How to convert appsettings.json section to dynamic and then to class object in C#
问题
我将以下部分进行翻译：
我有一个 appsettings：
"testData": [
{
"target": "MarketMirrorClient.GetContests",
"mockData": [
{
"request": {
"contestKeys": [ "testContestKey1" ]
},
"response": {
"contests": [
{
"contestKey": "testContestKey1",
"contestType": "football",
"contestStatus": "InPlay"
}
]
}
},
{
"request": {
"contestKeys": [ "testContestKey2" ]
},
"response": {
"contests": [
{
"contestKey": "testContestKey2",
"contestType": "soccer",
"contestStatus": "PreGame"
}
]
}
}
]
}
]
我将只回答你的问题，不提供额外内容。关于在哪里实现 IConvertible，你可以在 MockData 类的 Response 属性上实现 IConvertible 接口。在你的情况下，这是因为你尝试将 Response 从 Dictionary<string, object> 转换为特定类型时出现异常，所以你需要在 Response 类型上实现 IConvertible 接口以进行类型转换。
英文:
I have an appsettings:
"testData": [
{
"target": "MarketMirrorClient.GetContests",
"mockData": [
{
"request": {
"contestKeys": [ "testContestKey1" ]
},
"response": {
"contests": [
{
"contestKey": "testContestKey1",
"contestType": "football",
"contestStatus": "InPlay"
}
]
}
},
{
"request": {
"contestKeys": [ "testContestKey2" ]
},
"response": {
"contests": [
{
"contestKey": "testContestKey2",
"contestType": "soccer",
"contestStatus": "PreGame"
}
]
}
}
]
}
]
I serialize the testData.mockData.request to a Dictionary<string, object>. However, when I try to convert the retrieved object from the dictionary to a particular type, it throws an exception saying IConvertible needs to be implemented e.g.
builder.Services.Configure<MockTestData>("testData");
The models are:
public class MockTestData
{
public List<TestData> TestData { get; set; } = new();
}
public class TestData
{
public string Target { get; set; }
public List<MockData> MockData { get; set; } = new();
}
public class MockData
{
public Dictionary<string, object> Request { get; set; }
public object Response { get; set; }
}
Where should I implement the IConvertible?
I tried changing the types from object to dynamic or ExpandoObject but the error is either IConvertible needs to be implemented or Cannot convert object to 'whatever' type i am casting to i.e. List<string>

这对我有效
List<TestDatum> testData = configuration.GetSection("testData")
.Get<List<TestDatum>>();
public class TestDatum
{
public string target { get; set; }
public List<MockDatum> mockData { get; set; }
}
public class Contest
{
public string contestKey { get; set; }
public string contestType { get; set; }
public string contestStatus { get; set; }
}
public class MockDatum
{
public Request request { get; set; }
public Response response { get; set; }
}
public class Request
{
public List<string> contestKeys { get; set; }
}
public class Response
{
public List<Contest> contests { get; set; }
}
```

this works for me
List<TestDatum> testData = configuration.GetSection("testData")
.Get<List<TestDatum>>();
public class TestDatum
{
public string target { get; set; }
public List<MockDatum> mockData { get; set; }
}
public class Contest
{
public string contestKey { get; set; }
public string contestType { get; set; }
public string contestStatus { get; set; }
}
public class MockDatum
{
public Request request { get; set; }
public Response response { get; set; }
}
public class Request
{
public List<string> contestKeys { get; set; }
}
public class Response
{
public List<Contest> contests { get; set; }
}
