Use ExecuteScalar

https://msdn.microsoft.com/en-gb/library/system.data.sqlclient.sqlcommand.executescalar(v=vs.110).aspx[^]

C#

command.Parameters.AddWithValue("@Location", Location);
string c = (string) command.ExecuteScalar();

If it "doesn't work" check the "Location" variable has what you expect, or try surrounding the names in your SQL with square brackets as Currency is probably a reserved word

SqlCommand command = new SqlCommand("SELECT [Currency] FROM [Currency] WHERE Country = @Location", con2);
