Can i make the No of fields in a GetObject Method any no of items
I have in my c# application a need to write into a postgresql database
I use a simple GetObject method shown below
[code]private void WriteRecord()
{
var p = GetObject(LocationIDValue.Text, LocDescriptionValue.Text, LoginDetails.staticcompany, Convert.ToInt32(idValue.Text), LoginDetails.staticinsertupdatedeletetag);
NewDataAccess.WriteData("public.splocationcode_updateinsert", p);
}[/code]
It takes fields value from the screen passes them to GetObject method to define
parameters before using these to write in to my postgresql database
The GetObject Method is shown below
[]public static object GetObject(string parameter01, string parameter02, string parameter03, int parameter04, string parameter05)
{
return new
{
locationidx = parameter01,
locdescriptionx = parameter02,
companycodex = parameter03,
idx = parameter04,
dowhatx = parameter05
};
}[/code]
The applications works fine for this Table with 5 fields
The problem i now have is if i have to address writing to another table with fields more or less than 5 fields.
Do I have to provide a GetObject method with the no of parameters equal to the no of fields in that Table.. If Yes will i have to do this for every table in my application ??
Is there a way to make the no of items in the GetObject method have any no of fields.
I was thinking of checking the GetObject Method into a library and then pass the no of fields as string and the parameters as a Datatable
I just dont know if my thinking is right or if there is another way to achieve the same goal of using the GetObject method to address 2 tables with different no of fields
I will be grateful for any suggestion.

Thanks for your comment. I really needed an expert to help review and ventilate my thoughts. .. I actually use Dapper in this project but I am not sure if that will affect my solution.
What is the Purpose ??
In my C# project each time i have to write , read or delete from the database I have a statement like
GlobalConfig.Connection.GetTaxGroupRates();
(There each statement above goes to execute a method )
For a project with about 100 Tables that means having equivalent of these statement written about 300 times (ie read, write and delete x No of Table)
I then came across the method below that allow me read from my postgresql database without using GlobalCofig......
[]public static List<T> ReadData<T>(string sql, object p)
{
var output = new List<T>(); // If you want to return an empty list instead, use this
using (var conn = new NpgsqlConnection(LoginDetails.staticconnectionstring))
{
output = conn.Query<T>(sql, p, commandType: CommandType.StoredProcedure).ToList();
}
return output;
}[/code]
That mean if I am able to specify my stored procedure (called sql) and the parameters ( called p) i can just within my user interface do my read with the method above.
So the purpose was to reduce avoid repeating
Globalconfig.........
Is there any other way i can achieve my Goal
Thanks

Thanks for pointing me in the right direction
I will try to read up using Dapper to specify the parameters
If I do not succeed I will request a Dapper specialist to help
look at my syntax issues.
Once again Thanks

This looks terribly dynamic. This is not the way to go with ,NET and a RDBMS as both systems are strongly typed. Someone mentioned Dapper, which I don't know. Maybe there it is the concept. But it really sounds wrong.
Last but not least: A custom method in a normal program can be never called GetObject. Get is reserved for explicit getter methods. And object is an internal name. What is the purpose of it`? This should be part of the name.
