json - 搜索 json 项

Question

所以我正在尝试使用 defindex 搜索我的 json 文件中的项目并返回项目名称，但是我得到一个错误。我进行了搜索，但似乎没有什么相关的。

            var json = File.ReadAllText(dota2schemaFilePath);
            var dota2schema = JsonConvert.DeserializeObject<schema>(json);

            foreach (Item item in Items)     //ERROR HERE
            {
                if (item.Defindex == 4793)
                    itemname = item.Name;

错误 2 非静态字段、方法或属性“schemaexample.schema.Items.get”需要对象引用

它似乎需要一个参考。我如何简单地搜索项目？

这是我的完整代码：

            foreach (Item item in Items)     //ERROR HERE

                    itemname = item.Name;
            }
            Console.WriteLine(itemname);

            Console.WriteLine("Press any key to exit");
            Console.ReadKey();


        }

        protected class schemaresult
        {
            public schema result { get; set; }
        }

    }
}

Answer 1

我能够使用本机 JavaScriptSerializer 对您的 JSON 文件进行搜索。

我将结果对象更改为

public class schemaresult
{
    public schema result { get; set; }
}

public class schema
{
    public Item[] Items { get; set; }
    public string ItemsGameUrl { get; set; }
    public int Status { get; set; }
}

public class Item
{
    public string Name { get; set; }
    public int Defindex { get; set; }
    public string ItemClass { get; set; }
    public string ItemTypeName { get; set; }
    public string ItemName { get; set; }
    public bool ProperName { get; set; }
    public int ItemQuality { get; set; }
    public string ImageInventory { get; set; }
    public int MinIlevel { get; set; }
    public int MaxIlevel { get; set; }
    public string ImageUrl { get; set; }
    public string ImageUrlLarge { get; set; }
    public string ItemDescription { get; set; }
    public Attribute[] Attributes { get; set; }
    public string ItemSet { get; set; }
}
public class Attribute {
    public string name { get; set; }
    public string @class { get; set; }
    public string value { get; set; }
}

并将转换代码更改为

var json = File.ReadAllText(dota2schemaFilePath);
        System.Web.Script.Serialization.JavaScriptSerializer serializer = new System.Web.Script.Serialization.JavaScriptSerializer();
        serializer.MaxJsonLength = Int32.MaxValue;
        var schema_result = serializer.Deserialize<schemaresult>(json);

        foreach (Item item in schema_result.result.Items )      
        {
            if (item.Defindex == 4793)
            {
                itemname = item.Name;
                break;
            }
        };
