Question

I’m writing a custom javascript converter and I’m receiving a string that should contain an int.
This is what I’m doing:

public class MyObjectToJson : JavaScriptConverter
{
public override object Deserialize(IDictionary<string, object> dictionary, Type type, JavaScriptSerializer serializer)
{

  MyObject TheObject = new MyObject; 

  if (serializer.ConvertToType<int>(dictionary["TheInt"]) == true)
  {
    MyObject.TheInt = serializer.ConvertToType<int>(dictionary["TheInt"]);
  }

However, it’s not working on the conditional statement. What do I need to change? I want to test that I’m getting an int.

Thanks.

Change your code to use this condition:

 int value;
 if (int.TryParse(serializer.ConvertToType<string>(dictionary["TheInt"]), out value)
 {
    MyObject.TheInt = value;
 }

This is a better solution than relying on an exception to be thrown, as catching exceptions is computationally expensive.
