Read value from ini file with 'File.ReadAllText'

I have some ini file include this string : _DeviceName = #1234. Now I want to get the _DeviceName value that is 1234 but it shows me the full string that is _DeviceName = #1234. I tried this code:

if (File.Exists("inifile.ini"))
{
    if (File.ReadAllText("inifile.ini").Split('\r', '\n').First(st => st.StartsWith("_DeviceName")) != null)
    {
        string s = File.ReadAllText("inifile.ini").Split('\r', '\n').First(st => st.StartsWith("_DeviceName"));

        MessageBox.Show(s);

    }
}

I made an application that implements an INI Reader/Writer. Source code not available just yet, but keep checking back, I will have the source uploaded in a few days ( today is 8/14/13) . This particular INI Reader is CASE SENSITIVE and may need modification for special characters, but so far I have had no problems.

You could add another split to get the value out:

if (File.Exists("inifile.ini"))
{
    if (File.ReadAllText("inifile.ini").Split('\r', '\n').First(st => st.StartsWith("_DeviceName")) != null)
    {
        string s = File.ReadAllText("inifile.ini")
                   .Split('\r', '\n').First(st => st.StartsWith("_DeviceName"))
                   .Split('=')[1];
        MessageBox.Show(s);
    }
}

You can use File.ReadAllLines instead. You may want to look at existing ini file readers if you're doing anything more complex but this should work. As a side note, it's not efficient to make two File.ReadAllText calls so quickly; in most cases it's best to just store the result in a variable).

if (File.Exists("inifile.ini"))
{
   string[] allLines = File.ReadAllLines("inifile.ini");
   string deviceLine = allLines.Where(st => st.StartsWith("_DeviceName")).FirstOrDefault();

   if(!String.IsNullOrEmpty(deviceLine))
   {
      string value = deviceLine.Split('=')[1].Trim();
      MessageBox.Show(value);
   }
}

A dirty way would be to use String.Replace("_DeviceName = #", "")
