    "  function displayImage(elem) {" +
    "    var image = document.getElementById(\"canvas\");" +
    "    image.src = elem.value;        " +
    "  }" +
    "  </script>" +
    "</head>" +
    "<body>" +
    "  <form name=\"controls\">" +
    "    <img id=\"canvas\" src=\"pictures/fire1.jpg\" />" +
    "    <select name=\"imageList\" onchange=\"displayImage(this);\">" +
    "      <option value=\"pictures/001JRPchargeable.png\">Fire 1</option>" +
    "      <option value=\"pictures/001JRPNonchargeable.png\">Fire 2</option>" +
"</select>" +
"  </form>" +
"</body>" +
"</html>";

Solution

You can use this code:

string saveHtml = "<html>" +
    "<head>" +
    "  <title>Select Image</title>" +
    "  <script type=\"text/javascript\">" +
    "  function displayImage(elem) {" +
    "    var image = document.getElementById(\"canvas\");" +
    "    image.src = elem.value;        " +
    "  }" +
    "  </script>" +
    "</head>" +
    "<body>" +
    "  <form name=\"controls\">" +
    "    <img id=\"canvas\" src=\"pictures/fire1.jpg\" />" +
    "    <select name=\"imageList\" onchange=\"displayImage(this);\">" +
    "      <option value=\"pictures/001JRPchargeable.png\">Fire 1</option>" +
    "      <option value=\"pictures/001JRPNonchargeable.png\">Fire 2</option>" +
"</select>" +
"  </form>" +
"</body>" +
"</html>";


string path = @"D:\Test.html";
System.IO.File.WriteAllText(path, saveHtml)
