There are tools in Visual Studio, such as Code Analysis, that can analyze your code and inform you of potential problems. Code Analysis has a number of predefined rules that can uncover cases where you haven’t disposed your object, or when you have unused method arguments. Unfortunately, Cod...
A method is compatible with a delegate if the delegate's parameter types are subclasses of the method's parameters, and the method's return type is a subclass of the delegate's return type. In this case, the parameters of the delegate type,MouseButtonEventHandler, are subclasses of the par...

A quick look at the stored procedure shows that none of the parameters are escaped for single quotes and, as such, this is vulnerable to SQL injection attacks. An attacker can pass a few specific arguments and modify the SQL statement to this: 複製 update Users se...

The shell matches arguments containing globs to filenames, substitutes the filenames for those arguments, and then runs the revised command line. The substitution is called expansion because the shell substitutes all matching filenames. Here are some ways to use * to expand filenames: shell将...
The MSIL code for arrays and strings is slightly more complex. Helper methods to read arrays and strings are defined as taking both the BinaryReader and the length as parameters. The length to use is determined while generating the dynamic code, based on a custom attribute specified on the fie...
When I began this article, I cited all the ways that MongoDB and DocumentDB are similar; however, by now you can start to sense that there are actually a number of differences between the two, by way of philosophy behind their construction, if nothing else. Microsoft is clearly looking to...
