Creating Property Set Expression Trees In A Developer Friendly Way
In a previous post I showed how to create expression trees to set properties on an object. The way I did it was not very developer friendly. It involved explicitly creating the necessary expressions because the compiler won’t generate expression trees...
LINQ: Implementing The SkipLastWhile Operator
Following my last posts ( > )( > ), in this post I’ll introduce the implementation of the SkipLastWhile operator. The SkipLastWhile returns all but the last contiguous elements from a a sequence that satisfy the specified criteria and is implemented...
LINQ: Implementing The SkipLast Operator
Following my last post , in this post I’ll introduce the implementation of the SkipLast operator. The SkipLast operator returns all but a specified number of contiguous elements from the end of a sequence and is implemented as the SkipLast extension method...
LINQ: Introducing The Skip Last Operators
After having introduced the TakeLast operators ( > )( > )( > ), it makes sense to introduce their duals: the SkipLast operators. Name Description Example SkipLast<TSource>(IEnumerable<TSource>) Returns all but a specified number of...

LINQ: Implementing The TakeLast Operator
Following my last post , in this post I’ll introduce the implementation of the TakeLast operator. The TakeLast operator returns a specified number of contiguous elements from the end of a sequence and is implemented as the TakeLast extension method :...
