The Console.ReadLine() method in C# is used to read the next line of characters from the standard input stream.SyntaxThe syntax is as follows −public static string ReadLine ();ExampleLet us now see an example to implement the Console.ReadLine() method in C# −using System; public class Demo{ public static void Main(){ string str; Console.WriteLine("Enter any subject..."); str = Console.ReadLine(); Console.WriteLine("Entered subject = "+str); } }OutputThis will produce the following output −Enter any subject... Entered subject = Maths
The Console.Read() method in C# is used to read the next character from the standard input stream.SyntaxThe syntax is as follows −public static int Read ();ExampleLet us now see an example to implement the Console.Read() method in C# −using System; public class Demo{ public static void Main(){ int val; Console.WriteLine("Enter a value"); val = Console.Read(); Console.WriteLine("Entered value: "+val); } }OutputThis will produce the following output. Let’s sayEnter a value Entered value: 53
The Console.MoveBufferArea() method in C# is used to copy a specified source area of the screen buffer to a specified destination area.SyntaxThe syntax is as follows −public static void MoveBufferArea (int sourceLeft, int sourceTop, int sourceWidth, int sourceHeight, int targetLeft, int targetTop);Here, sourceLeft The leftmost column of the source area.sourceTop The topmost row of the source area.sourceWidth The number of columns in the source area.sourceHeight The number of rows in the source area.targetLeft The leftmost ... Read More
The Console.KeyAvailable() property in C# is used to get a value indicating whether a key press is available in the input stream.SyntaxThe syntax is as follows −public static bool KeyAvailable { get; }ExampleLet us now see an example to implement the Console.KeyAvailable() property in C# −using System; using System.Threading; class Demo { public static void Main (string[] args) { ConsoleKeyInfo cs = new ConsoleKeyInfo(); do { Console.WriteLine("Press a key to display; "+ "press the 'Q' key to quit."); while (Console.KeyAvailable == false)Thread.Sleep(100); ...
