Solution 1

Use StartsWith() and Trim():

C#

...
 if (objReader.ReadLine().Trim().StartsWith("#") == false)
...

This should work just fine. Replace the Console.WriteLine(...) with the appropriate code for what you want to do with the lines of text.

Good luck!

C#

var filePath = "C:\\MyPath\\EmailId.txt";
var fileText = System.IO.File.ReadAllText(filePath);
var lines = fileText.Split(new string[] {Environment.NewLine}, StringSplitOptions.RemoveEmptyEntries);

lines = lines.Select(p => p.Trim())
				.Where(p => !string.IsNullOrWhiteSpace(p) &&
				!p.StartsWith("#", StringComparison.OrdinalIgnoreCase))
				.ToArray();

foreach (var line in lines)
	Console.WriteLine(line);
