Ambiguous match?

[cesaryuan]

new EvalContext().Execute(@"""test"".IndexOf('e', 1);");

Hi, the above sentence throws error like below. But it works in VS. Could you check it? Thank you!

Z.Expressions.Compiler.Shared.EvalException

Hello @cesaryuan ,

Thank you, we will look at it.

This is probably causing because we also support single quote to be a string like this abc and not only a character.

We will look at how we could improve the logic.

Best Regards,

Jon

Hello @cesaryuan ,

The v4.0.31 is finally released.

We improved our code to better handle Ambiguous matches for multiple scenarios such as this one.

Let me know if everything is now working correctly with this scenario.

Best Regards,

Jon

@JonathanMagnan Thank you so much! But I update to the v4.0.31 and it still throw the same errors.

static void Main(string[] args)
{
    new EvalContext().Execute(@"""test"".IndexOf('e', 1);");
}

No problem, we will look at it again.

Hello @cesaryuan ,

The v4.0.32 has been released.

Could you try this one and let us know if everything is working correctly this time?

Best Regards,

Jon

[cesaryuan]

@JonathanMagnan It seems fixed. Thank you!
