Question about value type in the dotNET.System_Collections.Hashtable()?

Hi all,

In our test, we need a hashtable to store the test values. Key is string, value is array. The fDict.Add doesn't work. Does anyone know, how to use dotNET.System_Collections.Hashtable() for this case? 

var fDict =dotNET.System_Collections.Hashtable().zctor();

var val1 = ["100", "160", "200", "250", "300"];

fDict.Add("key1", val1);

Best Regards,

Jie
