how do i extract the last value of every output?

Here is the contents of my text file which consists of a name like "output1" followed by a series of numbers, "output2" followed by a series of numbers and so on separated by a single space...I want to extract last value of every output. How do i do this? ie., I want to extract the value of "output1" as 29.933215(ie. the value just before "output2") and the values of "output2" as 379.983559

• content of text file is as shown below:

Use StreamReader's ReadToEnd Method. This will return a string consisting of your data. Split the string and store it into an array. I think you can proceed from there.

     Dictionary<string, double> dic = new Dictionary<string,double>();
     string[] items = str.Split(" ".ToCharArray(), StringSplitOptions.RemoveEmptyEntries);
     string lastOutput = "";
     for(int index = 0; index < items.Length; index++)
     {
        if(items[index].Contains("output"))
        {
           if(lastOutput.Length > 0 && index > 0)
           {
              dic.Add(lastOutput, double.Parse(items[index - 1]));
           }
           lastOutput = items[index];
        }
     }
     dic.Add(lastOutput, double.Parse(items[items.Length-1]));
