C# Program to Print Hello World Without Using WriteLine Last Updated : 01 Nov, 2021 Comments Improve Suggest changes Like Article Like Report Hello World program is the most basic program of any programming language. It prints "Hello world" on the screen. In this article, we will display "Hello World" without using WriteLine Method. So to do this task we use the following methods: Console.OpenStandardOutput(): This method is used to acquire the standard output stream.Console.ReadKey(): This method is used to get the next character pressed by the user and this press key will be displayed in the console window.BeginWrite(): This method is used to begin an asynchronous write operation.AsyncWaitHandle.WaitOne(): This method is used to wait for an asynchronous operation to complete.For writing Hello World we are taking each separate character in ASCII format and then we are displaying these characters together. StringHello WorldASCII Code721011081081113287111114108100Approach 1. Inside if condition, Write OpenStandardOutput() to display the Hello World. 2. This method is followed by BeginWrite() method that takes integer Bytes. BeginWrite(new byte[] { 072, 101, 108, 108, 111, 032, 087, 111, 114, 108, 100, 0 }, 0, 12, null, null) 3. Finally we are using AsyncWaitHandle.WaitOne() method followed by BeginWrite() method. BeginWrite(new byte[] { 072, 101, 108, 108, 111, 032, 087, 111, 114, 108, 100, 0 }, 0, 12, null, null).AsyncWaitHandle.WaitOne()) Example: C# // C# program to display Hello World without // using WriteLine() method using System; class GFG{ static void Main(string[] args) { // ASCII values for Hello World if (System.Console.OpenStandardOutput().BeginWrite(new byte[] { 072, 101, 108, 108, 111, 032, 087, 111, 114, 108, 100, 0 }, 0, 12, null, null).AsyncWaitHandle.WaitOne()) { } } } Output: Hello World Comment More infoAdvertise with us Next Article C# Program to Print Hello World Without Using WriteLine gottumukkala_sivanagulu Follow Improve Article Tags : C# CSharp-programs Similar Reads Bash Script - Write Hello World Program In this article, we are going to see how to write "hello world" program in Bash script.
