C# Linq where clause as a variable

by

You need to assembly an Expression<Func<T, bool>> and pass it to the Where() extension method:

Expression<Func<T, bool>> whereClause = a => a.zip == 23456;
var x = frSomeList.Where(whereClause);

EDIT: If you’re using LINQ to Objects, remove the word Expression to create an ordinary delegate.
