classes available online; in this article, we are going to discuss some of them. This abstraction has at least three advantages (and each improves the security level ): 1. localized code. 2. make the query structure faster and more reliable-because it can be implemented by abstract code. 3. when built based on security features and used properly, this will effectively prevent the various injection attacks

Using C # in the. NET environment to prevent SQL injection attacks, our solution is: 1, first in the UI input, to control the type and length of data, to prevent SQL injection attacks, the system provides detection of
