As per your question delete record from data table u used for loop thats good

so same depends upon id u can delete

int max = dt.Rows.Count - 1;

for(int i = max; i >= 0; --i)
{
         
if((int)dt.Rows[i].ItemArray[0] == someValue)
        
{
       
         dt.Rows[i].BeginEdit();
       
         dt.Rows[i].Delete();
        }
        else
     
         break;
}

dt.AcceptChanges();
