C# 传入字典的模型项的类型为'；Web.Services.Package[]和#x27；

完全错误：

The model item passed into the dictionary is of type 'Web.Services.Package[]', but this dictionary requires a model item of type 'Web.Services.Package'.

获取此错误。堆栈跟踪在下面。有人知道吗？似乎无法让它消失。这与一本字典和传入

Web.Services.Package[]

有关，但是

[]

是什么意思呢

这是一个用C#编写的Razor页面，我试图编辑“Package”类型的对象

谢谢你的帮助

[]

表示，表示给定类型的一系列对象。关于如何在内存中工作，有一些细节，但这些细节仅用于将其与其他集合类型区分开来

---

在这种情况下，您需要弄清楚为什么要尝试传递多个包，您可能只需通过

array[0]传递第一个元素即可

其中

array

是作为数组类型报告的变量的名称。

错误告诉您传递数组与传递字符串的过程中到底出了什么问题

'Web.Services.Package[]

与

'Web.Services.Package'

在传递集合时，视图需要单个对象
