Use ILSpy to view the Session. SessionID generation algorithm and sessionid generation algorithm. 　　Reason In InProc mode, asp.net sessions are easy to lose and often need to be logged on again. distributed sharing is not supported. So when we are studying how to implement a native Session in Redis, we wanted to use GUID as the key to store the cookie, and we were wondering whether we could implement the sa

than 100, so the corresponding questions are generated directly. The following class implements efficiency considerations in two scenarios. If traversal is fast, you can directly call AddTest to add one more time. If the query is fast, you can use KindOfTestNeed to extract the query conditions, the results generated by the current code are the same each time. If there is a real library, you can use the Randomization of the query results and the Randomization of the KindOfTestNeed condition to g

Many companies often add their logo to the QR code for commercial purposes. However, if the logo block area is large enough, the QR code Becomes unrecognizable. Is there a way to "empty" the above area in advance (to specifically place the logo), while other areas are dedicated to placing the valid data of the QR code? -- This is the question to be discussed in this article. This article focuses on the advanced application and improvement of QR codes. The main idea isImprove the QR code
