问题描述

我需要从 Razor 视图中检查我的模型是否有效.如果它有效，那么我希望能够显示一些 HTML.

I need to do a check if my model is valid from inside my Razor view. If it's valid then I want to be able to show some HTML.

我该怎么做.我想要像

@if ( Model.IsValid ) {

}

但是上面的方法不起作用

but the above does not work

推荐答案

您可以检查 ModelState 是否有效，但请记住，您只检查 Web 请求发出时 ModelState 的有效性制作:

You can check whether or not the ModelState is valid, but keep in mind that you're only checking the validity of the ModelState at the time the web request was made:

@if (ViewData.ModelState.IsValid) {
    ...
}

此外，您可以在视图中检查模型上的属性的有效性:

Additionally, you can check validatity of a property on the model in the view:

@if (ViewData.ModelState.IsValidField("FIELD_NAME")) {
    ...
}
