Displaying Output
We can use the System.Console.WriteLine
method to display some text in the console. Following is the syntax for doing that:
main
System.Console.WriteLine("message to output");
Note that we enclose the text in double-quotes ("
). In C#, any textual data is always enclosed in double-quotation marks.
Following is a program which outputs a sentence in the console:
main
namespace TestConsoleApp { internal class Program { static void Main(string[] args) { System.Console.WriteLine("Some text to output in the console."); } } }
The System.Console.WriteLine
method automatically shifts the cursor to the next line so if we use System.Console.WriteLine
again, the text will be outputted in a new line.
main
namespace TestConsoleApp { internal class Program { static void Main(string[] args) { System.Console.WriteLine("This is the first line."); System.Console.WriteLine("This is the second line."); } } }
Another method for outputting messages in the console is System.Console.Write
. It is similar to the System.Console.WriteLine
method. However, it does not shift the cursor to the next line.
main
namespace ConsoleApp { internal class Program { static void Main(string[] args) { System.Console.Write("Hello, "); System.Console.Write("World!"); } } }
The difference between the two methods might become more clear with an example:
main
namespace ConsoleApp { internal class Program { static void Main(string[] args) { System.Console.Write("Hello, "); System.Console.WriteLine("World!"); System.Console.Write("A new line!"); } } }
