The difference between model and model in ASP. NET Mvc4

@model Model Definition

Use the @model keyword to define a model in an action (which can often be called an entity Class),

In fact, the dynamic variable is instantiated, so that the "Model" variable can be called directly in the cshtml file .

An instance of this model needs to be transmitted through a controller , and if not, "model" will be null.

A model can be an entity class or a list instance, and a Dictionary object can be defined, but

The instance in the Controller must be the same as the one returned by the action, otherwise an error will occur.
