我正在使用Interop从excel表中读取多个字段，它几乎完美地工作。除了日期字段之外，每个字段都被读入，日期字段由与excel文档上的任何内容无关的奇怪数字填充。运行程序所需的代码如下所示。为了查看问题，必须运行测试类，以便查看在控制台上打印的结果以及测试类中的测试。 excel文件必须位于桌面上，标题为TEST.xlsx。如果您需要检查我的Excel工作表，则会在Google文档上链接here。

答案 0 :(得分：1)
这个奇怪的数字实际上只是以不同格式表示日期。您可以尝试在该号码上使用CDate()功能，该功能应该为您提供所需的日期。另一种选择是将其设置为明确定义为日期类型的变量。
