<select multiple @Bind> in pure .razor page

is possible @Bind the selected multiple values with some internal variable?
normally the select @Bind an internal string variable, but how do same thing with multiple selected row? there are some solution without the .cshtml, @model implementation and using?

because if I try to use an array like IList the runtime give me an error like:
System.InvalidOperationException: The type 'System.Collections.Generic.IList`1[[System.String, System.Private.CoreLib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e]]' does not have an associated TypeConverter that supports conversion from a string. Apply 'TypeConverterAttribute' to the type to register a converter.

@niconico49 thanks for contacting us.

That is not a currently supported scenario I believe.

@SteveSandersonMS We might be able to support this through element.selectedOptions?

@javiercn Yes, we certainly could implement some support for this. I think it's reasonable for this to be a backlog item currently.

I think this is a duplicate of #5519
