Question

我不得不改变一个单选按钮以包含一个新值。要做到这一点，我必须将一个字典放在IDictionary中。密钥对于IDictionary非常有用，但是字典int和字符串根本没有拉入。我相信这是我的前端代码。任何人都可以看到我做错了什么，并举例说明如何解决？

控制器中的操作参数

IDictionary<String, Dictionary<int, String>>

查看

<fieldset>
<legend class="sr-only">Actions</legend>
<input type="hidden" name="customerId" value="@account.CustomerId" />
<input type="hidden" name="yearSetupId" value="@account.YearId" />
<label class="radio-inline"><input type="radio" name="accountActions[@(account.CustomerId)].Key[@(account.Id)].Value" value="" checked="checked">Do nothing</label>
@{
     var possibleActions = account.Balance < 0 ? new[] { 
     BalanceAdjustmentType.Zeroed, BalanceAdjustmentType.Issued }
                                    : new[] { BalanceAdjustmentType.Under, BalanceAdjustmentType.Sent };
                                }
@foreach (var action in possibleActions)
                                {
<label class="radio-inline"><input type="radio" name="accountActions[@(account.CustomerId)].Key[@(account.YearId)].Value" value="@action.BalanceId">@action.Text</label>
                                }
</fieldset>

我实际上并不了解你的控制器参数意味着什么。但我认为＆＃34; accountActions＆＃34;在您的视图中是您的＆＃34;控制器参数＆＃34;的变量。如果是这样，那么您可以通过accountActions [Key] [InnerKey]访问嵌套的dict值。

<fieldset>
    <legend class="sr-only">Actions</legend>
    <input type="hidden" name="customerId" value="@account.CustomerId" />
    <input type="hidden" name="yearSetupId" value="@account.YearId" />
    <label class="radio-inline">
        <input type="radio" name="@accountActions[account.CustomerId][account.Id]" value="" checked="checked">
        Do nothing
    </label>    

    @{ 
        var possibleActions = account.Balance < 0 
        ? new[] { BalanceAdjustmentType.Zeroed, BalanceAdjustmentType.Issued } 
        : new[] { BalanceAdjustmentType.Under, BalanceAdjustmentType.Sent }; 
    } 

    @foreach (var action in possibleActions) { 
        <label class="radio-inline">
            <input type="radio" name="@accountActions[account.CustomerId][account.YearId]" value="@action.BalanceId">
            @action.Text
        </label>
    }
</fieldset>
