How to extract Guid from file name?

Question

I want to extract Guid from this below string array and want output like this:

Output:Log.txt,Logging.txt

string[] str = new string[] { "1250a2d5-cd40-4bcc-a979-9d6f2cd62b9fLog.txt", "bdb31966-e3c4-4344-b02c-305c0eb0fa0aLogging.txt" }; //file name are Log.txt and Logging.txt
List<string> list= new List<string>();
foreach (var item in str)
{
    if (!string.IsNullOrEmpty(item))
    {
        list.Add();  // here i want to store Log.txt and Logging.txt
    }
}

How to do this??

`list.Add("Log.txt")` :) – Jacob Seleznev Oct 27 '15 at 04:48 — Jacob Seleznev, Oct 27 '15 at 04:48

var str = new string[] { "1250a2d5-cd40-4bcc-a979-9d6f2cd62b9fLog.txt", "bdb31966-e3c4-4344-b02c-305c0eb0fa0aLogging.txt" }; //file name are Log.txt and Logging.txt

var arr = str.Select(s=>s.Substring(36)).Where(s=>s.Any()).ToArray();

GUIDs are 128 bits, or 32 characters in hex. In that particular representation there's 4 extra dashes -- makes 36! – Blindy Oct 27 '15 at 12:40
