I get huge data of object type as input via a collection.
I’m trying to form a query by joining these items with comma.

Inside the select query I do some actions like null check, etc.

This works fine in English. However, when run in French/Spanish due to comma as DecimalSeparator I get values with comma’s instead of dot.

Without parsing for double, float, decimal types any other option to make it CultureInvariant?

Sample program:

    var dict = new Dictionary<int, object>()
    {
        { 1, "abc" },
        { 2, "def" },
        { 3, 33 },
        { 4, 44 },
        { 5, 5.5 },
        { 6, 6.6 }
    };
    return string.Join(",", dict.Values.Select(x => x));

In English returns:
abc,def,33,44,5.5,6.6

Whereas in Spanish:
abc,def,33,44,5,5,6,6

How do I get the same result as English irrespective of culture without parsing for each specific type?
