You can use Jint. It can parse and execute JavaScript. We are interested in parsing, so we can do:
static void Main(string[] args)
{
try
{
var validCode = "alert('Hello World!');";
var invalidCode = "alert['Hello World!');";
var jsParser = new JavaScriptParser();
var result = jsParser.Parse(validCode);
result = jsParser.Parse(invalidCode); //Will throw...
}
catch (Exception ex)
{
//Invalid input!!
}
}
