When a query works on an object that implements IQueryable, the query operators that are used are not coming from the System.Linq.Enumerable class, but from the System.Linq.Queryable class. This class provides all the query operators required by the LINQ query expression pattern implemented using expression trees. The query operators in the Queryable static class do not actually perform any querying. Instead, their functionality is to build an expression tree as an instance of the System.Linq.Expressions.Expression object representing the query to be performed and then pass that Expression object to the source IQueryable for further processing. All the implementations of the query operators provided by the Queryable class return a new IQueryable that augments that expression tree with a representation of a call to that query operator. Thus, when it comes time to evaluate the query, typically because the IQueryable is enumerated, the data source can process the expression tree representing the whole query in one batch. The actual query execution is performed by classes that implement the IQueryable interface, as well as the additional IQueryProvider interface. We ll now see how these two types work together and how to implement them. Getting ready for the implementation With our first implementation, the queries were applied to an instance of the LinqToAmazon.AmazonBookSearch type. This type implements IEnumerable<AmazonBook>. Here is a sample query using the first implementation:

7 ways to compress PDF files in C# , VB.NET | Syncfusion Blogs
25 Apr 2018 ... Downsampling the images will decrease the number of pixels and is possibly the most effective way to reduce PDF file size . The user can control the PDF file size with respect to the quality of the image. PdfCompressionOptions options = new PdfCompressionOptions();

var query = from book in new LinqToAmazon.AmazonBookSearch() where book.Title.Contains("ajax") && (book.Publisher == "Manning") && (book.Price <= 25) && (book.Condition == BookCondition.New) select book;

In the second implementation, we re going to create new types that implement IQueryable and IQueryProvider. The entry point type will be named AmazonBookQueryProvider. This is the class that will implement IQueryProvider. A second class will provide a generic implementation of IQueryable<T>: the Query<T> class. Here is how these two classes will allow us to write the same query as earlier using the second implementation:

var provider = new AmazonBookQueryProvider(); var queryable = new Query<AmazonBook>(provider); var query =

If you make more than one change at the same time, it can be difficult to determine what effect each change had on the application s overall performance Test and Measure After you have changed your application or its configuration, you should test it again to determine what effect your changes have and to allow new performance data to be gathered Performance work often requires architectural or other high-impact changes so thorough testing is critical Your application s test plan should exercise the full range of functionality that your application implements, for all anticipated scenarios and on client machines configured with the appropriate hardware and software If your application uses network resources, you should load these resources so that you can gain accurate measurements for how your application performs in such an environment.

Notice how the query is unchanged. Only the object on which we are performing the query is different. The use of an implicitly typed local variable through the var keyword abstracts away the type of the query s result, but it is different for each implementation. With the first implementation, the type of the result is IEnumerable<AmazonBook>. With the second implementation, the type of the result is IQueryable<AmazonBook>. As we already explained, the difference is that IEnumerable<T> represents an enumeration, while IQueryable<T> represents a query. An instance of a type that implements IQueryable<T> contains all the information needed to execute a query. Think of it as a description of what you want done when the query is enumerated. Overview of IQueryable and IQueryProvider Before we move on to the implementation, let s look at how the IQueryable<T> and IQueryProvider interfaces are defined. Here is the declaration of IQueryable<T>:

interface IQueryable<T> : IEnumerable<T>, IQueryable { }

The above process will allow you to focus on specific performance problems by measuring your applications overall performance against specific goals..

This means that we have to implement the members of the following interfaces:

$ErrorActionPreference = 'SilentlyContinue'

interface IEnumerable<T> : IEnumerable { IEnumerator<T> GetEnumerator(); } interface IEnumerable { IEnumerator GetEnumerator(); } interface IQueryable : IEnumerable { Type ElementType { get; } Expression Expression { get; } IQueryProvider Provider { get; } }
