use the Concat() method to concatenate strings
create some strings
using System;
class MainClass {
public static void Main() {
string myString = "To be or not to be";
string myString2 = "... that is the question";
string myString3 = @" Friends, Romans, countrymen,
lend me your ears";
// display the strings and their Length properties
Console.WriteLine("myString = " + myString);
Console.WriteLine("myString.Length = "
+ myString.Length);
Console.WriteLine("myString2 = " + myString2);
Console.WriteLine
("myString2.Length = " + myString2.Length);
Console.WriteLine("myString3 = " + myString3);
Console.WriteLine
("myString3.Length = " + myString3.Length);
}
}
Is Palindrome
using System;
using System.Text;
public class MainClass {
public static bool IsPalindrome(string s) {
int iLength, iHalfLen;
iLength = s.Length – 1;
iHalfLen = iLength / 2;
for (int i = 0; i <= iHalfLen; i++) {
if (s.Substring(i, 1) !=
s.Substring(iLength - i, 1)) {
return false;
}
}
return true;
}
static void Main(string[] args) {
string[] sa = new string[]{"level", "minim", "radar"};
foreach (string v in sa)
Console.WriteLine("{0} {1}",v, IsPalindrome(v));
}
}

Use HttpUtility.HtmlEncode to encode the input string
using System;
using System.Web;
using System.IO;
class MyNewClass
{
public static void Main()
{
String myString;
Console.WriteLine("Enter a string having '&' or '"' in it: ");
myString=Console.ReadLine();
String myEncodedString;
// Encode the string.
myEncodedString = HttpUtility.HtmlEncode(myString);
Console.WriteLine("HTML Encoded string is "+myEncodedString);
StringWriter myWriter = new StringWriter();
// Decode the encoded string.
HttpUtility.HtmlDecode(myEncodedString, myWriter);
Console.Write("Decoded string of the above encoded string is "+myWriter.ToString());
}
}
Returns a string with non alphanumeric chars converted to the substitute character.
