Threading in C# - Free E-book
Threading in C# Joseph Albahari Last updated: 2011-4-27 Translations: Chinese | Czech | Persian | Russian | Japanese Download PDF Part 1: Getting Started C# supports parallel execution of code through multithreading. A C# client program (Console, WPF, or Windows Forms) starts in a single thread created automatically by the CLR and operating system (the “main” thread), and is made multithreaded by creating additional threads. All examples assume the following namespaces are imported: using System; using System.Threading; class ThreadTest{ static void Main() { Thread t = new Thread (WriteY); t.Start(); for (int i = 0; i < 1000; i++) Console.Write ("x"); } static void WriteY() { for (int i = 0; i < 1000; i++) Console.Write ("y"); }} The main thread creates a new thread t on which it runs a method that repeatedly prints the character “y”. Once started, a thread’s IsAlive property returns true, until the point where the thread ends. Done static void Go(){ if (! Done Done (usually!) Join and Sleep

Data trees and C# in Grasshopper - James Ramsden Understanding how Grasshopper handles data is crucial for taking full advantage of GH’s capabilities. For collections of data, they can either be in the form of lists or trees. A list is a collection of items of data, in a particular order, but with no hierarchical structure. Here is a list of numbers:

.NET Framework 4 The .NET Framework is a development platform for building apps for Windows, Windows Phone, Windows Server, and Microsoft Azure. It consists of the common language runtime (CLR) and the .NET Framework class library, which includes classes, interfaces, and value types that support an extensive range of technologies. The .NET Framework provides a managed execution environment, simplified development and deployment, and integration with a variety of programming languages, including Visual Basic and Visual C#. The documentation for the .NET Framework includes an extensive class library reference, conceptual overviews, step-by-step procedures, and information about samples, compilers, and command-line tools. To locate the information that interests you, see the following list of main topic areas. Provides a comprehensive overview of the .NET Framework and links to additional resources.

patterns & practices Each patterns & practices offering contains a combination of written documentation and re-usable source code. Many also include a reference implementation. As the guidance is being developed it is reviewed and approved by internal Microsoft product teams and by external customers and partners. This produces a solid starting point for your application and a set of proven practices that you can follow with confidence. Many patterns & practices offerings illustrate how to incorporate multiple Microsoft products and technologies into an overall solution. Parameter passing in C# Many people have become fairly confused about how parameters are passed in C#, particularly with regard to reference types. This page should help to clear up some of that confusion. If you have any suggestions for how it can be made clearer, please mail me. Microsoft also has a good page about this topic (which I believe uses exactly the same terminology as this page - let me know if they appear to disagree). Note: Lee Richardson has written a complementary article to this one, particularly for those who learn well with pictures. Basically it illustrates the same points, but using pretty diagrams to show what's going on.

C# In this tutorial, we modify the Grasshopper plugin template to add additional parameters to the spiral component. By: Zach Downey In this tutorial we look at a more steamlined approach to the build/test cycle. C# Tutorial - Serialize Objects to a File While storing information in memory is great, there comes a time your users will have to shut your application down. This means (probably) that you will need to write information to a file at some point, because you will want to store whatever data was in memory. Today, we are going to take a look at a feature built into .NET called Serialization that makes writing and reading data structures to and from a file extremely easy. For this example, let's say I want to create a program that keeps track of all the cars my friends own. I'm going to create two objects to achieve this: Car and Owner. The Car object will store the make, model, and year of the car.

Designing and implementing a Data Warehouse Part I Introduction Business Intelligence has become a buzzword in recent years as a support to decision making. Today we can find several database systems which include data warehousing, online analytical processing (OLAP), and data mining technologies. Data warehousing provides an efficient storage, maintenance, and retrieval of data. Intro to C# Scripting in Grasshopper This tutorial covers the use of the timer block to continuously execute a custom script. By: Zach Downey In this tutorial we recreate the pointAt componet and the divide curve component using C#. In this lesson, we cover control flow in your scripts. We introduce the if-else clause and also touch on the modulo % operator. Nested loops!

Serialize List Tutorial A List can be serialized to the disk. We want to serialize (to a file) a List of objects. The next time the program runs, we get this List straight from the disk. We see an example of BinaryFormatter and its Serialize methods. Serial Communication using C# and Whidbey. Free source code and programming help Introduction In this article, I will give you an introduction on how to do serial port communication on .NET platform using C#. The .NET framework version 2.0 (beta) provides features for serial communication. The framework provides System.IO.Ports namespace. The new framework provides classes with the ability to access the serial ports on a computer, and to communicate with serial I/O devices.
