Why do you want to align the bytes? This is going to start with the structure of the computer, we know that the variables defined in C + + have single-byte (char), double-byte (short), four-byte (Int,float), eight-byte (long), but the CPU is not a

There is something called WMI under windows that can be retrieved. Microsoft has also made a WMI code generation gadget for this purpose.But this thing is really not good to use. The obtained temperature is not refreshed. I recommend using open

C # often uses a time type of variable to tosting, the detailed format is as follows:   d Day of the month.　One-digit date has no leading zeros. DD a day of the month.　A one-digit date has a leading zero.　The abbreviated name of the day of the DDD

predicateGeneric delegate: Represents a method that defines a set of conditions and determines whether the specified object conforms to those conditions. This delegate is used by several methods of the Array and list classes to search for elements
