Solution 1

Make use of SubString and IndexOf as shown below.

string newString = parts[0].ToString().Substring(0, parts[0].ToString().Length - 11);

You can sort out the finer details.

Solution 2

You can use Substring() to do that
Something like following should help-

C#

for(int i=0;i< parts.Length;i++)
      {              
              Console.WriteLine("{0}",parts[i].Substring(0, input.Length-11)); // 11 characters to exclude the date and one whitespace in between
              //you can create another array to store these values now
      }

Hope, it helps :)

There are two ways to do this.
The first is to split the string twice:

C#

string value = "P 2016-10-17,P 2016-10-18,P 2016-10-19,P 2016-10-20,P 2016-10-21";
string[] parts = value.Split(',');
foreach (string part in parts)
    {
    string[] subParts = part.Split(' ');
    if (subParts.Length > 0) Console.WriteLine(subParts[0]);
    }

The second is to use a regex:

C#

string value = "P 2016-10-17,P 2016-10-18,P 2016-10-19,P 2016-10-20,P 2016-10-21";
MatchCollection matches = Regex.Matches(value, @"(?<=^|,)(?<Prefix>.+?)(?=\s)");
foreach (Match m in matches)
    {
    Console.WriteLine(m.Value);
    }

The regex is a little more complex, but a lot more flexible!
