I have a string variable like:
string data= "#FirstName=Arvind #LastName= Chaudhary_009"
Using Regex in C# i Want the output like :

is there some reason you have to use regex here? String.Split(new char[] {' ', '#'}, StringSplitOptions Remove Empty) and then string.Replace("=", " = ") for the specific string example you give. Is there some variability in the input that makes it harder?Sean K– Sean K2016-11-15 02:17:21 +00:00Commented Nov 15, 2016 at 2:17

There would be more ways of doing this. Two of them would be
string data = "#FirstName=Arvind #LastName= Chaudhary_009";
data = data.Replace("_", "");
data = data.Replace("=", " = ");
string[] dt = data.Split(new char[] {'#'}, StringSplitOptions.RemoveEmptyEntries);
Console.WriteLine(dt[0]); // Print your array here
Regex: Which you asked for
Regex regex = new Regex(@"#");
string[] dt1 = regex.Split(data).Where(s => s != String.Empty).ToArray();
Console.WriteLine(dt1[0]); // Print your array here
You can print array the way you want
Edit
After Understanding the requirements from comments
string data = "#FirstName=Arvind #LastName= Chaudhary_009";
data = data.Replace("_", "");
string[] dt = data.Split(new char[] {'#'}, StringSplitOptions.RemoveEmptyEntries);
Regex regex = new Regex(@"#");
string[] dt1 = regex.Split(data).Where(s => s != String.Empty).ToArray();
foreach(string d in dt)
{
//this will print both the line
Console.WriteLine(d);
}
foreach(string d in dt1)
{
//this will print both the line
Console.WriteLine(d);
}

I don't know the exact requirements here but, there are three things missing from your solution. Removing the _ from the last name, changing the second # into a ; and adding a ; at the end

Yeah the requirements are not clear. Whereas I assumed OP used
; for telling that two splits of the string. and Yeah I completely ignored _ in my solution. Lemme fix that.

string data = "#FirstName=Arvind #LastName= Chaudhary_009"; and want FirstName=Arvind; and LastName= Chaudhary009

@Arvindchaudhary: does the code serve you what you were looking for?

If no space between the
= than just ignore that line. |
There will be many solutions. I suggest you use .NET Regex Tester or a similar online tool to help develop a regex that works well.
A simple example regex that will give you some groups:
#FirstName\s*=\s*(.*)\s?#LastName\s*=\s*(.*)_(.*)
Run that and then format up the output based on groups 1, 2, 3.
