Description:
Fix for exception timing in iterators.

CLOSED ISSUE: Updated Enumerable

bdesmet — Sun, 16 Dec 2007 21:16:07 GMT

I've attached an updated sln containing an updated Enumerable. The issue with the current one is that the runtime behavior does not match the one in System.Core when it comes to when argument exceptions are thrown. In the framework version's, it throws an exception immediately upon calling the method with an invalid parameter. With the one currently checked in the exception will be thrown upon the first MoveNext call as it's all in iterator.

I've refactored (extracted into private static methods) the iterator portion of the affected methods so that the behavior matches the "real" one. All unit tests continue to pass.
Comments: Fixed as of Changeset 29220.

Welcome to LINQ-SQO

This project helps you to understand how the Standard Query Operators of LINQ to Objects work. Those operators are a crucial part of the LINQ technology that's part of the .NET Framework 3.5 release, previously code-named "Orcas". For an overview of LINQ, please take a look at http://msdn.microsoft.com/data/ref/linq. The source code included with this project is based on the official specification for the .NET Standard Query Operators and is conform with the Orcas RTM implementation (1.0 RTM).

What are the .NET Standard Query Operators?

See http://community.bartdesmet.net/blogs/bart/archive/tags/LINQ/default.aspx for more information.

Releases

The latest release is version 1.0, updated to be conform with the .NET Framework RTM release. You can find it here: 1.0 RTM. Enjoy!

Notes

For those of you interested in expression trees and how to build your own LINQ query provider, take a look at my LINQ to AD sample. Check out the LINQ to SharePoint project as well, which translates LINQ queries to CAML.
