我怎样才能做到这一点。我想是这样

How can I do this. I want something like

@if ( Model.IsValid ) {

}

但上面不工作

推荐答案

您可以检查ModelState中是否有效，但请记住，你只检查ModelState中的有效性当时的Web请求是制作：

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，你可以检查属性validatity在视图模型：

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

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