传入字典的模型项是 'Web.Services.Package[]' 类型

Question

完整错误：

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'.

收到此错误。堆栈跟踪如下。有人知道吗？似乎无法让它消失。这与字典有关并传入 Web.Services.Package[]，但是 [] 是什么意思？

这是一个 Razor 页面，在 C# 中，我试图在其中编辑 "Package".

类型的对象

[]表示一个Array，表示给定类型的一系列对象。关于它在内存中的工作方式有一些细节，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，并且您可能不得不简单地传递第一个元素而不是通过 array[0] 其中 array 是报告为数组类型的变量的名称。
