title: Read and parse a Json File in C#
body: <p>I have spent the best part of two days "faffing" about with code samples and etc., trying to read a very large JSON file into an array in c# so I can later split it up into a 2d array for processing.</p>
  
  <p>The problem I was having was I could not find any examples of people doing what I was trying to do. This meant I was just editing code a little an hoping for the best.</p>
  
  <p>I have managed to get something working that will:</p>
  
  <ul>
  <li>Read the file Miss out headers and only read values into array.</li>
  <li>Place a certain amount of values on each line of an array. (So I
  could later split it an put into 2d array)</li>
  </ul>
  
  <p>This was done with the code below but it crashes the program after entering a few lines into the array. This might have to do with the file size.</p>
  
  <pre><code>// If the file extension was a jave file the following 
  // load method will be use else it will move on to the 
  // next else if statement
  if (fileExtension == ".json") 
  {
      int count = 0;
      int count2 = 0;
      int inOrOut = 0;
      int nRecords=1; 
      JsonTextReader reader = new JsonTextReader(new StreamReader(txtLoaction.Text));
      string[] rawData = new string[5];
      while (reader.Read())
      {
          if (reader.Value != null)
              if (inOrOut == 1)
              {
                  if (count == 6)
                  {
                      nRecords++;
                      Array.Resize(ref rawData, nRecords);
                      //textBox1.Text += "\r\n";
                      count = 0;
                  }
                  rawData[count2] += reader.Value + ","; //+"\r\n"
                  inOrOut = 0;
                  count++;
                  if (count2 == 500)
                  {
                      MessageBox.Show(rawData[499]);
                  }
              }
              else
              {
                  inOrOut = 1;
              }
      } 
  }
  </code></pre>
  
  <p>A snippet of the JSON I am working with is:</p>
  
  <pre><code>[ 
      { "millis": "1000", 
        "stamp": "1273010254", 
        "datetime": "2010/5/4 21:57:34", 
        "light": "333", 
        "temp": "78.32", 
        "vcc": "3.54" }, 
  ] 
  </code></pre>
  
  <p>I need the values out of this JSON.  For example, I need "3.54", but I would not want it to print the "vcc".</p>
  
  <p>I am hoping someone can show me how to read a JSON file in and only extract the data that I need and put it into an array or something that I can use to later put into an array.</p>
