On My DataLayer , I have this code

================= DL ===================
 public DataSet FetchEmailDetails(OrgDetails userSettings)
 {
      //some code goes here          
 }

Now suppose from my .aspx page I want to acess this code

C#

=============  .aspx.cs ==============
//create object of BL
OrgDetails org = new OrgDetails();
//passing this object in DL 
DataSet dSetEmailDetails = FetchEmailDetails(org);

Now I want functionality like this

C#

public DataSet FetchEmailDetails(This_could_be_any_class_from_BL bl)
{
     //some code goes here

}

So that I can reuse that method on any page

This is only going to be possible if there is some common function that you can put on all your potential BL classes, but you solve this with interface

C#

public interface IDetailsRepository
{
    DataSet GetData();
}

public class OrgDetails : IDetailsRepository
{

    public DataSet GetData()
    {
        // code here
        return new DataSet();
    }
}

public class XyzDetails : IDetailsRepository
{

    public DataSet GetData()
    {
        // code here
        return new DataSet();
    }
}

Function;

C#

public DataSet FetchEmailDetails(IDetailsRepository bl)
{
    DataSet ds = bl.GetData();
    return ds;
}

Usage;

FetchEmailDetails(new OrgDetails());
FetchEmailDetails(new XyzDetails());

Use generic method to fulfil your requirement. Try with below code:

C#

static DataSet FetchEmailDetails<t>(T value)
{
	// This generic method returns a List with ten elements initialized.
	// ... It uses a type parameter.
	// ... It uses the "open type" T.
	
	T tempObj = value;
	// Implement your logic to return DataSet
	
	DataSet ds = new DataSet();
	return ds;
}

//create object of BL
OrgDetails org = new OrgDetails();
//passing this object in DL 
DataSet dSetEmailDetails = FetchEmailDetails<orgdetails>(org);

NewClass org1 = new NewClass();
DataSet dSetEmailDetails = FetchEmailDetails<NewClass>(org1);
