C# System.InvalidCastException:对象不能存储在此类型的数组中。在C中

当使用setter为下面提到的对象赋值时，我得到了下面的错误。这是我的密码

mmultiInfoValues2.AttributeValue.SetValueString[]数组，0；：。请帮忙

变量是字符串数组的数组。您试图将其中一个数组的值设置为字符串数组数组，而不是单个字符串数组，这是无效的。从语法上讲，你可以做：

mmultiInfoValues2.AttributeValues = array;

---

但如果不知道设置AttributeValue的具体用途，就不清楚这是否能实现您想要的效果。也许您需要将数组从array复制到mmultiInfoValues2，而不仅仅是更改引用。

嘿，我认为AttributeValues只是一个二维字符串变量。请参见->公共字符串[][]属性值{get；set；}好吧，这是一个数组数组，与二维数组有些不同，但是您试图将一个应该是字符串数组的值设置为另一个锯齿数组，这就是为什么会出现错误的原因。如果您可以将其减少为。目前很难说问题出在哪里。
