mvc3视图检查布尔C#

[英]mvc3 View checking a boolean c#

I was wondering how I could do this Boolean check. 我想知道如何进行布尔检查。 I'm not very good with mvc3 Views... 我对mvc3视图不是很好...

Error 1 Cannot convert lambda expression to type 'bool' because it is not a delegate type 错误1无法将lambda表达式转换为类型'bool',因为它不是委托类型

@model Project.Domain.Worker //active is a value in worker  
@if (model => model.active == true) {  //this doesn't work 
        <div class="editor-label">
            @Html.LabelFor(model => model.param)
        </div>
        <div class="editor-field">
            @Html.EditorFor(model => model.param)
            @Html.ValidationMessageFor(model => model.param)
        </div>
}    

Since model.active is a boolean, you can simply do: 由于model.active是布尔值,因此您可以简单地执行以下操作:

@if (Model.active)

When dealing with boolean types, you never need to compare them to true or false . 处理布尔类型时,您无需将它们与truefalse进行比较。

Your confusion may arise from HTML helpers taking a lambda - an if cannot take a lambda. 您的困惑可能源于HTML帮助程序使用lambda- if不能使用lambda。
