Question

I have a requirement to check, if datatable is null, then copy the row to datatable otherwise need to append the row to the datatable.
In this code in "else" section it should be appending a row, but here it adding a row without any values in it.In the first column it is appending a text as [System.Data.DataRow].

What I have tried:

C#

if (dtTable == null)
    {
        dtTable = (from DataRow dr in dtDetails.Rows
                   where dr["ID"].ToString() == Id
                   select dr).CopyToDataTable();
    }
    else
    {
       

        dtTable.Rows.Add(from DataRow dr in dtDetails.Rows
        where dr["ID"].ToString() == Id
        select dr)
        // Here in DataTable it adding a new row but without any values.
        // In the first column it is appending a text as [System.Data.DataRow].

    }

By looking at the code, the below code is returning a collections (1 or more)

C#

from DataRow dr in dtDetails.Rows
        where dr["ID"].ToString() == Id
        select dr

The best altrernative, I think is to loop through the object and import the row into the dtTable object.

C#

var misteryObject = from DataRow dr in dtDetails.Rows
        where dr["ID"].ToString() == Id
        select dr;

foreach (DataRow dr in misteryObject )
		   {
			 dtTable.ImportRow(dr);
		   }
