}

public static void CreateFieldExpression()
{
    Animal horse = new Animal();

    // Create a MemberExpression that represents getting 
    // the value of the 'species' field of class 'Animal'.
    System.Linq.Expressions.MemberExpression memberExpression =
        System.Linq.Expressions.Expression.Field(
            System.Linq.Expressions.Expression.Constant(horse),
            "species");

    Console.WriteLine(memberExpression.ToString());

    // This code produces the following output: 
    // 
    // value(CodeSnippets.FieldExample+Animal).species
}
