After such a long time, I re-read C # advanced programming today. I am a little clear about the previously blurred things. Maybe I have recently visited some of the big boys in the garden. Article About It. I once again realized that CLR is in the whole. NET architecture: the core of the entire. NET Framework. Simply put, all Source code (Including all languag

Introduction: Microsoft's. NET platform is a new generation of Internet platform. For technical developers,. The two features of the net platform are remarkable, first of all, the common language runtime, the common language runtime platform, and the large and comprehensive unified programming class. The C # language is a Microsoft company target.

streams through the control flow. "Futures are a substitute for computing results that were initially unknown but subsequently available. The computing process of the results can occur in other computing processes in parallel ." Dynamic Task parallelism, a so-called recursive decomposition, helps to add dynamically created tasks during computation. Pipelines: This mode combines the concept of parallel tasks and concurrent queues, allowing the program to execute tasks concurrently on top of da

The ulong type is a 64-bit unsigned integer with a value range between 0 ~ 18,446,744,073,709,551,615. Both VB and C programmers may be surprised by the new range represented by the int and long data types. In C #, the int no longer depends on the size of the word (word) of a

Errors and failures always occur in applications. If someone adds a new folder on the MDB directory and updates the directory tree of the server, what will happen? What if the MDB name is changed? What if the MDB file is damaged? Each of the above problems will block successful data connection and lead to a failure page. Good programming practices show that you need to be cautious with any failures as much as possible.Before discussing the actual comm
