我有以下课程

namespace TaxiResults.Model
{

public class SearchResult
{
    public string status { get; set; }
    public SearchResultResult result { get; set; }
}

public class SearchResultResult
{
    public SearchResultOffer offer { get; set; }
}

public class SearchResultOffer
{
    public SearchResultOffer1[] offers { get; set; }
}

public class SearchResultOffer1
{
    public SearchResultAddress[] addresses { get; set; }
    public string chnl { get; set; }
    public string companyInfoId { get; set; }
    public string companyName { get; set; }
    public string bookingId { get; set; }
    public string tz { get; set; }
    public string pickupDateTime { get; set; }
    public string pickupDateTimeUTC { get; set; }
    public int routeDuration { get; set; }
    public int routeDistance { get; set; }
    public SearchResultPricedetail priceDetail { get; set; }
    public float tax { get; set; }
    public string services { get; set; }
    public int bagCount { get; set; }
    public int passengerCount { get; set; }
    public int productType { get; set; }
    public string resultset { get; set; }
    public string companyInfoId3cd { get; set; }
}

public class SearchResultPricedetail
{
    public SearchResultOriginalprice originalPrice { get; set; }
    public SearchResultFinalprice finalPrice { get; set; }
}

public class SearchResultOriginalprice
{
    public SearchResultAmount[] amounts { get; set; }
}

public class SearchResultAmount
{
    public string currency { get; set; }
    public string priceExcludingTax { get; set; }
    public float priceExcludingTaxNumber { get; set; }
    public string priceTotal { get; set; }
    public float priceTotalNumber { get; set; }
    public float exchangeRate { get; set; }
    public string priceTax { get; set; }
    public float priceTaxNumber { get; set; }
}

public class SearchResultFinalprice
{
    public SearchResultAmount1[] amounts { get; set; }
}

public class SearchResultAmount1
{
    public string currency { get; set; }
    public string priceExcludingTax { get; set; }
    public float priceExcludingTaxNumber { get; set; }
    public double priceTotal { get; set; }
    public float priceTotalNumber { get; set; }
    public float exchangeRate { get; set; }
    public string priceTax { get; set; }
    public float priceTaxNumber { get; set; }
}

public class SearchResultAddress
{
    public SearchResultLocation location { get; set; }
    public string address { get; set; }
    public int type { get; set; }
}

public class SearchResultLocation
{
    public float lat { get; set; }
    public float lng { get; set; }
}

}

我想做一个 foreach 循环，Taxi.Model.SearchResult将它输入到我在 MVC 视图中返回的模型中。

但我得到了错误：

foreach 语句无法对“Taxi.Model.SearchResult”类型的变量进行操作，因为“Taxi.Model.SearchResult”不包含“GetEnumerator”的公共定义

我是 c#.net 的新手，谁能告诉我我需要做什么才能让我做一个 foreach 吗？

谢谢

最简单的方法就是枚举offers属性，如下所示：

SearchResultOffer searchResults = ...
foreach(var result in searchResults.offers)
{
    ...
}

但是为了能够枚举SearchResultOffer自身，您必须实现IEnumerable接口：

public class SearchResultOffer : IEnumerable<SearchResultOffer1>
{
    public SearchResultOffer1[] offers { get; set; }

    // Generic version for IEnumerable<T>
    public IEnumerator<SearchResultOffer1> GetEnumerator() 
    {
        return offers.Cast<SearchResultOffer1>().GetEnumerator();
    }

    // Non-generic version for IEnumerable
    IEnumerator IEnumerable.GetEnumerator()
    {
        return this.GetEnumerator(); // calls the generic version
    }
}

然后你可以这样做：

SearchResultOffer searchResults = ...
foreach(var result in searchResults)
{
    ...
}

查看您提供的代码，看起来SearchResult该类实际上是底层实体的单个实例，而不是这样的集合。您可能需要声明 aList<SearchResult>来存储所有结果，然后foreach在该列表中使用。

您应该实施IEnumerable<T>或IEnumerable支持 foreach。
