从类中删除必需的属性，但MVC3仍然不会在文本框中没有值的情况下发布表单

问题描述

我上课.曾经，我已经使用System.ComponentModel ...将类的属性设置为[Required].

I have a class. At one point, I had set the properties of the class to [Required] using System.ComponentModel....

好的，然后我意识到这是不需要的.我已经删除了必需的属性，但是当我尝试将表单提交给ActionResult时，表单没有发布，并且仍在尝试强制填充TextBoxFor(theModelProperty).

Okay, then I realized this was not needed. I have removed the required property but when I try to submit the form to an ActionResult the form does NOT post and still is trying to enforce the TextBoxFor(theModelProperty) to be populated.

我已经删除了"obj"文件夹，"bin"文件夹，并且还清理了"解决方案.仍然没有分辨率.

I have deleted the "obj" folder, the "bin" folder, and also "Cleaned" the solutions. Still NO resolution.

我不想做一个愚蠢的解决方法，我想正确地做事.知道为什么会这样吗?

I don't want to do a stupid workaround, I would like to do things correctly. Any idea why this occurs?
