如何解决

public DataSet ConvertArraylistToDataSet(ArrayList arrayList)
        {
            dsEntityReturned = new DataSet();
            dtEntityReturned = new DataTable();
            dsEntityReturned.Tables.Add(dtEntityReturned);

            dsEntityReturned.Tables[0].Columns.Add("NAME", System.Type.GetType("System.Object"));
        
            foreach (object  obj  in arrayList)
            {
                    DataRow rows = dsEntityReturned.Tables[0].NewRow();
                    rows[0] =obj; // here the error blows up
                    dsEntityReturned.Tables[0].Rows.Add(rows);
                    //return dsEntityReturned;  
            }
           // return null;              
 }

Hope this[^] might help you.

为此，您需要先将arraylist记录传输到临时DataTable，然后使用DataSet来保存该DataTable.

然后将DataSet设置为DataGridView的DataSource属性，并将DataTable设置为DataMember属性.

For this purpose you need to first transfer arraylist records to a temporary DataTable then use a DataSet to hold that DataTable.

Then put DataSet to DataSource property and DataTable to DataMember property of your DataGridView.
