The Math.Asin() method in C# is used to return the angle whose sine is the specified number. The number is a double value argument.SyntaxFollowing is the syntax −public static double Asin (double val);Above, Val is a number representing a sine. The value of Val must be greater than or equal to -1, but less than or equal to 1.ExampleLet us now see an example to implement Math.Asin() method −using System; public class Demo {    public static void Main(){       double val1 = -0.0;       double val2 = Double.PositiveInfinity;       double val3 = Double.NaN; ...

The Math.Acos() method in C# returns the angle whose cosine is the specified number. This number is a double value argument. SyntaxThe syntax is as follows −public static double Acos (double val);Above, Val is the number representing a cosine, where Val must be greater than or equal to -1, but less than or equal to 1.ExampleLet us now see an example to implement Math.Acos() method −using System; public class Demo {    public static void Main(){       double val1 = -0.0;       double val2 = Double.PositiveInfinity;       double val3 = Double.NaN;       Console.WriteLine("Return ...

The Math.Abs() method in C# is used to return the absolute value of a specified number in C#. This specified number can be decimal, double, 16-bit signed integer, etc.ExampleLet us now see an example to implement the Math.abs() method to return the absolute value of double number −using System; class Demo {    public static void Main(){       Double val1 = 30.40;       Double val2 = Double.MinValue;       Double val3 = Double.MaxValue;       Console.WriteLine("Absolute value of {0} : {1}", val1, Math.Abs(val1));       Console.WriteLine("Absolute value of {0} : {1}", val2, Math.Abs(val2)); ...

Dictionary in C# is a collection of keys and values. It is a generic collection class in the System.Collection.Generics namespace.SyntaxFollowing is the syntax −public class DictionaryAbove, the key parameter is the type of keys in the dictionary, whereas TValue is the type of values.ExampleLet us now create a Dictionary and add some elements −using System; using System.Collections.Generic; public class Demo {    public static void Main(){       Dictionary dict = new Dictionary();       dict.Add("One", "John");       dict.Add("Two", "Tom");       dict.Add("Three", "Jacob");       dict.Add("Four", "Kevin");       dict.Add("Five", "Nathan");   ...

The Convert.ToSByte() method in C# converts the specified string representation of a number to an equivalent 8-bit signed integer, using the specified culture-specific formatting information.SyntaxFollowing is the syntax −public static sbyte ToSByte (string val, IFormatProvider provider);Above, the parameter value is a string that contains the number to convert. A provider parameter is an object that supplies culture-specific formatting information.ExampleLet us now see an example to implement the Convert.ToSByte() method −using System; using System.Globalization; public class Demo {    public static void Main(){       CultureInfo cultures = new CultureInfo("en-US");       String str = "-2";       ... Read More

The Convert.ToDouble() method in C# converts the specified string representation of a number to an equivalent double-precision floating-point number, using the specified culture-specific formatting information.SyntaxFollowing is the syntax −public static double ToDouble (string val, IFormatProvider provider);Above, the value value is a string that contains the number to convert, whereas the provider is an object that supplies culture-specific formatting information.ExampleLet us now see an example to implement the Convert.ToDouble() method −using System; using System.Globalization; public class Demo {    public static void Main(){       String val = "876876, 878";       NumberFormatInfo formatProvider = new NumberFormatInfo();     ...

The DateTime.AddHours() method in C# is used to add the specified number of hours to the value of this instance. This method returns a new DateTime.SyntaxFollowing is the syntax −public DateTime AddHours (double hrs);Above, hrs are the number of hours to be added. The value can be negative to subtract the hours.ExampleLet us now see an example to implement the DateTime.AddHours() methodusing System; public class Demo {    public static void Main(){       DateTime d1 = new DateTime(2019, 11, 2, 9, 0, 10);       DateTime d2 = d1.AddHours(2);       System.Console.WriteLine("Initial DateTime = {0:dd} {0:y}, ...
