64-bit platform. NET Framework array limits cannot exceed 2GB size. This limitation is a very big problem for workers who need to use large matrices and vector computing.No matter how much RAM you have, once you work with large matrices and vectors, you often throw a System.OutOfMemoryException exception, as shown in:Reference Programclass program { privatestaticvoid Main (string[] args) {

However, if possible, you 'd better get rid of old habits and adopt the new. NET system class. Why? Because the use of the system class makes it easier fo

I recently read the source code of an ERP development framework. I have a deep understanding of the development framework, and I can't help myself with the flexibility of using knowledge points. Professor Lang Xianping said that international financial speculators cannot imagine how to understand and use international financial knowledge. In the Asian financial crisis in 1997, international financial specul

of the XMLDOM subtree. The Xmldom class (The XmlDocument class in the. NET framework) supports XPath-based methods, such as selectnodes methods and selectSingleNode methods. The purpose of these methods is to put the matching nodes in memory. If you need to deal with all the nodes in the subtree, the node browser is more efficient than the incremental approach to processing the nodes ' browsing:XMLDOMNode

. NET Framework | notes | programs | Design 3.4 Reference Strong-named assemblies 1, the second chapter refers to the use of CSC.exe/reference command-line switches to specify the desired referenced assembly file name. If the file name contains the full path, CSC.exe loads the file under the specified path. If you specify a file without a path, it looks for a referenced assembly in the following directory:

C # Delegate and event (2): Use EventArgs and EventHandler In the. Net Framework, As mentioned in the previous article, events are associated through delegation, and delegation can contain various parameters, in which event parameters (EventArgs) can be used. At the same time, it can also be used. net

CLR is the Microsoft ' s implementation of Cli. Apart from scripted languages like JavaScript and VBScript, the. NET Framework presently supports three compiled languages , Namely:VB.NET, VC + + and C # (pronounced C Sharp) language compilers target this runtime. The type verifiable compiler ' s output is called Managed Code. Unsafe codes can also be generated by compilers, which is called unmanaged code.G

ASP. NET mvc3 began to use razor as its view engine, replacing the original ASP. NET web form engine. I recently studied the implementation of razor in mvc3, and found a starting point to allow us to customize the view parsing Engine Based on razor syntax. It can be used in projects, such as mail template customization. Currently, it is only a demo version and is still being improved. Codeplex: http://codeo

Through the previous article, I believe that you have a basic understanding of Quartz. Net and can establish the simplest service. This article describes how to set Trigger conditions for a service. According to the scenario, I usually encounter the following situations at work: 1. Execute when the service starts This Trigger has been used in the previous example. If you do not need to talk about it, directly add the code. ITrigger trigger = TriggerBu

interface, and all Subject must inherit from CanonicalSubjectBase. If a new Observer wants to monitor the Object, you only need to add this Observer method without changing any line of code in the Subject! In addition, you will find that the Object no longer directly depends on those observers (because the method at the beginning is that the Object must call a method of each Observer, the Translator's note), but only depends on the ICanonicalObserver interface. Although the Observer mode of the

attribute nodes in two ways. The first method is to use the Writestartatribute method to create a new attribute node to update the writer's state. The property value is then set using the WriteString method. After writing, use the WriteEndElement method to finish the node. In addition, you can also use the WriteAttributeString method to create a new attribute node, when the state of Writerr is element, writerattributestring start work, it creates a single attribute. Similarly, the WriteStartEle

In the previous article, we mainly introduced mvc3 and project creation. In this article, we will mainly look at the creation of the Entity Data Model in mvc3. When creating a project, we use. net 4, in. in net 4, we can use Entity Framework (Entity Framework) to create models, so as to prepare us for adding, deleting,

I. Basic concepts:In traditional cases, http: // localhost/default. aspx indicates the request for the default. aspx file under the root directory of the website.In ASP. net mvc, routing processes all requests, and then determines the Controller name, action name, and various parameters from the request URL.The Controller executes the corresponding action, and the action processing logic or redirection. By default, No xxx. aspx file request is execute
