C# String IsNormalized Method

The String.IsNormalized() method in C# is used to indicate whether this string is in a particular Unicode normalization form.

Syntax

The syntax is as follows −

public bool IsNormalized ();
public bool IsNormalized (System.Text.NormalizationForm normalizationForm);

Above, the parameter normalizationForm is a Unicode normalization form.

Example

Let us now see an example −

 Live Demo

using System;
public class Demo {
   public static void Main(String[] args) {
      string str1 = "Ryan";
      string str2 = "Matt";
      Console.WriteLine("String 1 = "+str1);
      Console.WriteLine("HashCode of String 1 = "+str1.GetHashCode());
      Console.WriteLine("Index of character 'k' in str1 = " + str1.IndexOf("k"));
      Console.WriteLine("
String 2 = "+str2);
      Console.WriteLine("HashCode of String 2 = "+str2.GetHashCode());
      Console.WriteLine("Index of character 'k' in str2 =" + str2.IndexOf("k"));
      bool res1 = str1.Contains(str2);
      res1 = str1.IsNormalized();
      Console.WriteLine("
The str1 is in normalized form = "+res1);
      bool res2 = str1.Contains(str2);
      res2 = str2.IsNormalized();
      Console.WriteLine("The str2 is in normalized form = "+res2);
   }
}

Output

This will produce the following output −

String 1 = Ryan
HashCode of String 1 = 1580592915
Index of character 'k' in str1 = -1
String 2 = Matt
HashCode of String 2 = -1920007383
Index of character 'k' in str2 =-1
The str1 is in normalized form = True
The str2 is in normalized form = True

Example

Let us now see another example −

 Live Demo

using System;
using System.Text;
public class Demo {
   public static void Main(String[] args) {
      string str1 = "Imagine Dragons";
      string str2 = "Imagine";
      Console.WriteLine("String 1 = "+str1);
      Console.WriteLine("HashCode of String 1 = "+str1.GetHashCode());
      Console.WriteLine("String 2 = "+str2);
      Console.WriteLine("HashCode of String 2 = "+str2.GetHashCode());
      Console.WriteLine("String 1 is equal to String 2: {0}", str1.Equals(str2));
      Console.WriteLine("str1 is normalized to form C? = {0}",
      str1.IsNormalized(NormalizationForm.FormC));
      Console.WriteLine("str2 is normalized to form C? = {0}", (str2.IsNormalized(NormalizationForm.FormC)));
      Console.WriteLine("str1 is normalized to form D? = {0}", str1.IsNormalized(NormalizationForm.FormD));
      Console.WriteLine("str2 is normalized to form D? = {0}", str2.IsNormalized(NormalizationForm.FormD));
      Console.WriteLine("str1 is normalized to form KC? = {0}", str1.IsNormalized(NormalizationForm.FormKC));
      Console.WriteLine("str2 is normalized to form KC? = {0}", str2.IsNormalized(NormalizationForm.FormKC));
      Console.WriteLine("str1 is normalized to form KC? = {0}", str1.IsNormalized(NormalizationForm.FormKC));
      Console.WriteLine("str2 is normalized to form KC? = {0}", str2.IsNormalized(NormalizationForm.FormKC));
   }
}

Output

This will produce the following output −

String 1 = Imagine Dragons
HashCode of String 1 = -1546868095
String 2 = Imagine
HashCode of String 2 = -1414695254
String 1 is equal to String 2: False
str1 is normalized to form C? = True
str2 is normalized to form C? = True
str1 is normalized to form D? = True
str2 is normalized to form D? = True
str1 is normalized to form KC? = True
str2 is normalized to form KC? = True
str1 is normalized to form KC? = True
str2 is normalized to form KC? = True
