Use the Console.WindowWidth Property to change the WindowWidth of the Console.ExampleLet us now see an example −using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; class Demo { public static void Main (string[] args) { Console.InputEncoding = Encoding.ASCII; Console.WriteLine("Input Encoding Scheme = "+Console.InputEncoding); Console.OutputEncoding = Encoding.ASCII; Console.WriteLine("Output Encoding Scheme = "+Console.OutputEncoding); Console.CursorVisible = false; Console.Write("Cursor is Visible? "+ Console.CursorVisible); Console.WindowWidth = 30; Console.Write("WindowWidth = "+Console.WindowWidth); } } OutputThis will produce the following ... Read More
Use the Console.WindowTop Property to change the WindowTop of the Console in C#.ExampleLet us now see an example −using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; class Demo { public static void Main (string[] args) { Console.InputEncoding = Encoding.ASCII; Console.WriteLine("Input Encoding Scheme = "+Console.InputEncoding); Console.OutputEncoding = Encoding.ASCII; Console.WriteLine("Output Encoding Scheme = "+Console.OutputEncoding); Console.CursorVisible = false; Console.Write("Cursor is Visible? "+ Console.CursorVisible); Console.WindowTop = 40; Console.Write("WindowTop = "+Console.WindowTop); } }OutputThis will produce the following ... Read More
The UInt32.Equals() method in C# returns a value indicating whether this instance is equal to a specified object or UInt32.SyntaxFollowing is the syntax −public override bool Equals (object ob); public bool Equals (uint ob);Above, the parameter ob for the 1st syntax is an object to compare to this instance and the parameter ob for the 2nd syntax is the 32-bit unsigned integer to compare to this instance.ExampleLet us now see an example to implement the UInt32.Equals() method −using System; public class Demo { public static void Main(){ uint val1 = 52; uint val2 ...

The UInt32.CompareTo() method in C# is used to compare the current instance to a specified object or UInt32 and returns an indication of their relative values.SyntaxFollowing is the syntax −public int CompareTo (object val); public int CompareTo (uint val;Above, the Val for the 1st syntax is an object to compare. The Val for 2nd syntax is an unsigned integer to compare.The return value is 0 if the current instance is equal to value. It’s less than zero if the current instance is less than Val. The return value is more than zero if the current instance is greater than Val.ExampleLet ... Read More
