发生无效的强制转换异常

看起来像DtMfgDate是某种日期控件，并且可能期望有效日期分配给它的值.

试试这个:

Looks like DtMfgDate is some sort of date control and would probably expect a valid date value assigned to it.

Try this:

DtMfgDate.Value = Date.Parse(VaccineLedgerView.SelectedItems(0).SubItems(2).Text)

您需要执行一些额外的编码，以确保解析的值实际上是有效日期.您也许可以考虑使用TryParse函数.

祝你好运！

You need to do some extra coding to make sure that the value parsed is actually a valid date. You maybe could look into the TryParse function for that.

Good luck!

尝试..

try..

DtMfgDate.Value = Convert.ToDateTime(VaccineLedgerView.SelectedItems(0).SubItems(2).Text).ToString("dd-MMM-yyyy");
