Question

I want to remove "2011" and everything before it plus a single space (" ") after "2011".

Not quite sure how to approach this, all I could think of is a simple regex-like find and replace.

string temp;
StringBuilder sb = new StringBuilder();
string[] file = File.ReadAllLines(@"TextFile1.txt");
foreach (string line in file)
{
    if (line.Contains("  "))
    {
        temp = line.Replace("  ", " ");
        sb.Append(temp + "\r\n");
        continue;
    }
    else
        sb.Append(line + "\r\n");
 }
 File.WriteAllText(@"TextFile1.txt", sb.ToString());

I have modified my code and with a bit of luck got it to work. Modifications look as follows:

if (line.Contains("2011"))
   {

   temp = line.Substring(line.IndexOf("2011 ") + 5);


   sb.Append(temp + "\r\n");

   continue;

   }

Answer 1

string s = "653 09-23-2011 21 27 32 40 52 36 ";
s = s.Substring(s.IndexOf("2011 ") + 5);

The result is that s = “21 27 32 40 52 36 “
