Dictionary type supports .?

[zhenlei520]

If I introduce a value of type Dictionary<string,string>, I can use . in Expression to get the value of the specified key.

For example:
My rule engine type is

{
     public Dictionary<string, string> Dimensions { get; set; }
}

where the value of Dimensions is

{"name":"tony"}

According to my understanding Expression should be

metadata.Dimensions.Any(d=>d.Key=="snakeTest" && d.Value=="tony")

However, during actual use, I found that it is also feasible to write as follows
metadata.Dimensions.name == "tony"

Why is this happening? Does RulesEngine do any special processing?

you need to register IEnumerable so that Any can work

Thanks for your reply. I'm just curious about why you can use . directly when the data type is Dictionary. For example, if the parameter of type Dictionary<string, string> is metadata, and the value of the key is name, you can get the corresponding value through metadata.name. This is inconsistent with C# syntax.

(Any)[https://learn.microsoft.com/en-us/dotnet/api/system.linq.enumerable.any?view=net-8.0] needs to be registered to be used. similar to a custom function

You misunderstood what I meant. I didn't want to know how to use the Any method, but why metadata.name can be used to get the value of the key name in the array.
