如何使用razor引擎（c＃mvc）简化此代码..有没有办法在剃刀引擎中混合使用c＃和css？

实际上我在尝试这个时没有得到正确答案

 @model FoodViewModel

@foreach (FoodView item in Model.Foodviews)
{         
 @if (item.vote == 1)
       {
        <input type="radio" name="example" class="rating" value="1"  checked="checked" />
        <input type="radio" name="example" class="rating" value="2" />
        <input type="radio" name="example" class="rating" value="3" />
        <input type="radio" name="example" class="rating" value="4" />
        <input type="radio" name="example" class="rating" value="5" />
       } 
        else if(item.vote == 2)
       {
        <input type="radio" name="example" class="rating" value="1" />
        <input type="radio" name="example" class="rating" value="2"  checked="checked"  />
        <input type="radio" name="example" class="rating" value="3" />
        <input type="radio" name="example" class="rating" value="4" />
        <input type="radio" name="example" class="rating" value="5" />
       }
       else if (@item.vote == 3)
       {
        <input type="radio" name="example" class="rating" value="1" />
        <input type="radio" name="example" class="rating" value="2" />
        <input type="radio" name="example" class="rating" value="3" checked="checked" />
        <input type="radio" name="example" class="rating" value="4" />
        <input type="radio" name="example" class="rating" value="5" />
       } 

       else
       {
        <input type="radio" name="example" class="rating" value="1" />
        <input type="radio" name="example" class="rating" value="2" />
        <input type="radio" name="example" class="rating" value="3" />
        <input type="radio" name="example" class="rating" value="4" />
        <input type="radio" name="example" class="rating" value="5"  />
       } 
}

Answer 1

为什么不通过尝试以下方式来干掉你的代码：

for (int i = 1; i <= 5; i++)
{
     <input type="radio" name="example" class="rating" value="@i" 
     @if(i == item.vote)
     {
       checked="checked"
     }
     />
}

大概你想要某种标签/价值吗？

Answer 2

你可以尝试一个简单的循环吗？

@for (var i = 1; i < 6; i++) {
    if (i == item.vote) {
        <input type="radio" name="example" class="rating" value="@i" checked>
    } else {
        <input type="radio" name="example" class="rating" value="@i">
    }
}

或者，甚至更好，使用html助手;

@for (var i = 1; i < 6; i++) {
     @Html.RadioButton("example", i, item.vote == i, new { @class = "rating" })
}

在cz中用c＃mvc混合css
