我的部分代码将机器的文件路径以以下格式序列化为JSON。我正在努力使用此JSON并将文件路径重新放回原处。我正在使用Newtonsoft JSON库;我发现它非常适合构建JSON。如您所见,我的JSON具有嵌套对象。
我有的JSON:
{
".": {
"proc": {
"15": {
"task": {
"15": {
"exe": {},
"mounts": {
"list_of_files": [
"mounts.xml"
]
},
"mountinfo": {
"list_of_files": [
"mountinfo.xml"
]
},
"clear_refs": {
"list_of_files": [
"clear_ref.xml"
]
}
}
}
},
"14": {
"loginuid": {
"list_of_files": [
"loginuid.xml"
]
},
"sessionid": {
"list_of_files": [
"sessionid.xml"
]
},
"coredump_filter": {
"list_of_files": [
"coredump_filter.xml"
]
},
"io": {
"list_of_files": [
"io.xml"
]
}
}
}
}
}
我要从中生成的数组。
string[] dirArray = {
"./proc/15/task/15/exe",
"./proc/15/task/15/mounts/mounts.xml",
"./proc/15/task/15/mountinfo/mountinfo.xml",
"./proc/15/task/15/clear_refs/clear_ref.xml",
"./proc/14/loginuid/loginuid.xml",
"./proc/14/sessionid/sessionid.xml",
"./proc/14/coredump_filter/coredump_filter.xml",
"./proc/14/io/io.xml"
}
到目前为止,我的工作-我将JSON反序列化为动态变量,但不确定如何处理两个问题:
编辑
对不起,我原来的JSON格式是错误的,所以它不会与工作答案由user12864提供。我收到一个错误:Unable to cast object of type 'Newtonsoft.Json.Linq.JArray' to type 'Newtonsoft.Json.Linq.JObject'.
这是一个小提琴,显示了我到目前为止所处的位置。
@ user12864的答案是正确的,但是需要对代码进行调整,以说明每个目录可以具有文件数组而不是单个“文件”对象的事实(您本来应该在问题中最初提到过) 。这是处理此问题的更新方法:
private static void AddToFileList(JObject jo, List<string> list, string prefix)
{
foreach (var kvp in jo)
{
if (kvp.Key == "list_of_files")
{
foreach (string name in (JArray)kvp.Value)
{
list.Add(prefix + name);
}
}
else
{
JObject dir = (JObject)kvp.Value;
if (dir.Count == 0)
{
list.Add(prefix + kvp.Key);
}
else
{
AddToFileList(dir, list, prefix + kvp.Key + "/");
}
}
}
}
完整演示:
using System;
using System.Collections.Generic;
using Newtonsoft.Json;
using Newtonsoft.Json.Linq;
class Program
{
static void Main(string[] args)
{
string json = @"
{
""."": {
""proc"": {
""15"": {
""task"": {
""15"": {
""exe"": {},
""mounts"": {
""list_of_files"": [
""mounts.xml""
]
},
""mountinfo"": {
""list_of_files"": [
""mountinfo.xml""
]
},
""clear_refs"": {
""list_of_files"": [
""clear_ref.xml""
]
}
}
}
},
""14"": {
""loginuid"": {
""list_of_files"": [
""loginuid.xml""
]
},
""sessionid"": {
""list_of_files"": [
""sessionid.xml""
]
},
""coredump_filter"": {
""list_of_files"": [
""coredump_filter.xml""
]
},
""io"": {
""list_of_files"": [
""io.xml""
]
}
}
}
}
}";
JObject jo = JObject.Parse(json);
foreach (string path in CreateFileList(jo))
{
Console.WriteLine(path);
}
}
private static List<string> CreateFileList(JObject jo)
{
List<string> ret = new List<string>();
AddToFileList(jo, ret, "");
return ret;
}
private static void AddToFileList(JObject jo, List<string> list, string prefix)
{
foreach (var kvp in jo)
{
if (kvp.Key == "list_of_files")
{
foreach (string name in (JArray)kvp.Value)
{
list.Add(prefix + name);
}
}
else
{
JObject dir = (JObject)kvp.Value;
if (dir.Count == 0)
{
list.Add(prefix + kvp.Key);
}
else
{
AddToFileList(dir, list, prefix + kvp.Key + "/");
}
}
}
}
}
输出:
./proc/15/task/15/exe
./proc/15/task/15/mounts/mounts.xml
./proc/15/task/15/mountinfo/mountinfo.xml
./proc/15/task/15/clear_refs/clear_ref.xml
./proc/14/loginuid/loginuid.xml
./proc/14/sessionid/sessionid.xml
./proc/14/coredump_filter/coredump_filter.xml
./proc/14/io/io.xml
