Asp.net 有人可以在.net中使用json数组吗？

我正在尝试将我的应用程序与MercadolibreAPI集成。我可以毫无问题地列出一个新项目，但当我尝试插入图片数组时，集成不起作用。 错误消息：

{"message":"body.invalid_field_types","error":"[invalid property type: [pictures] expected List but was null value: [pictures:[[source:http://www.nichepursuits.com/wp-content/uploads/2014/02/buy-websites.jpg], [source:http://thumb9.shutterstock.com/display_pic_with_logo/639229/176602316/stock-vector-best-buy-rubber-stamp-red-icon-isolated-on-white-background-vector-illustration-176602316.jpg]]]]","status":400,"cause":[]}

当我尝试使用下面的第二个选项时，VisualStudio显示了一个编译错误

我已经测试了很多声明，但都失败了

暂定1:

IRestResponse r = m.Post("/items", ps, new
                {
                    title = _item.title,
                    category_id = _item.category_id,
                    price = _item.price,
                    currency_id = _item.currency_id,
                    available_quantity = _item.available_quantity,
                    buying_mode = _item.buying_mode,
                    listing_type_id = _item.listing_type_id,
                    condition = _item.condition,
                    description = _item.description,
                    warranty = _item.warranty,
                    pictures = new {pictures = new [] 
                    {
                        new {source = "http://www.nichepursuits.com/wp-content/uploads/2014/02/buy-websites.jpg"}, 
                        new {source = "http://thumb9.shutterstock.com/display_pic_with_logo/639229/176602316/stock-vector-best-buy-rubber-stamp-red-icon-isolated-on-white-background-vector-illustration-176602316.jpg"}
                    }}
                });

暂定2:

IRestResponse r = m.Post("/items", ps, new
            {
                title = _item.title,
                category_id = _item.category_id,
                price = _item.price,
                currency_id = _item.currency_id,
                available_quantity = _item.available_quantity,
                buying_mode = _item.buying_mode,
                listing_type_id = _item.listing_type_id,
                condition = _item.condition,
                description = _item.description,
                warranty = _item.warranty,
                pictures = [{"Source":"Value"},{"Source":Value2}]

            });

 pictures = new {pictures = new [] 
                {
                    new {source = "http://www.nichepursuits.com/wp-content/uploads/2014/02/buy-websites.jpg"}, 
                    new {source = "http://thumb9.shutterstock.com/display_pic_with_logo/639229/176602316/stock-vector-best-buy-rubber-stamp-red-icon-isolated-on-white-background-vector-illustration-176602316.jpg"}
                }}

pictures = new[] 
{
    new { source = "http://www.nichepursuits.com/wp-content/uploads/2014/02/buy-websites.jpg" },
    new { source = "http://thumb9.shutterstock.com/display_pic_with_logo/639229/176602316/stock-vector-best-buy-rubber-stamp-red-icon-isolated-on-white-background-vector-illustration-176602316.jpg"}
}

C#对JSON数组一无所知，幸运的是，它有自己的数组

您的代码：

IRestResponse r = m.Post("/items", ps, new
            {
                title = _item.title,
                category_id = _item.category_id,
                price = _item.price,
                currency_id = _item.currency_id,
                available_quantity = _item.available_quantity,
                buying_mode = _item.buying_mode,
                listing_type_id = _item.listing_type_id,
                condition = _item.condition,
                description = _item.description,
                warranty = _item.warranty,
                pictures = [{"Source":"Value"},{"Source":Value2}]

            });

 pictures = new {pictures = new [] 
                {
                    new {source = "http://www.nichepursuits.com/wp-content/uploads/2014/02/buy-websites.jpg"}, 
                    new {source = "http://thumb9.shutterstock.com/display_pic_with_logo/639229/176602316/stock-vector-best-buy-rubber-stamp-red-icon-isolated-on-white-background-vector-illustration-176602316.jpg"}
                }}

pictures = new[] 
{
    new { source = "http://www.nichepursuits.com/wp-content/uploads/2014/02/buy-websites.jpg" },
    new { source = "http://thumb9.shutterstock.com/display_pic_with_logo/639229/176602316/stock-vector-best-buy-rubber-stamp-red-icon-isolated-on-white-background-vector-illustration-176602316.jpg"}
}

这实际上不是数组，而是匿名对象。 尝试重写它：

IRestResponse r = m.Post("/items", ps, new
            {
                title = _item.title,
                category_id = _item.category_id,
                price = _item.price,
                currency_id = _item.currency_id,
                available_quantity = _item.available_quantity,
                buying_mode = _item.buying_mode,
                listing_type_id = _item.listing_type_id,
                condition = _item.condition,
                description = _item.description,
                warranty = _item.warranty,
                pictures = [{"Source":"Value"},{"Source":Value2}]

            });

 pictures = new {pictures = new [] 
                {
                    new {source = "http://www.nichepursuits.com/wp-content/uploads/2014/02/buy-websites.jpg"}, 
                    new {source = "http://thumb9.shutterstock.com/display_pic_with_logo/639229/176602316/stock-vector-best-buy-rubber-stamp-red-icon-isolated-on-white-background-vector-illustration-176602316.jpg"}
                }}

pictures = new[] 
{
    new { source = "http://www.nichepursuits.com/wp-content/uploads/2014/02/buy-websites.jpg" },
    new { source = "http://thumb9.shutterstock.com/display_pic_with_logo/639229/176602316/stock-vector-best-buy-rubber-stamp-red-icon-isolated-on-white-background-vector-illustration-176602316.jpg"}
}

甚至只是字符串数组：

pictures = new string[] 
{
    "http://www.nichepursuits.com/wp-content/uploads/2014/02/buy-websites.jpg",
    "http://thumb9.shutterstock.com/display_pic_with_logo/639229/176602316/stock-vector-best-buy-rubber-stamp-red-icon-isolated-on-white-background-vector-illustration-176602316.jpg"
}

第二种选择：

---

pictures=[{“Source”：“Value”}，{“Source”：Value2}]

不是一个有效的行，不允许您用C#写这个。

描述“不工作”。你有错误吗？它怎么不能实现你想要的？嗨，梅森。我已经编辑了这个主题。谢谢。你说它现在抛出一个编译错误，但是你需要解释编译错误是什么。在第一个代码块上，

pictures

加倍：

pictures=new{pictures=new[].

。请尝试一下

pictures=new[].

谢谢。解决方法如下。
