title: Cannot implicitly convert type 'string' to 'long' with other issue?
body: <p>I have a little problem which I have no clue how to solve. I will give the who;e code from the class so you can see what its doing:</p>
  
  <p>{</p>
  
  <pre><code>class CompetitorDataFile
  {
      //collection of DataFileRecords - people
      public List&lt;DataFileRecord&gt; DataFileRecords;
      public string FileName = "";
  
      //called when DataFile created
      public CompetitorDataFile(string FileName)
      {
          //creates the collection
          DataFileRecords = new List&lt;DataFileRecord&gt;();
          this.FileName = FileName;
      }
  
      //fill DataFileRecords with stuff from text file
      public void ReadDataFile()
      {
          foreach (string s in File.ReadAllLines(FileName))
          {
              if (s == "") continue;
              DataFileRecord dfr = new DataFileRecord();

              dfr.Rank = s.Split(',')[3];

          }
      }
  
      public int FindByCPSA(string CPSA)
      {
          //set index to 0
          int index = 0;
          //go through each record looking for CPSA number match
          foreach (DataFileRecord dfr in DataFileRecords)
          {
              if (dfr.CPSA.ToLower() == CPSA.ToLower())
              {
                  //if it's found return the current index
                  return index;
              }
              //increase index and move to next record

          //create a temporary array of string
          List&lt;string&gt; stringy = new List&lt;string&gt;(DataFileRecords.Count);
          //go through each DataFile record and create a single string line
          foreach (DataFileRecord dfr in DataFileRecords)
              stringy.Add(dfr.SingleString);
          //saves all strings to file
          File.WriteAllLines(FileName, stringy.ToArray());

  </code></pre>
  
  <p>I have a problem with this line of code</p>
  
  <pre><code>dfr.TotalSingleScore = s.Split(',')[12];
  </code></pre>
  
  <p>TotalSingleScore is the only int (all others are strings) as a result I get this error:
  "Error  1   Cannot implicitly convert type 'string' to 'long'"</p>
  
  <p>How do I go about solving this? <strong>Code is C# and software is VS 2008 Pro</strong></p>
  
  <p>Thanks</p>
