C# 根据.net中的条件从DTO类对象中筛选或删除数组对象

我有一个API，它以以下格式给出响应：

[
    {
        "OrderId" : "Order1"
        "filterOrder": [
            "ABC",
            "XYZ"
        ],
        "Details": [
            {
                "id": 1
                "value": 100,                
                "filterDetails": [
                    "Apples",
                    "Oranges"
                ]                
            },
            {
                "id": 2
                "value": 200,                
                "filterDetails": [
                    "Banana",
                    "Blank"
                ]                
            }
        ]   
        
    },
    {
        "OrderId" : "Order2"
        "filterOrder": [
            "PQR",
            "Blank"
        ],
        "Details": [
            {
                "id": 1
                "value": 100,                
                "filterDetails": [
                    "Apples",
                    "Peaches"
                ]                
            },
            {
                "id": 2
                "value": 200,                
                "filterDetails": [
                    "Banana",
                    "Mango"
                ]                
            },
        ]   
        
    }
]

我收到响应并将其反序列化为一个模型类（与上面的结构相同）。
我的要求是从响应中删除所有这些对象，其中过滤器被称为“空白”。
在上面的示例中，输出应该如下所示：

[
    {
        "OrderId" : "Order1"
        "filterOrder": [
            "ABC",
            "XYZ"
        ],
        "Details": [
            {
                "id": 1
                "value": 100,                
                "filterDetails": [
                    "Apples",
                    "Oranges"
                ]                
            }
        ]   
        
    }
]

在网上搜索后，我尝试了几个例子，但无法继续

var item = responseObject.Find(x=>x.filterOrder == "Blank");
responseObject.Remove(item);

但这会导致编译错误。有谁能帮我按要求过滤数据吗。非常感谢。至少有两种方法

如果您知道只有一个项目将包含空白，请使用以下命令：

List<Order> rootobject = JsonConvert.DeserializeObject<List<Order>>(jsonStr);
var itemToRemove = rootobject.Find(x => x.filterOrder.Contains("Blank"));
rootobject.Remove(itemToRemove);

您的JSON示例包含错误（缺少逗号） 我分为两步（不知道是否需要从孩子身上删除空格）

FilterOrder是一个数组，但您正在将其与字符串进行比较。。。那不行。如果要检查数组中是否有要查找的项，请使用“包含”

rootobject.RemoveAll(x => x.filterOrder.Contains("Blank"));

//or 
rootobject = rootobject.Where(x => !x.filterOrder.Contains("Blank")).ToList();

void Main()
{
    string i = "[{\"OrderId\":\"Order1\",\"filterOrder\": [ \"ABC\", \"XYZ\" ], \"Details\": [ { \"id\": 1, \"value\": 100, \"filterDetails\": [ \"Apples\", \"Oranges\" ] }, { \"id\": 2, \"value\": 200, \"filterDetails\": [ \"Banana\", \"Blank\" ] } ] }, { \"OrderId\": \"Order2\", \"filterOrder\": [ \"PQR\", \"Blank\" ], \"Details\": [ { \"id\": 1, \"value\": 100, \"filterDetails\": [\"Apples\", \"Peaches\" ]}, { \"id\": 2, \"value\": 200, \"filterDetails\": [\"Banana\",\"Mango\"]}]}]";
    var lst = JsonConvert.DeserializeObject<List<Root>>(i);

    //first level
    lst.Where(w => w.filterOrder.Contains("Blank"))
    .ToList().ForEach(fe => {lst.Remove(fe);});
        
    //details level
    lst.ToList().ForEach(fe =>
    {
        fe.Details.Where(ww=> ww.filterDetails.Any(a => a.Contains("Blank")))
            .ToList().ForEach(details =>
            { 
                fe.Details.Remove(details);
            });
    });
            
    lst.Dump();
    
}

    public class Detail
{
    public int id { get; set; }
    public int value { get; set; }
    public List<string> filterDetails { get; set; }
    
    public Detail(){
        filterDetails = new List<string>();
    }
}

public class Root
{
    public string OrderId { get; set; }
    public List<string> filterOrder { get; set; }
    public List<Detail> Details { get; set; }
    
    public Root(){
        Details = new List<Detail>();
        filterOrder = new List<string>();
    }
}

lst.RemoveAll(x => x.filterOrder.Contains("Blank"));
    lst.ForEach(fe => {fe.Details.RemoveAll(r=> r.filterDetails.Contains("Blank"));});
