or you can try, if it comes as "1" when it's true then simply comapre:



With Command.Parameters
            .Add("Search", SqlDbType.Bit).Value = RDPrivacy.SelectedItem.Value = "1"
        End With

I have a situation where I am generating dynamic conditions to check like

string condition="100 < 125"

how can I convert it to boolean as I have to check the condition and depending on the result I have to move ahead. How to do when I try

Convert.ToBoolean(condition).toString()
It gives error. Please let me know the solution.
