          Button btn = new Button();
          btn.Name = DataTable.Rows[i]["Name"].ToString();
          btn.Text = DataTable.Rows[i]["PostCode"].ToString();

       String First_Button_Name = ........... 

Answer 1

如果要获取要添加到FlowLayoutPanel的第一个按钮的名称，无论这些按钮如何到达那里，请使用：

 string firstButtonName = flowlayoutpanel.Controls.OfType<Button>().FirstOrDefault()?.Name;

Answer 2

This is the value you are searching for:

DataTable.Rows[0]["Name"].ToString()

but make sure you have at least an element before you try to get this value.
