我在VS 2013中创建的WindowsForms应用程序中的DataGridView有问题.
应用程序在Debug版本中正常运行,但是当我切换到Release版本时,尝试单击datagridview单元时,我有一个例外：

Exception:Thrown: “Index -1 does not have a value.” (System.IndexOutOfRangeException)
A System.IndexOutOfRangeException was thrown: “Index -1 does not have a value.”

这是完成工作的代码：

private void dgvList_CellContentClick(object sender, DataGridViewCellEventArgs e)
{
    dgvList.Refresh();
    var senderGrid = (DataGridView)sender;

    if (e.RowIndex >= 0)
    {
        if (senderGrid.Columns[e.ColumnIndex].Name == "Delete")
        {
            Book b = (Book)dgvList.CurrentCell.OwningRow.DataBoundItem;
            ArrayOfBooks.Remove(b);
            fillGV();
        }
    }
}

private void dgvList_CellDoubleClick(object sender, DataGridViewCellEventArgs e)
{
    dgvList.Refresh();
    var senderGrid = (DataGridView)sender;
    if (senderGrid.Columns[e.ColumnIndex].Name == "Author" && e.RowIndex >= 0)
    {
        Book b = (Book)dgvList.CurrentCell.OwningRow.DataBoundItem;
        frmAuthors frmAuth = new frmAuthors(b);
        frmAuth.mainForm = this;
        frmAuth.Show();
    }
}

在该应用程序中,我还有第二种形式的代码非常相似,而且效果很好.
我找到了类似问题的答案(here),但对我没有帮助.

[编辑]

我意识到在两种构建模式下都会发生此异常,但是要发生此异常需要特定的情况.不久,我的程序将存储有关书籍的数据(保存在xml文件中),现在在创建列表并添加第一个元素时发生异常(然后在尝试单击DGV时发生),但是当我保存XMl和然后再次阅读它,我可以毫无例外地对其进行操作.

解决方法:

尝试使用BindingList(of T)而不是List(of T),并将其用作DataGridView的数据源.为了在Linq中使用,您每次都必须使用“ .ToList()”方法将其转换为列表.希望能帮助到你！
