You can create classes that contain code you wish to share across many projects, such as shared business logic, and then reference those classes from different types of projects. Using the Portable Class Library project, you can build portable assemblies that work without modification on the .NET Framework, Silverlight, Windows Phone 7, or Xbox 360 platforms. Without the Portable Class Library project, you must target a single platform and then manually rework the class library for other platforms. The Portable Class Library project supports a subset of assemblies from these platforms, and provides a Visual Studio template that makes it possible to build assemblies that run without modification on these platforms. To create a Portable Class Library project, you must install the following in the specified order: API Differences in Portable Class Library. These changes corrected inconsistencies between the different releases of the types.
You will encounter these changes only when you are working in a Portable Class Library project in Visual Studio 2012. For example, in Silverlight, the System.Net.HttpWebRequest class contains a property named SupportsCookieContainer, but this property did not exist in the System.Net.HttpWebRequest class in the .NET Framework 4. For the Portable Class Library, the SupportsCookieContainer property was added to the .NET Framework to make the types consistent. Partial Class. Partial classes span multiple files.
How can you use the partial modifier on a C# class declaration? With partial, you can physically separate a class into multiple files. This is often done by code generators. Keywords Example. Microsoft .NET Gadgeteer. C# versus JAVA. C# versus JAVA. Für was ist Gas geeignet?
Namespace visibility in C# Java has package scoping.
It allows an element to be visible only within the same namespace. It's a wonderful thing. Here's how it works in Java: package com.pc-doctor.mynamespace; package class Foo { ... } Free C# Compilers and Interpreters. C# is an object-oriented programming language created by Microsoft.

String manipulation (Select where …) C# - Where does System.Diagnostics.Debug.Write output appear? Extension Methods (C# Programming Guide) Extension methods enable you to "add" methods to existing types without creating a new derived type, recompiling, or otherwise modifying the original type.
Extension methods are a special kind of static method, but they are called as if they were instance methods on the extended type. For client code written in C# and Visual Basic, there is no apparent difference between calling an extension method and the methods that are actually defined in a type. DataView RowFilter Syntax. This example describes syntax of DataView.RowFilter expression.
It shows how to correctly build expression string (without „SQL injection“) using methods to escape values. Column names If a column name contains any of these special characters ~( ) # \ /= >< + -* % & | ^' " [ ], you must enclose the column name within square brackets [ ]. If a column name contains right bracket ] or backslash \, escape it with backslash (\] or \\).
Select clause (C# Reference) The document is archived and information here might be outdated In a query expression, the select clause specifies the type of values that will be produced when the query is executed.
The result is based on the evaluation of all the previous clauses and on any expressions in the select clause itself.

A few days ago, one of our readers asked us an interesting question: "is there a place where I can check when does a Windows sound play? ". While we have shown how to customize the sound scheme in Windows, we did not talk about when each system sound is played. That's why we decided to answer this question and detail when each system sound is played by Windows. Let's get started: NOTE: If you want to learn how to change the sounds used by Windows, read this tutorial: How To Customize The Sound Scheme Used On Your Windows Computer.

Log4Net Tutorial pt 3: Appenders. I've discussed using XML to configure lognet, during which I briefly touched on log4net appenders. An appender is an object that persists your log messages someplace. In this post, I'd like to give you a quick overview of the wealth of apppenders available in log4net and show you how you can use them to direct a single log message to multiple places. A Quick Survey Here is a quick sampling of the appenders available in the log4net distribution: There's a lot of them, so to keep this post reasonable I'm focusing on the most basic appenders: the console appenders, debug appenders, and file appenders.
ConsoleAppender and ColoredConsoleAppender These appenders are useful only for console applications, where they provide immediate feedback during program execution. There is one configurable aspect of the ConsoleAppender - the target property identifies what output stream to use when outputting log entries: to the same output from the ColoredConsoleAppender: Blue Green Red Yellow Purple Cyan White.
