How to check if two Strings are anagrams of each other using C#?
Under anagram, another string would have the same characters present in the first string, but the order of characters can be different.
Here, we are checking the following two strings −
string str1 = "silent"; string str2 = "listen";
Convert both the strings into character array −
char[] ch1 = str1.ToLower().ToCharArray(); char[] ch2 = str2.ToLower().ToCharArray();
Now, sort them −
Array.Sort(ch1); Array.Sort(ch2);
After sorting, convert them to strings −
string val1 = new string(ch1); string val2 = new string(ch2);
Compare both the strings for equality. If both are equal, that would mean they are anagrams.
The following is the code −
Example
using System;
public class Demo {
public static void Main () {
string str1 = "silent";
string str2 = "listen";
char[] ch1 = str1.ToLower().ToCharArray();
char[] ch2 = str2.ToLower().ToCharArray();
Array.Sort(ch1);
Array.Sort(ch2);
string val1 = new string(ch1);
string val2 = new string(ch2);
if (val1 == val2) {
Console.WriteLine("Both the strings are Anagrams");
} else {
Console.WriteLine("Both the strings are not Anagrams");
}
}
}Output
Both the strings are Anagrams
