In C# .NET
I have a string with
PSL44T-VK5VF-2B
PSL-44TVK5-VF2B
PS-L44-TVK-5VF-2B
using regular expression can I get the result format as
XXXXXX-XXXX-XX <- PSL44T-VK5VF-2B
PSL-XXXXXX-XXXX <- PSL-44TVK5-VF2B
XX-XXX-XXX-XXX-2B <- PS-L44-TVK-5VF-2B
XX-L44-XXX-XXX-XX <- PS-L44-TVK-5VF-2B


Your question is not clear. But if you want to filter a list of strings with regular expressions, you can do as follows:
List<string> inputs = new List<string>();
inputs.Add("PSL44T-VK5VF-2B");
inputs.Add("PSL-44TVK5-VF2B");
inputs.Add("PS-L44-TVK-5VF-2B");
var myRegex = new Regex("^PSL-.{6}-.{4}$"); // for PSL-XXXXXX-XXXX
List<string> resultList = inputs.Where(f => myRegex.IsMatch(f)).ToList();
and result:

I have given words like:
general, sports, weather
I want to create a push notification condition like:
condition = "'general' in topics || 'sports' in topics || 'weather' in topics",
How can I do this in one -or two- shot in C# without looping? So I can build a new string and I use it like below:
condition = dynamicCondition,

Try this one:
string input = "general, sports, weather";
string output = string.Join(" || ", input.Split(',').Select(s => $"'{s}' in topics"));
Note: don't forget to using System.Linq

I have the string
"{ "type" : "Stage_FF_Hot_Alerts__c"}"
I want to it be
{ "type" : "Stage_FF_Hot_Alerts__c"}
i.e. I want to remove quotes from start and end. How can I achieve this?

You could use Trim:
var a = "\"{ \"type\" : \"Stage_FF_Hot_Alerts__c\"}\"";
var b = a.Trim('"');
Console.WriteLine(a);
Console.WriteLine(b);
It will remove all leading and trailing quotation marks.
Try it online

You can also use:
var quotedString = "\"hello\"";
var unQuotedString = quotedString.TrimStart('"').TrimEnd('"');

How do I extract title from name as Mr. from Mr.ABC or Dr. from Dr.XYZ or M/S. from M/S. PQR in C#?

I would recommend regex for a clean way to get the title.
Regex regex = new Regex(#"^(Mr|Ms|Dr|Sr)\.");
Match match = regex.Match("Mr.ABC");
Console.WriteLine(match.Value);

You can split the string on '.' and then take the first value.
string str = "Mr.ABC";
string title = str.Spilt('.')[0];

There is no need to use regex.
Use String Split method:
var title = myString.Split('.')[0];

I have a string like below
he/a0h/a0dv/a0jks
I would like to be string become as below.
hehdvjks
Need to remove the "/a0" from the string.

The String.Replace method is what you're looking for, just do a;
String myString = "he/a0h/a0dv/a0jks"
myString = myString.Replace("/a0", "")
It'll return a modified 'myString' with all occurrences of the old value ("/a0") replaced with a new value (blank in this case).
The MSDN reference for String.Replace can be found at:
http://msdn.microsoft.com/en-us/library/fk49wtc1%28v=vs.110%29.aspx

var result = "he/a0h/a0dv/a0jks".Replace("/a0", string.Empty);
