datagrid数据源绑定winform和wpf的区别

SqlDataAdapter sda = new SqlDataAdapter();
sda.SelectCommand = cmd;
DataSet ds = new DataSet();
sda.Fill(ds);
DataGrid1.ItemsSource = ds.Tables[0];  (这是winform中的写法)

SqlDataAdapter sda = new SqlDataAdapter();
sda.SelectCommand = cmd;
DataSet ds = new DataSet();
sda.Fill(ds);
DataGrid1.ItemsSource = ds.Tables[0].DefaultView;(这是wpf中的写法)
