Generic Data Set

I need to make general class for transform Tuple data, to Data Set. Is possible to call "unknown data method's" with different return type. For example <Tuple<List<string,int>>, <Tuple<List<int,int>> and put it in like generic type?

I have a generic Class

static class Helper<T>
{
    public static DataSet Transform(T data)
    {
        ...transform logic
        return new DataSet();
    }
}

And another class, which call diferent methods, which return diferents types.

For example i call method which return this type: Tuple<List<Tuple<long, string, string>>, List<Tuple<long, string, string>>> and i try to call geneeric class method Transform and insert specific date type, which i get from method result by GetType(). But i have problem with it.

For Example - this work, i set string like generic type and string content.

Helper<string>.Transform("test");

But if i want to use "unknown" type, i don't know, how i put it like date type.

var data = Data.GetData();
var type = data.GetType();
//this doesn't work
Helper<type>.Transform(data);

I hope so my question is clear.

Thanks for your help.
