It depends on your source data. If it is a List, you can have it like this:

List<WhatEverType> list = new List<WhatEverType>();  // Source data

List<WhatEverType> filtered = list.Where((e) => e.Field == "the value here");  // filtered will contain the filtered list


A predicate is simply a Func<type1, type2, ..., returnType> delegate declaration. In the example above, I used a lambda expression for the predicate which is:

(e) => e.Field == "the value here"
