Question

VBA (and I assume VB) has a Variant type which I believe takes up more memory, but covers various data types.

Is there an equivalent in c# ?

In a windows form say I had the following, how would I amend the type of z so that it runs ok

    private void uxConvertButton_Click(object sender, EventArgs e)
    {
        int x = 10;

        byte j = (byte)x;
        upDateRTB(j);

        long q = (long)x;
        upDateRTB(q);

        string m = x.ToString();
        upDateRTB(m);
    }

    void upDateRTB(long z) {
        MessageBox.Show(this,"amount; "+z);
    }

Answer 1

void upDateRTB(object z) {
    MessageBox.Show(this, "amount; " + Convert.ToString(z));
}
