Use the matrix3d(n,n,n,n,n,n,n,n,n,n,n,n,n,n,n,n) method to transform the element using 16 values of matrix.Let us see the syntaxmatrix3d(a1, b1, c1, d1, a2, b2, c2, d2, a3, b3, c3, d3, a4, b4, c4, d4)Here, a1 b1 c1 d1 a2 b2 c2 d2 a3 b3 c3 d3 d4 are numbers showing the linear transformationa4 b4 c4 are numbers describing the translation to apply.
With C#, you can manipulate decimals with operators such as _+, - *, etc.Let us see how to subtract decimal values.Firstly, set two decimal values −decimal d1 = 9.5M; decimal d2 = 4.2M;Now to subtract the two values −d1 = d1 - d2;The following is the code −Example Live Demousing System; using System.Linq; class Demo { static void Main() { decimal d1 = 9.5M; decimal d2 = 4.2M; d1 = d1 + d2; Console.WriteLine("Addition of Decimals: "+d1); d1 = d1 - d2; Console.WriteLine("Subtraction of Decimals: "+d1); } }OutputAddition of Decimals: 13.7 Subtraction of Decimals: 9.5
The GetTempPath() method in C# displays temporary file names −Path.GetTempPath();Get the names in a variable and display −string tempFile = Path.GetTempPath();The following is the code −Example Live Demousing System; using System.IO; class Demo { static void Main() { string tempFile = Path.GetTempPath(); Console.WriteLine(tempFile); } }Output/tmp/
To randomize string, firstly use Random class −Random r = new Random();Now, use the Next() method with OrderBy() −string random = new string(str.ToCharArray().OrderBy(s => (r.Next(2) % 2) == 0).ToArray());Here is the compete code that displays randomize string −Example Live Demousing System; using System.IO; using System.Linq; class Demo { static void Main() { const string str = "electronics"; Random r = new Random(); string random = new string(str.ToCharArray().OrderBy(s => (r.Next(2) % 2) == 0).ToArray()); Console.WriteLine("String = {0}", str); Console.WriteLine("Random String = {0}",random); Console.Read(); } }OutputString = electronics Random String = lericsecton
Firstly, set Random class −Random random = new Random();Set a range under the Next() method. This displays a letter between 0 and 26.int a = random.Next(0, 26);Here is the complete code −Example Live Demousing System; using System.IO; using System.Linq; class Demo { static void Main() { Random random = new Random(); // random lowercase letter int a = random.Next(0, 26); char ch = (char)('a' + a); Console.WriteLine(ch); } }Outputt
To match all digits in a string, use C# Regex.Firstly, set a string with digits −string str = "These are my marks: 90 out of 100!";Use the following regular expression to get digits in a string −@"\d+"The following is the code −Example Live Demousing System; using System.Text.RegularExpressions; namespace Demo { class Program { private static void showMatch(string text, string expr) { Console.WriteLine("The Expression: " + expr); MatchCollection mc = Regex.Matches(text, expr); foreach (Match m in mc) { Console.WriteLine(m); ...

To style every checked element, use the CSS :checked selector. You can try to run the following code to implement the :checked selector −ExampleLive Demo input:checked { height: 20px; width: 20px; } Fav sports: Football Cricket Tennis Tennis Output
Use the Regex.Replace method to remove the end part of a string in C#.The following is the string −string s1 = "Demo Text!";Now, let us say you need to remove the exclamation mark (!) from the string. For that just set it to empty using replace −System.Text.RegularExpressions.Regex.Replace(s1, "!", "");Here is the complete code −Example Live Demousing System; using System.Text.RegularExpressions; namespace Demo { class Program { static void Main(string[] args) { string s1 = "Demo Text!"; // replace the end part string s2 = System.Text.RegularExpressions.Regex.Replace(s1, "!", ... Read More
Set a string −string str = "Bit and Bat";Let’s say you need to replace whatever comes inside B and t to A and capitalize the complete string. For that, use Replace −Regex.Replace(str, "B.t", "BAT");Let us see the complete code −Example Live Demousing System; using System.Text.RegularExpressions; namespace Demo { class Program { static void Main(string[] args) { string str = "Bit and Bat"; Console.WriteLine(str); string res = Regex.Replace(str, "B.t", "BAT"); Console.WriteLine(res); } } }OutputBit and Bat BAT and BAT
Set a character with WhiteSpace −char c = ' ';To check if a character is a whitespace character, use the char.IsWhiteSpace method −if (char.IsWhiteSpace(c)) {}Let us see the complete code −Example Live Demousing System; class Demo { static void Main() { char c = ' '; if (char.IsWhiteSpace(c)) { Console.WriteLine("Whitespace character!"); } } }OutputWhitespace character!
