When you say

but am unable to read the file

do you mean that the sent mail message has a reference to an attachement that can't be opened?

If so, be sure that in

Attachment attch = new Attachment(sFileName);

sFileName contains a valid file full path (Ie: "C:\some_folder\some_File.txt") and you have almost read permissions to the file, and the content is not blocked by the mail server.

About the @ split, if you need to 'remove' the numeric values from the splitted ones, you can write some thing like

private string RemoveNumbers(string inputString)
{
	// This is untested code
	var returnValue = new StringBuilder();
	const string numbers = "0123456789";
	for (int i = 0; i < inputString.Length; i++)
	{
		if (numbers.IndexOf(inputString.Substring(i, 1)) == -1)
			returnValue.Append(inputString.Substring(i, 1));
	}
	return returnValue.ToString();
}

then change the sentence

string fname = "Dear " + emailIdfname[0].ToString() + "&Family,"

to

string fname = "Dear " + [B]RemoveNumbers([/B]emailIdfname[0][B])[/B] + "&Family,"

Hope this helps
