What is the purpose of the ReadLine() method? How would you use it with a variable of type string? How would you use it with a variable of type double?

Question

What will be an ideal response?

Answer 1

You use the ReadLine() method to accept user input from the keyboard. This method accepts all of the characters entered by a user until the user presses Enter. The characters can be assigned directly to a string. For example, the following statement accepts a user's input and stores it in the variable myString:
myString = ReadLine();
If you want to use the data as a string-for example, if the input is a word or a name-then you simply use the variable to which you assigned the value. If you want to use the data as a number, then you must use a conversion method to convert the input string to the proper type, as in:
itemPrice = Convert.ToDouble(myString);
