Complex Expressions in a LINQ Where Clause?

You want the "let" keyword in Linq. Something like this? Var result = from record in xml.Root.

XPathSelectElements("record") let element = record. XPathSelectElement("element@type='sometype'") where (element! = null && element.Value.

Contains("keyword")) select record.

You could use a "let" clause here; from record in xml.Root. XPathSelectElements("record") let element = record. XPathSelectElement("element@type='sometype'") where element!

= null && element.Value. Contains("keyword") select record.

I don't know the query syntax well enough to say for sure, but this would be trivial with the functional syntax: var result = xml.Root. XPathSelectElements("record"). Where(record => { var element = record.

XPathSelectElement("element@type='sometype'"); return (element! = null && element.Value. Contains("keyword")); }).

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
