Convert.ToBase64String() Method in C#
The Convert.ToBase64String() method in C# is used to convert the value of an array of 8-bit unsigned integers to its equivalent string representation that is encoded with base-64 digits.SyntaxFollowing is the syntax −public static string ToBase64String (byte[] arr);Above, arr is an array of 8-bit unsigned integers.ExampleLet us now see an example to implement the Convert.ToBase64String() method −Using System; public class Demo { public static void Main(){ byte[] val1 = {5, 10, 15, 20, 25, 30}; string str = Convert.ToBase64String(val1); Console.WriteLine("Base 64 string: '{0}'", str); byte[] val2 = ...

The Convert.ToBase64CharArray() method in C# is used to convert a subset of an 8-bit unsigned integer array to an equivalent subset of a Unicode character array encoded with base-64 digits.SyntaxFollowing is the syntax −public static int ToBase64CharArray (byte[] arr, int offsetIn, int length, char[] outArray, int offsetOut);Here, arr − An input array of 8-bit unsigned integers.offsetIn − A position within arr.length − The number of elements of arr to convert.outArray − An output array of Unicode characters.offsetOut − A position within outArray.ExampleLet us now see an example to implement the Convert.ToBase64CharArray() method −using System; public class Demo { public ...
Read MoreConvert.FromBase64String(String) Method in C#
The Convert.FromBase64String(String) method in C# converts the specified string, which encodes binary data as base-64 digits, to an equivalent 8-bit unsigned integer array.SyntaxFollowing is the syntax −public static byte[] FromBase64String (string str);Above, the parameter str is the string to convert.ExampleLet us now see an example to implement the Convert.FromBase64String(String) method −using System; public class Demo { public static void Main(){ byte[] val1 = {5, 10, 15, 20, 25, 30}; string str = Convert.ToBase64String(val1); Console.WriteLine("Base 64 string: '{0}'", str); byte[] val2 = Convert.FromBase64String(str); Console.WriteLine("Converted byte ...
Read MoreCharEnumerator.ToString() Method in C#
The CharEnumerator.ToString() method in C# gets a string that represents the current object.SyntaxFollowing is the syntax -public virtual string ToString();ExampleLet us now see an example to implement the CharEnumerator.ToString() method −using System; public class Demo { public static void Main(){ string strNum = "This is it!"; CharEnumerator ch = strNum.GetEnumerator(); Console.WriteLine("HashCode = "+ch.GetHashCode()); Console.WriteLine("Get the Type = "+ch.GetType()); Console.WriteLine("String representation = "+ch.ToString()); while (ch.MoveNext()) Console.Write(ch.Current + " "); ch.Reset(); Console.WriteLine(); ...
Read MoreMath.Truncate() Method in C#
The Math.Truncate() method in C# is used to compute an integral part of a number, which is Double or Decimal.Syntaxpublic static decimal Truncate(decimal val1) public static double Truncate(double val2)Above, there are two syntaxes. The value val1 is the decimal number to truncate, whereas val2 is the double number to truncate.ExampleLet us now see an example to implement Math.Truncate() method −using System; public class Demo { public static void Main(){ Decimal val1 = 25.46467m; Decimal val2 = 45.9989m; Decimal val3 = 678.325m; Console.WriteLine(Math.Truncate(val1)); Console.WriteLine(Math.Truncate(val2)); ...
Read MoreMath.Tanh() Method in C#
The Math.Tanh() method in C# is used to return the hyperbolic tangent of the specified angle.Syntaxpublic static double Tanh (double val);Above, Val is the angle.ExampleLet us now see an example to implement Math.Tanh() method −using System; public class Demo { public static void Main(){ double val1 = 30.0; double val2 = (60 * (Math.PI)) / 180; Console.WriteLine(Math.Tanh(val1)); Console.WriteLine(Math.Tanh(val2)); } }OutputThis will produce the following output −1 0.780714435359268ExampleLet us see another example to implement Math.Tanh() method −using System; public class Demo { public static void Main(){ ...
