Dapper üzerinde tür dönüşümü

{DapperRow, billing_currency_code = 'USD', count(*) = '6'}

If the column name genuinely is "count(*)", then you can cast the row to a dictionary:

var data = (IDictionary<string,object>)row;
object value = data["count(*)"];

For that to work (at least, in SQL Server), your query would need to be something like:

select count(*) as [count(*)]

However, in most cases the column doesn't have a name, in which case: fix your query ;p

Actually, I'd probably say fix your query anyway; the following would be much easier to work with:

select count(*) as [Count]
