different.So I understand that as long as the application is opened, a process will be created. In the. NET Framework, there is a class Process in the System. Diagnostics namespace, which can be used to create a new Process. The following code is used to create a notebook of hello.txt. After running the code, start the task manager and you can find that a notebook process is created.Using System;Using Syst

return value of the MoveToNextAttribute method. The following code is used to visit all the properties of the current node and combine the name of the property and its value with a comma to form a string: ?? if (reader. HasAttributes) ?? while (reader. MoveToNextAttribute ()) ?? BUF = reader. Name ' =\ ' reader. Value ' \ ', '; ?? Reader. Movetoelement (); ?? When you are finished processing the property set, call the Movetoelement method to return the pointer to the element node to which the

Binding to a Derived TypeBinding derived typesAlthough we have focused on interfaces (since that's most relevant in MVC applications), we can alsoUse the Ninject to bind concrete classes.We focus on this interface (which is important in the MVC application) and can also use Ninject to bind the specific classIn the previous section, we showed the bind a concreteclass to itself, but we can also bind a concrete class to a derived class.The previous section has shown how to bind a specific class, bu

After talking about so many theories, we can manually implement a simple IOC framework, which can deepen the theoretical knowledge of IOC. I. Ideas When using the spring. NET Framework, we first need to instantiate the spring. Net container, and then call the GetObject method in the iobjectfactory interface of the

. If you do not know anything or do not know anything, you can leave a message and I will reply immediately, next we will start to study the implementation of the business logic layer. 4. business logic layer (BLL) (1) from the beginning to the present, our database access layer can only be said to be a little bit slow, because we will modify the database access layer later, the code we write is not always the same, but as we write slowly, we will extract a lot of things for encapsulation, so if

For a while, I experienced a new three-tier model tool developed by a friend in the industry-> dynamic software. netCodeGenerator, feel soft. net code generator (also called codematic) is very good, it is very good for the development of three-tier Web projects, I wrote a little bit, but I think that codesmith is also good abroad, which is more convenient for China?ProgramWhat should I do? Let's discuss it! If you feel soft.

Continue with the Notes for the second part mentioned last time: razor view Engine 1. What is razor: Razor is a new view engine provided in mvc3. ASP. the net view engine looks for special elements that contain server commands to process web pages. As we noted earlier, the standard aspx view engine relies on 2.

The previous section introduced the operations on SQL Server and Oracle databases in dataprovider. This section describes the file system support. Dataprovider not only supports SQL Server and Oracle operations, but also supports file operations. Currently, files in Built-in 3 Support objects such as XML, text, and config, which are located in the xmlprovider, textprovider, and suitconfigprovider class libraries. You can call them by yourself. Most

Permissions objects As. NET security two important branches, role-based security and code access security are inseparable from an important concept-privilege (permissions). In role-based security, the PrincipalPermission class is used to check the user identity of the calling thread, whereas in code access security, a class derived from CodeAccessPermission is used to check the respective permissions of all threads executing the current method. Perm

) ;} The automatic report value is achieved. This is a common method that can simplify a lot of C # report coding work. For example, the code at the beginning of this section can be omitted at present. Multi-language Configuration Second, the labels in the report interface are generally static labels, which cannot match the interface of the software system. As a result, the printed report may have different report languages than the user's offset. So far, I have learned two solutions.
