To use an instance of ihostingenvironment, it must be injected into the controller (Ihostingenvironment is registered by the system by default and cannot be explicitly registered). Through my experiments, I c

In the brave adventure game, the fastest way to make money is to constantly challenge the level, complete the three-star pass and complete more tasks to achieve the corresponding achievements, in this way, you can get a lot of gold coins and diamonds. Try to use up your physical strength every day.After making money, you also need to upgrade your character skills appropriately so that you can continuously improve your combat power and ensure that you

through the DataGrid. Each order contains a lot of relevant data, including the Order of goods, order time, the buyer's information (name, address, etc.), the buyer's choice of delivery methods. Displaying all this information in a DataGrid (for each order) will result in an excessive display of information. As seen in the DataGrid Web Control Depth Adventure (2), we can specify the columns that need to be displayed by setting the AutoGenerateColumn

The ASP.net DataGrid Web control displays database information in an HTML table and is powerful. In the simplest case, the DataGrid displays the HTML table frame, but it can be enhanced to display a rich user interface, sorted by database columns, and even allows pagination of database results!

In the Gxpt_uas system, to implement files (files and pictures, etc., can be flexibly configured) batch upload to MongoDB, in the process of learning, learning MongoDB, and realize the function of batch upload, realize the idea: On the basis of DWZ reference to the official examples with the existing GXPT to achieve, during the period read a lot of blogs, for these frameworks, the main study or should be based on document guidance, more look at the official manual (even if the document is very s

In addition, the maven plug-in mechanism is completely dependent on the maven lifecycle, so it is critical to understand the lifecycle. In subsequent articles, I will further explain the maven plug-in mechanism. Summary Just getting started, we still need to gradually gain a deep understanding in the project, learn from giants, and grow faster than others. The learning of

In the gxpt_uas system, files (files and images can be flexibly configured) must be uploaded to mongodb in batches. In the process of learning this, I learned mongodb, the batch upload function is also implemented. The implementation idea is as follows: Based on DWZ, refer to the official instance and use the existing GXPT. During this period, I read a lot of blogs. For these frameworks, the main learning method should be document Guidance. Read more official manuals (even if there are few docum

Finally, we discuss how to define special types such as delegate, structure type, and enumeration type. I believe that with this knowledgeYou can use F # Instead of C # To compile the class library. The process of learning this knowledge also gives us a new perspective on. NET.Framework. After learning the three main programming paradigms of F #, we

This includes functions (first-class citizens, higher-order functions, Gerty, anonymous functions, closures), avoidance of side effects (modification of State and data), recursion, lazy evaluation, pattern matching, and then discusses the effect of FP on code structure.
