Instead of REGEX, use string.StartsWith method, something like:
if(str.StartsWith("File type:"))
Console.WriteLine(str.Substring("File type:".Length));
You will get:
Wireshark - pcapng
If you want to get rid of leading/trailing spaces from the resultant string then use string.Trim like:
Console.WriteLine(str.Substring("File type:".Length).Trim());
Or if you just want to get rid of leading spaces then use string.TrimStart like:
Console.WriteLine(str.Substring("File type:".Length).TrimStart(' '));

You should also remove the space after
:.

received Wireshark - pcapng, with empty characters at the beginning

@user2214609, use
string.Trim, check the latest answerWhy don't you just remove File type: from your string:
str = str.Replace("File type: ",string.Empty);
Or you can check if the string starts with File type: and remove that part using string.Remove():
if(str.StartsWith("File type: "){
str=str.Remove(11); //length of "File Type: "
}

This should do the trick:
(?<=^File type: ).*$
so...
var match = Regex.Match("File type: Wireshark - pcapng", @"(?<=^File type: ).*$");
if(match.Success)
{
var val = match.Value;
Console.WriteLine(val);
}
