在 C# 字符串中转换 json 对象

Question

我有这个

[
    {"type":"knife","knifeNO":"1","knifeName":"Shadow Daggers | Crimson Web","knifeEx":"Field Tested","knifeFv":" 0.3297","price":"42 keys","inspect":"steam://rungame/730/76561202255233023/+csgo_econ_action_preview%20S76561198041444572A6024013354D17188164719027219402"},

]

.json 文件（对象的 json 数组），我想为文件提取值对（如 type:"knife"）并将它们设为 C# 字符串，以便我可以在我正在处理的一个项目中使用它们！但我无法让它工作，我尝试了很多东西！

有人可以帮我吗？

由于您正在处理具有不同属性的多个不同类别的对象（即枪和刀），您可以考虑将它们序列化为 dynamic 对象并通过 JSON.NET 公开的 DeserializeObject<T>() 方法以这种方式使用它们：

using Newtonsoft.Json;

// Example of your JSON Input
var input = "{your-huge-array-here}";   
// Serialized weapons
var weapons = JsonConvert.DeserializeObject<dynamic[]>(input);
// Go through each type as expected
foreach(dynamic gun in weapons.Where(w => w.type == "gun"))
{
    Console.WriteLine("Gun Number: {0}, Gun Name: {1}",gun.gunNo,gun.gunName);
}
foreach(dynamic knife in weapons.Where(w => w.type == "knife"))
{
    Console.WriteLine("Knife Number: {0}, Knife Name: {1}",knife.knifeNO,knife.knifeName);
}

根据您的需要，您可以更改 foreach 循环的内容以实际填充字符串、构建您自己的自定义类等。
