count > 0)

      {

          item = itemCol[0]; // get the folder item object

     }

      if (item == null ) // if no such folder name found, create

      {

         web.AllowUnsafeUpdates = true ; // important step

          item = list.Items.Add("" , SPFileSystemObjectType .Folder, folderName);

         item["Name" ] = folderName;

   // This is required to be set to see on search results

         item["Title" ] = folderName;

         item.Update();

     }

      return item.Folder;

}

 

Note: It’s very important to set the “web.AllowUnsafeUpdates = true ” for such code level folder creations.
