获取从视图模型获取财产 [英] get Get property from ViewModel

问题描述

我有推类属性的一种方法为NameValuCollection

I have one method for push class property into 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，当我通过我的模型类，这种方法它是正确的，但在我的模型类我用这样的另一种模式

in my case when I pass My Model class to this method it's for correctly,but when in my Model class I use another Model like this

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; }
}

这不是加元标记类属性的集合，只是添加元标记到集合

it's not add MetaTags Class Property to the collection and just Add MetaTag to the collection

我想这个方法返回此输出

I want this method return this OutPut

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

但这种方法返回此

but this method return this

key:MetaTag     Value:
key:BrandName   Value:value

我可怎么办呢？
对你的帮助非常感谢

how i can do it ? very thank for your help

推荐答案

添加一个空字符串之前，检查当前属性是否是元标记与否。如果是这样，递归使用此功能。

Before adding a empty string, check whether the current property is MetaTags or not. If so, use this function recursively.

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;
}
