Char Struct in C#

Csharp Server Side Programming Programming

The Char Struct in C# represents a character as a UTF-16 code unit. Here are some of the methods −

Method	Description
ConvertToUtf32(Char, Char)	Converts the value of a UTF-16 encoded surrogate pair into a Unicode code point.
ConvertToUtf32(String, Int32)	Converts the value of a UTF-16 encoded character or surrogate pair at a specified position in a string into a Unicode code point.
Equals(Char)	Returns a value that indicates whether this instance is equal to the specified Char object.
Equals(Object)	Returns a value that indicates whether this instance is equal to a specified object.
GetHashCode()	Returns the hash code for this instance.
GetNumericValue(Char)	Converts the specified numeric Unicode character to a double-precision floating-point number.
IsDigit(String, Int32)	Indicates whether the character at the specified position in a specified string is categorized as a decimal digit.
IsLetter(Char)	Indicates whether the specified Unicode character is categorized as a Unicode letter.
IsLetter(String, Int32)	Indicates whether the character at the specified position in a specified string is categorized as a Unicode letter.
sLetterOrDigit(Char)	Indicates whether the specified Unicode character is categorized as a letter or a decimal digit.
IsLetterOrDigit(String, Int32)	Indicates whether the character at the specified position in a specified string is categorized as a letter or a decimal digit.
IsLower(Char)	Indicates whether the specified Unicode character is categorized as a lowercase letter.
IsPunctuation(String, Int32)	Indicates whether the character at the specified position in a specified string is categorized as a punctuation mark.

Let us see an example to implement the Char.IsSymbol() method. The Char.IsSymbol() method in C# is indicated whether the character at the specified position in a specified string is categorized as a symbol character.

Syntax

Following is the syntax −

public static bool IsSymbol (string str, int index);

Above, str is a string, whereas the position of the character to evaluate in str.

Example

Let us now see an example to implement the Char.IsSymbol() method −

Live Demo

using System;
public class Demo {
   public static void Main(){
      bool res;
      char val = 'P';
      Console.WriteLine("Value = "+val);
      res = Char.IsSymbol(val);
      Console.WriteLine("Is the value a symbol? = "+res);
   }
}

Output

This will produce the following output −

Value = P
Is the value a symbol? = False

The Char.IsWhiteSpace() method in C# is used to indicate whether the specified Unicode character is white space.

Syntax

Following is the syntax −

public static bool IsWhiteSpace (char ch);

Above, the parameter ch is the Unicode character to evaluate.

Example

Let us now see an example to implement the Char.IsWhiteSpace() method −

Live Demo

using System;
public class Demo {
   public static void Main(){
      bool res;
      char val = ' ';
      Console.WriteLine("Value = "+val);
      res = Char.IsWhiteSpace(val);
      Console.WriteLine("Is the value whitespace? = "+res);
   }
}
