尝试 BindingSource.AddNew方法 [ ^ ]。

已解决 - 我发现另一个线程有一个类似的问题。当您添加bindingNavigator时，Visual Studio将自行添加一些代码。通常，当用户单击bindingNavigatorAddItem按钮时，除了您添加的任何代码之外，还会触发此代码，从而为您提供越界记录索引。在InitializeComponent过程中，我找到并禁用该行



Me.BindingNavigator1.AddNewItem = Me.BindingNavigatorAddNewItem



这样做解决了我的问题。

Solved - I found another thread with a similar problem. When you add the bindingNavigator Visual Studio will add some code on its own. Normally, when a user clicks the bindingNavigatorAddItem button this code is fired in addition to any code you add giving you an out-of-bounds record index. In the InitializeComponent procedure I located and disabled the line

Me.BindingNavigator1.AddNewItem = Me.BindingNavigatorAddNewItem

Doing so resolved my problem.
