reverse a string c# code example
Example 1: c# reverse string
public static string ReverseString(string s)
{
char[] arr = s.ToCharArray();
Array.Reverse(arr);
return new string(arr);
}
Example 2: c# reverse a string
public static void Main(string[] args)
{
string s = "aeiouXYZ";
Console.Write(Reverse(s) );
}
public static string Reverse(string s)
{
var result = new string(s.ToCharArray().Reverse().ToArray() );
return result;
}
------------------------------------------------------Option 2
foreach (int v in values.Select(x => x).Reverse())
{
Console.Write(v + " ");
}
Example 3: reverse string c#
string str = "Hello World!";
string reverse = "";
int length = str.Length - 1;
while(length >= 0)
{
reverse += str[length];
length--;
}
Console.WriteLine(reverse);
Example 4: reverse a string in c#
public void ReverseString(char[] s) {
for(int i = 0; i < s.Length / 2; i++) {
char temp = s[i];
s[i] = s[s.Length - 1 - i];
s[s.Length - 1 - i] = temp;
}
}
Example 5: c# substring reverse
public static string ToReverseString(this string value)
{
return string.Join("", value.Reverse());
}
public static string SubstringReverse(this string value, int indexFromEnd, int length)
{
return value.ToReverseString().Substring(indexFromEnd, length).ToReverseString();
}
Example 6: c# reverse a string and case
using System.Linq;
public class Hello{
public static void Main(){
string inputstring="AbcdeFhiJKl";
char[] arr = new char[inputstring.Length];
int i=0;
foreach (char v in inputstring.Select(x => x).Reverse())
{
if (char.IsUpper(v)) { arr[i]=char.ToLower(v); }else{ arr[i]=char.ToUpper(v);};
i=i+1;
}
string str = new string(arr);
System.Console.WriteLine(str);
System.Console.ReadLine();
}
}
