Answer 1

In the sql duety, take in params SqlParameter[] like so:

public void WriteStoredProcedure( string Query, params SqlParameter[] SqlParameters ) {
    // do it
}

For cases where you're defining a parameter and want to run it in one go, you can also define it like so:

SqlParameter storedParam = new SqlParameter("@ip",SqlDbType.Varchar,40) {
    Value = "192.168.1.1"
};

Answer 2

the 'writetostoredpro' method would need to take a collection of SqlParameter objects, and then inside the method, you would need to iterate over the collection adding them to the SqlCommand.Parameters property. Take a look at this link : http://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqlcommand.parameters.aspx of how to use the propertied, and SqlCommand class for an idea of what to do: http://msdn.microsoft.com/en-us/library/z4956bkc.aspx
