Sql parameter problem

Hello

I have this:

public SqlParameter GetParameter(string sqlparam)

{
SqlParameter param = cmd.Parameters.Add(sqlparam);

param.Direction = ParameterDirection.Output;

return param;

}

and I get:

Cannot implicitly convert type 'int' to 'System.Data.SqlClient.SqlParameter'

problem is that I dont "want" to be needed to specify datatype of the
parameter, if I check "6 of 6" in that yellow hint-box, as I get it, I'm
able to just pass the parameter-name.

or what's needed to do?

TIA
/Lasse

The problem is you are calling the following overload of Add

int Add( object o );

and you are trying to assign it to a SqlParameter reference - hence the error message.
if you can supply the value as well you can call this overload

SqlParameter Add(string name, object value);

OK in that case you'll need to change your code as follows:

SqlParameter GetParameter(SqlCommand cmd, string pname)
{
SqlParameter p = new SqlParameter();
p.ParameterName = pname;
p.Direction = ParameterDirection.Output;
cmd.Parameters.Add(p);
return p;
}

btw: when are you doing to set the param type for the out param?

SqlParameter defaults its SqlDbType to NVarChar. So unless you are only going to return NVarChar types and you preset the size, this isn't going to work.

Also, if you don't pass the SqlCommand in how are you going to call cmd.Parameters.Add, do you have it as a member variable?
