Retrieving keys and values from a .NET hashtable as strings

I came across a snippet of code written in MATLAB invoking an .NET assembly, creating an instance of a class and then access methods of the class using that object. One of the methods returns a .NET hashtable. I want to know if there is a way to convert the keys and values of this .NET hashtable to usable data types in MATLAB. I have so far been unable to find any documentation or online help to do this.

ht = 

  Hashtable with properties:

        IsReadOnly: 0
       IsFixedSize: 0
    IsSynchronized: 0
              Keys: [1×1 System.Collections.Hashtable+KeyCollection]
            Values: [1×1 System.Collections.Hashtable+ValueCollection]
          SyncRoot: [1×1 System.Object]
             Count: 1

What would be the right way to extract the information in this .NET hashtable object? Ideally, I would want the values as strings.
