C# Linq where clause as a variable

Question

I am trying to make a LINQ statement where the where clause comes from a variable. For example:

string whereClause = address.zip == 23456;
var x = from somet         


        

Answer 1

This:

var query = from something in someList where whereClause;

is shorthand for:

var query = someList.Where(something => whereClause);

Assuming someList is an IEnumerable

, Where refers to the Enumerable.Where Extension Method. This method expects a Func which you can define as follows:

Func whereClause = address => address.Zip == 23456;
var query = someList.Where(whereClause);
