CodePudding user response:

CodePudding user response:

CodePudding user response:

WriteLine: Output, will display the contents of the Output to the Output device, is to you in the code "1223" Output to the Console, if your program is not the Console, can see this message, in VS the Output through some configuration, can also be Output devices directed to file, database, etc.
ReadLine: input, refers to the standard input device (mouse, keyboard, virtual keyboard, etc.) of the input data, read into the program, for example, if you in the Console program, enter "ABC" + enter, so your application can pass the ReadLine reads to the "ABC",
Input and output is independent of the buffer, so you cannot use the ReadLine reads to WriteLine output data, and, in so doing, there is no meaning, because your program has to know what is the data of WriteLine, why read, directly to the line,

CodePudding user response:

ReadLine is commonly used in the console program..
