It is easy to find a the position of a chr in another string using the below function.

public static int Findstring(string input, string chrtolook)

{

//find the first / in the path string

int ret = 0;

for (int i = input.Length - 1; i >= 0; i--)

{

if (input.Substring(i, 1) == chrtolook)

{ ret = i + 1; break;

}

}

return ret;

}

public static DateTime ConvertFromUnixTimestamp(long timestamp)

{

DateTime origin = new DateTime(1970, 1, 1, 0, 0, 0, 0, DateTimeKind.Utc);

return origin.AddMilliseconds(timestamp);

}

public static string readTextFile(string sFiletoread)

{

string sRetText = "";

try

{

using (StreamReader sr = new StreamReader(sFiletoread))

{

sRetText = sr.ReadToEnd();

}

}

catch (Exception e)

{

Console.WriteLine(e.ToString()); sRetText = e.ToString();

}

return sRetText;

}
