我知道以前有人问过这个问题，但似乎没有任何补救措施是我的解决方案。

我有一个aspx页面和一个带有Page_Load例程的代码。我的例程将记录写入 SQL 表以捕获用户的凭据。

Page_Load 有一个!IsPostBack检查，aspx 有AutoEventWireup="True"，我没有img或任何其他元素会导致AutoPostback我知道。仍然Page_Load被调用两次。

这是我的.aspx页面和背后的代码。我希望有人可以提供帮助。

    if (!IsPostBack)

        SqlConnection conn = new SqlConnection(Sitecore.Configuration.Settings.GetConnectionString("feedback"));
        SqlCommand cmd = new SqlCommand("Insert_fb", conn);
        cmd.CommandType = CommandType.StoredProcedure;
