Please find the BoundAccountsofMember method code behind .
请找到后面的 BoundAccountsofMember 方法代码。
private void BoundAccountsOfMember()
{
Dictionary<Int16, AccountType> accountTypes = SessionController.CurrentMember.GetAccountTypes();
ddlWithdrawFrom.Items.Clear();
foreach (AccountType accountType in accountTypes.Values)
{
ddlWithdrawFrom.Items.Add(new ListItem(accountType.AccountName, accountType.AccountId.ToString()));
}
ListItem li = ddlWithdrawFrom.Items.FindByValue(SessionController.DefaultAccountId.ToString());
if (li != null)
{
ddlWithdrawFrom.SelectedIndex = -1;
li.Selected = true;
}
}
The above exception is being thrown from Page_Load event. Regards Srividhya
上述异常是从 Page_Load 事件抛出的。问候斯里维提亚

I could guess that you have a problem with a session here. You're checking SessionController.CurrentMember != nullin Page_Load, but not in your BoundAccountsOfMember.
我猜你在这里的会话有问题。你检查SessionController.CurrentMember != null的Page_Load，但不是在你的BoundAccountsOfMember。
I believe that is a problem here if you're saying it happens time to time. You probably should work on session renewal/invalidation in your modules to make sure your code will not run without a valid session.
如果你说它不时发生，我相信这是一个问题。您可能应该在模块中处理会话更新/失效，以确保您的代码在没有有效会话的情况下不会运行。
