LINQPad – Cool Utility For LINQ
Maybe you know about this, but I saw it first few days a go. I officially in love. LINQPad is a cool little utility that was mainly created to allow you to test LINQ expressions and see them produce a  result and output the results in a nice easy to visualize format. It's great for running LINQ Queries without having to fire up Visual Studio. LINQPad is also a great way to learn LINQ: it comes preloaded with 200 examples from the book," C# 3.0 in a Nutshell " written by Joseph...

Search The File System Using LINQ
Do you want to search a file or file type in the file system? Nice way to do it is using LINQ. var files = from file in new DirectoryInfo( @"D:\temp" ).GetFiles() where file.Name == "MyFile.txt" select file; Or even search after specific file extension : var files = from file in new DirectoryInfo( @"D:\temp" ).GetFiles() where file.Extension == ".txt" select file; Enjoy, Maor

LINQ in Action: Book Review
Recently I got a copy of the book "LINQ in Action " (by Fabrice Marguerie, Steve Eichert, Jim Wooley, and Matt Warren (Foreword))from Manning publishing . Language Integrated Query (LINQ) is a great feature and I wrote about it in this blog . The book targets the .NET developers who know C# (2.0) or VB.NET (8.0): Whether you don't know LINQ or you already know - this book is for you. Read it! For me, it was a pleasure to read it: smooth, clear, didactic and effective. The book divided...

The book...

LINQBridge - Use LINQ to objects in .NET 2.0
I really like LINQ, but what if I want to use it and the target framework is not .NET 3.5? There is a way to use LINQ to Objects in .NET 2.0 projects. LINQBridge makes this possible. I saw it today but I didn't try it yet. (I'll be soon) How it works? First, it's important to understand that C# 3.0 and Framework 3.5 are designed to work with CLR 2.0 -the same CLR version that Framework 2.0 uses. This means that the C# 3.0 compiler emits IL code that runs on the same virtual machine as...

Linq to XML - Adding,Updating and Deleting data
The previous post about Linq to XML introduced how to query XML data using LINQ . LINQ allows us to not only query XML in a truly unique way, but also create XML documents in a very expressive manner. This post will talk about other operations on the XML: adding, updating and deleting data. First, lets create a sample XML document: 1: XElement book = new XElement( "Books" , new XElement( "Book" , 2: new XAttribute( "publisher" , "O'Reilly Media, Inc." ...

Query XML using XLINQ
LINQ to XML is a built-in LINQ data provider that is implemented within the System.Xml.Linq namespace in .NET 3.5. It enables us do the following to XML data: Read. Construct. Write. We can perform LINQ queries over XML from the file-system, from a remote HTTP URL or web-service, or from any in-memory XML content. LINQ to XML provides much richer (and easier) querying and data shaping support than the low-level XmlReader/XmlWriter API in .NET 2 and also much more efficient with usage of much less...

Query types using LINQ
It's great. It's so beautiful. I really like it. Reflecting types using LINQ. How can we do it? We can use Reflection of course, but with LINQ it shortest and simplest. Declare "Type" object , assign the class you want to query and query with LINQ. Example 1: To get all methods of a class: 1: Type tPerson = typeof (Person); 2: var methods = from method in tPerson.GetMethods() 3: select method; 4: 5: Console.WriteLine( "All methods:" ); 6: foreach (var m in methods) 7:...

Getting started with LINQ
Language Integrated Query (LINQ) introducing a standard set of operators that can be used to query several different data stores such as SQL Server and XML. LINQ comes as part of the future revisions of both the C# and VB.NET compilers (VS 2008). LINQ architecture As we see at the figure below, the data to be queried can take the form of XML (LINQ to XML), databases (LINQ-enabled ADO.NET, which includes LINQ to SQL, LINQ to Dataset and LINQ to Entities), objects (LINQ to Objects), and so on. (Click...

SqlMetal for Linq
SqlMetal builds a data access layer in seconds. The output is not just a first generation data access; SqlMetal's output includes all defined relationships (based foreign keys) between your tables. SqlMetal will produce a class for each table and, optionally, classes for all views, stored procedures and user-defined functions. You can also generate strongly typed interfaces for stored procedures and user-defined functions. From the developer point of view, it is now a complete breeze to call either...
