Method name ([parameter]);In some cases, the class name can be omitted, if you write the method with the main () function in a class, this time,The class name can be omitted.Cases:1 usingSystem;2 usingSystem.Collections.Generic;3 usingSystem.Linq;4 usingSystem.Text;5 usingSystem.Threading.Task
loop:while (loop condition){Circulation body;}Execution procedure: When the program runs to the while, first determine if the loop condition in the parentheses with the while is true,If it is true, that is to say, return one, then execute the loop body, execute the loop body again, and return toThe loop condition is judged, if it is still true, the loop body is continued, and if it is not, it jumps out of the while loop.In the while loop, there is always a line of code that can change the cycle
1. Absolute path and relative pathAbsolute path: This file can be found directly on my computer by the given path.Relative path: The path of the file relative to the application.Conclusion:We should try to use relative paths in development.2.
