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


              1
            
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


              12345678910
            
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


              1234567891011
            
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


              1234567891011
            
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


              123456789101112
            
namespace ConsoleApp
{
    internal class Program
    {
        static void Main(string[] args)
        {
            System.Console.Write("Hello, ");
            System.Console.WriteLine("World!");
            System.Console.Write("A new line!");
        }
    }
}

Everything was clear?
