Question

使用AutoMapper和一些配置元素时遇到了一些问题。我有以下课程：

public class SocialLinkSettingConfiguration : ConfigurationSection
{
    [ConfigurationProperty("name", IsRequired = true, IsKey = true)]
    public string Name
    {
        get { return this["name"] as string; }
        set { this["name"] = value; }
    }
    [ConfigurationProperty("description", IsRequired = true)]
    public string Description
    {
        get { return this["description"] as string; }
        set { this["description"] = value; }
    }
    [ConfigurationProperty("url", IsRequired = true)]
    public string Url
    {
        get { return this["url"] as string; }
        set { this["url"] = value; }
    }
    [ConfigurationProperty("fontAwesomeClass", IsRequired = false)]
    public string FontAwesomeClass
    {
        get { return this["fontAwesomeClass"] as string; }
        set { this["fontAwesomeClass"] = value; }
    }
    [ConfigurationProperty("imageUrl", IsRequired = false)]
    public string ImageUrl
    {
        get { return this["imageUrl"] as string; }
        set { this["imageUrl"] = value; }
    }
}

public class SocialLinkSettingConfigurationCollection : ConfigurationElementCollection
{
    public SocialLinkSettingConfiguration this[int index]
    {
        get { return (SocialLinkSettingConfiguration)BaseGet(index); }
        set
        {
            if (BaseGet(index) != null)
            {
                BaseRemoveAt(index);
            }
            BaseAdd(index, value);
        }
    }
    public void Add(SocialLinkSettingConfiguration serviceConfig)
    {
        BaseAdd(serviceConfig);
    }

    public void Clear()
    {
        BaseClear();
    }

    protected override ConfigurationElement CreateNewElement()
    {
        return new SocialLinkSettingConfiguration();
    }

    protected override object GetElementKey(ConfigurationElement element)
    {
        return ((SocialLinkSettingConfiguration)element).Name;
    }

    public void Remove(SocialLinkSettingConfiguration serviceConfig)
    {
        BaseRemove(serviceConfig.Name);
    }

    public void RemoveAt(int index)
    {
        BaseRemoveAt(index);
    }

    public void Remove(string name)
    {
        BaseRemove(name);
    }
}
public class SocialLinkSetting
{
    public string Name { get; set; }
    public string Description { get; set; }
    public string Url { get; set; }
    public string FontAwesomeClass { get; set; }
    public string ImageUrl { get; set; }
}

我可以在SocialLinkSetting和SocialLinkSettingConfiguration之间创建一个映射就好了。但是，当我尝试将SocialLinkSetting列表转换为SocialLinkSettingConfigurationCollection时，我每次都会失败。

我要做的是获取社交链接列表，并将其转换为单个SocialLinkSettingConfigurationCollection对象，其中包含所有SocialLinkSetting并转换为SocialLinkSettingConfiguration。

我似乎无法做到这一点。每次，它都不知道如何将List转换为SocialLinkSettingConfigurationCollection，然后添加每个项目。

非常感谢任何帮助。

谢谢，本

您可以这样做：

Mapper.Initialize(cfg =>
        {
            cfg.CreateMap<SocialLinkSetting, SocialLinkSettingConfiguration>();
            cfg.CreateMap<List<SocialLinkSetting>, SocialLinkSettingConfigurationCollection>()
            .AfterMap((source, dest, resolutionContext) =>
                {
                    dest.Clear();
                    source.ForEach(i => dest.Add(resolutionContext.Mapper.Map<SocialLinkSettingConfiguration>(i)));
                });
        });

使用AutoMapper将List <object>映射到ConfigurationElementCollection
