C# – redirect code not working in itemreceiver

csharepoint

how can i redirect to a page from sharepoint?

i have this within the itemadded event receiver for a list:

SPUtility.Redirect("http://mysite", SPRedirectFlags.Default, HttpContext.Current );

but on debugging HttpContext.Current is null so it doesnt do any redirect when a list item is added.

The ItemAdded event occurs asynchronously (i.e. sometime after the item is added). It's executing on a separate thread that doesn't have access to the HttpContext for the current request (and therefore you won't be able to send a response to tell the user's browser to redirect).

This might work in the ItemAdding event receiver - it executes on the same thread that adds the item to a the list. I'm not sure that it's safe to perform a redirect since it might prevent other underlying code to be executed in SharePoint.

This was echoed by Lars Fastrup in one of your previous questions (redirect using itemreceiver sharepoint). Consider implementing the solution he recommends there.

C# – LINQ’s Distinct() on a particular property

What if I want to obtain a distinct list based on one or more properties?

Simple! You want to group them and pick a winner out of the group.

List<Person> distinctPeople = allPeople
  .GroupBy(p => p.PersonId)
  .Select(g => g.First())
  .ToList();

If you want to define groups on multiple properties, here's how:

List<Person> distinctPeople = allPeople
  .GroupBy(p => new {p.PersonId, p.FavoriteColor} )
  .Select(g => g.First())
  .ToList();

Note: Certain query providers are unable to resolve that each group must have at least one element, and that First is the appropriate method to call in that situation. If you find yourself working with such a query provider, FirstOrDefault may help get your query through the query provider.

C# – How would you count occurrences of a string (actually a char) within a string

If you're using .NET 3.5 you can do this in a one-liner with LINQ:

int count = source.Count(f => f == '/');

If you don't want to use LINQ you can do it with:

int count = source.Split('/').Length - 1;

You might be surprised to learn that your original technique seems to be about 30% faster than either of these! I've just done a quick benchmark with "/once/upon/a/time/" and the results are as follows:

Your original = 12s
source.Count = 19s
source.Split = 17s
foreach (from bobwienholt's answer) = 10s

(The times are for 50,000,000 iterations so you're unlikely to notice much difference in the real world.)
