Hashtable writing Web Services

record

[WebMethod (Description = "aaa")]
public string aaa (Hashtable ht)
{

}

Compilation appears: The type System.Collections.Hashtable is not supported because it implements IDictionary.

Is there any way for everyone

Instead of Hashtable, use serializable objects

What I said upstairs is correct, webservice parameter types must be serializable, such as int, string, dataset, etc.

Yes, in fact, such transmission is problematic, you don’t use Hashtable as parameters
But you can use binary serialization, a netizen asked you the same question just now

If you use hashtable as the return value in java
How to call c#? Has anyone encountered it?
