title: splitting string error: cannot convert from string to char
body: <p>I have the following code: </p>
  
  <pre><code>textPath = Application.streamingAssetsPath + "JSONFiles/text_to_text.txt";
   StreamReader reader = new StreamReader(textPath);
   string text = reader.ReadLine();
   string[] colour = text.Split(",");
   m_textMeshPro.SetText(text);
   reader.Close();
  </code></pre>
  
  <p>The code is reading a line from txt file. I use this inside unity. But, there is a red line under the argument inside the split function (",") and when I hover over it. It says "Argument 1: cannot convert from 'string' to 'char'. </p>
