SharePoint Dragons

As a follow up to article https://sharepointdragons.com/2012/04/21/how-to-check-if-the-current-user-has-already-created-a-list-item-of-a-certain-content-type/ , based on a reader’s question. This is a slightly updated version of the code that writes the underlying CAML to the console output window, like so:

astro.Log = Console.Out;

By explicitly calling it like so you’re exporting the CAML to a text file:

myconsole.exe > caml.txt

The complete code looks like this:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication4
{
    class Program
    {
        static void Main(string[] args)
        {
            // Open entities context generated by spmetal
            // if a sharepoint context is available, use new AstroDataContext(SPContext.Current.Web.Url) instead.
            using (var astro = new AstroDataContext(“http://astro”))
            {
                var timeItems = (from item in astro.MyMetalList
                                                                        where item.GetType() == typeof(Timecard)
                                                                        select (Timecard) item);

                // Call it like this: myconsole.exe > caml.txt
                astro.Log = Console.Out;               

                // Enter specific user name in lambda expression below, for example using: SPContext.Current.Web.CurrentUser.LoginName
                int occurrences = timeItems.Where(item => item.UserName.ToLower() == “loisandclark\\administrator”).Count();
                if (occurrences == 0)
                {
                    Console.WriteLine(“it’s ok to add a request”);
                }
                else if (occurrences == 1)
                {
                    Console.WriteLine(“a request has already been submitted”);
                }
                else
                {
                    Console.WriteLine(“There are duplicate requests. This is an error, contact the administrator”);
                }

                foreach (var item in timeItems)
                {
                    Console.WriteLine(item.Title);
                }
            }
        }
    }
}

The resulting CAML looks like this:
