The Uri.IsHexEncoding() method in C# determines whether a character in a string is hexadecimal encoded.SyntaxFollowing is the syntax −public static bool IsHexEncoding (string pattern, int index);Above, the pattern parameter is the string to check, whereas the index is the location in pattern to check for hexadecimal encoding.ExampleLet us now see an example to implement the Uri.IsHexEncoding() method −using System; public class Demo {    public static void Main(){       string pattern = "%50";       bool res = Uri.IsHexEncoding(pattern, 0);       if (res)          Console.WriteLine("Valid: Hexadecimal Encoded");       else   ...

The Uri.IsBaseOf() method in C# is used to determine whether the current Uri instance is a base of the specified Uri instance.SyntaxFollowing is the syntax −public bool IsBaseOf (Uri uri);Above, the parameter Uri is the specified Uri instance to test.ExampleLet us now see an example to implement the Uri.IsBaseOf() method −using System; public class Demo {    public static void Main(){       Uri newURI1 = new Uri("https://www.tutorialspoint.com/index.htm");       Console.WriteLine("URI = "+newURI1);       Uri newURI2 = new Uri("https://www.tutorialspoint.com/");       Console.WriteLine("URI = "+newURI2);       if(newURI1.Equals(newURI2))          Console.WriteLine("Both the URIs ...

The MathF.Pow() method in C# is used to compute a number raise to the power of another number.SyntaxFollowing is the syntax −public static float Pow (float val1, float val2);Above, val1 is the floating-point number raised to a power. The val2 parameter is the power or exponent.ExampleLet us now see an example to implement the MathF.Pow() method −using System; public class Demo {    public static void Main(){       float val1 = 5.00f;       float val2 = 3.00f;       Console.WriteLine("MathF.Pow() = "+MathF.Pow(val1, val2));    } }OutputThis will produce the following output −MathF.Pow() = 125ExampleLet us ...

To change the CursorSize of the Console in C#, use the Console.CursorSize property in C#.ExampleLet us see an example −using System; class Demo {    public static void Main (string[] args) {       Console.BackgroundColor = ConsoleColor.Blue;       Console.WriteLine("Background color changed = "+Console.BackgroundColor);       Console.ForegroundColor = ConsoleColor.Yellow;       Console.WriteLine("Foreground color changed = "+Console.ForegroundColor);       Console.CursorSize = 1;       Console.WriteLine("CursorSize = "+Console.CursorSize);    } }OutputThis will produce the following output −

To change the CursorLeft of the Console in C#, use the Console.CursorLeft property.ExampleLet us see an example −using System; class Demo {    public static void Main (string[] args) {       Console.BackgroundColor = ConsoleColor.Blue;       Console.WriteLine("Background color changed = "+Console.BackgroundColor);       Console.ForegroundColor = ConsoleColor.Yellow;       Console.WriteLine("Foreground color changed = "+Console.ForegroundColor);       Console.CursorLeft = 30;       Console.Write("CursorLeft position: "+Console.CursorLeft);    } }OutputThis will produce the following output −

To change the Foreground Color of text, use the Console.ForegroundColor property in C#.ExampleLet us see an example −using System; class Demo {    public static void Main (string[] args) {       Console.BackgroundColor = ConsoleColor.Blue;       Console.WriteLine("Background color changed = "+Console.BackgroundColor);       Console.ForegroundColor = ConsoleColor.Yellow;       Console.WriteLine("Foreground color changed = "+Console.ForegroundColor);    } }OutputThis will produce the following output −

To change the BufferWidth of the Console, use the Console.BufferWidth property.ExampleLet us now see an example −using System; class Demo {    public static void Main (string[] args){       Console.BufferHeight = 200;       Console.WriteLine("Buffer Height = "+Console.BufferHeight);       Console.BufferHeight = 250;       Console.WriteLine("Buffer Width = "+Console.BufferWidth);    } }OutputThis will produce the following output −Buffer Height = 200 Buffer Width = 200
