Question

我有一个push类属性的方法到NameValuCollection

private NameValueCollection ObjectToCollection(object objects)
{

    NameValueCollection parameter = new NameValueCollection();


    Type type = objects.GetType();

    PropertyInfo[] properties = type.GetProperties(BindingFlags.Instance |
                                                    BindingFlags.DeclaredOnly |
                                                    BindingFlags.Public);
    foreach (PropertyInfo property in properties)
    {
        if (property.GetValue(objects, null) == null)
        {
            parameter.Add(property.Name.ToString(), "");
        }
        else
        {
            if (property.GetValue(objects, null).ToString() != "removeProp")
            {
                parameter.Add(property.Name.ToString(), property.GetValue(objects, null).ToString());
            }
        }
    }

    return parameter;
    }

在我的情况下，当我将My Model类传递给此方法时，它是正确的，但是在我的Model类中，我使用另一个这样的模型

public class Brand
{
    public MetaTags MetaTag { get; set; } // <---- Problem is here

    public string BrandName { get; set; }

}

public class MetaTags
{
    public string Title { get; set; }

    public string Description { get; set; }

    public string Language { get; set; }
}

它不会将MetaTags类属性添加到集合中，只需将MetaTag添加到集合

我希望此方法返回此OutPut

key:Title       Value:value
key:Description Value:value
key:Language    Value:value
key:BrandName   Value:value

但是此方法会返回此

key:MetaTag     Value:
key:BrandName   Value:value

我怎么能这样做？非常感谢你的帮助

在添加空字符串之前，请检查当前属性是否为MetaTags。如果是这样，请递归使用此函数。

private NameValueCollection ObjectToCollection(object objects)
{

NameValueCollection parameter = new NameValueCollection();


Type type = objects.GetType();

PropertyInfo[] properties = type.GetProperties(BindingFlags.Instance |
                                                BindingFlags.DeclaredOnly |
                                                BindingFlags.Public);
foreach (PropertyInfo property in properties)
{
    if (property.PropertyType == typeof(MetaTags))
    {
            parameter.Add(property.Name.ToString(),ObjectToCollection(property.GetValue(objects, null)))
    }
    else{
    if (property.GetValue(objects, null) == null)
    {
        parameter.Add(property.Name.ToString(), "");
    }
    else
    {
        if (property.GetValue(objects, null).ToString() != "removeProp")
        {
            parameter.Add(property.Name.ToString(), property.GetValue(objects, null).ToString());
        }
    }
    }
}

return parameter;
}
