I'm trying to map this object in C# using automapper. It is working fine but we need to map this object dynamically without using C# code, like keep this properties in Json file or database. Is there any other approach? We need to avoid code changes in C# if any new property is added or removed in any object, so we are looking to convert object1 to Object2 dynamically without code change.

I like the idea of Strongly Typed IDs and I am using it for some time. I use it also in DTOs without and major problems... till now. I have a use case where I need to generate JSON Schema from some classes which uses Strongly Type IDs like following:
[StronglyTypedId(StronglyTypedIdBackingType.Long)]
public partial struct TweetId
{
}
public class Tweet
{
public TweetId Id {get; set;}
}
So, as described, TweetID is represented as long base type.
The problem arises when I want to generate JSON Schema from this type. I am currently using Newtonsoft.Json.Schema (I also tried some others) using this code:
JSchemaGenerator generator = new JSchemaGenerator();
JSchema quotesSchema = generator.Generate(typeof(Tweet));
The result I get is:
{
"definitions": {
"Tweet": {
"type": [
"object"
],
"properties": {
"Id": {
"$ref": "#/definitions/TweetId"
}
}
},
"TweetId": {},
},
"type": "object",
"$ref": "#/definitions/Tweet"
}
But what I want is:
{
"definitions": {
"Tweet": {
"type": [
"object"
],
"properties": {
"Id": {
"type": "integer"
}
}
}
},
"type": "object",
"$ref": "#/definitions/Tweet"
}
Do you have any idea how to achive this? Newtonsoft.Json.Schema is not mendatory.
I'm using swagger codegen 3.0.21 for generating a C# api client.
The generators creates for all referenced classes additional classes in /Model beginning with AllOf[Classname].
Why does Swagger CodeGen generate these classes? What is their porpuse? They also have multiple errors with my sepcification.
Relevant changed part of the generated json:
"components": {
"schemas": {
"MyClass": {
"type": "object",
"properties": {
"id": {
"type": "integer",
"format": "int64"
},
"propertyTwo": {
"type": "integer",
"format": "int64"
},
"propertyThree": {
"allOf": [
{
"$ref": "#/components/schemas/MySecondClass"
}
],
"nullable": true
},
"propertyFour": {
"allOf": [
{
"$ref": "#/components/schemas/MyThirdClass"
}
],
"nullable": true
},
"propertyFive": {
"type": "array",
"items": {
"$ref": "#/components/schemas/MyFourthClass"
},
"nullable": true
},
"propertySix": {
"type": "boolean"
}
},
"additionalProperties": false
},
}
}
The constructor for MyClass is generated as following:
public MyClass(long? id = default(long?), long? propertyTwo = default(long?), propertyThree = default(), propertyFour = default(), List<MyThirdClass> propertyFive = default(List<MyFourthClass>), bool? propertySix = default(bool?))
As you can see the datatypes for propertyThree and propertyFour are just empty spaces.
We ran into the same issue. For generating a csharp client/models we actually use https://github.com/RicoSuter/NSwag/wiki/NSwagStudio which also provide you a lot of options and does generate the models properly
However for a client we needed a java generator as well and nswagstudio only supports csharp and typescript. I tried the suggestion of #NickSim that worked as a charm.
I have been given a REST service which provides some strange names, see json fomart below.
I have created some classes to map them to JSON using the following line:
var data = JsonConvert.DeserializeObject<SSTR)(jsond).inhoud_b.ToArray();
I have created classes such as:
Class inhoud_b {...}
Class bidt{...}
etc.
Json:
{
"nmbr": 0,
"tp": 1,
"sort": {
"sorted": false,
"unsorted": true
},
"inhoud_b":[
{
"bidt": {
"id": "144a207b-dd48-4ebe-87cb-153e3c6179c4",
"knldge": null,
"lTT": null,
"lD": {
"id": "52",
"text": "EM"
}
}
},
{
"bidt": {
"id": "155B307b-dd48-4ebe-87cb-125487856579",
"knldge": null,
"lTT": null,
"lDg": {
"id": "523",
"text": "AM"
}
}
}
],
"first": true,
"totalElements": 2
}
My question is, how can I map these entities with my own more meaningful models and use my models in my own code rather than those entities which don't make any sense to other developers?
Thank you.
You can use the JsonPropertyAttribute to annotate your model properties with their corresponding property name in the JSON - https://www.newtonsoft.com/json/help/html/JsonPropertyName.htm

Is there an easy way to convert Json string to C# object?
I have a swagger file in json format and need to make it to C# object
{
"swagger": "2.0",
"info": {
"version": "Profiles",
"title": "Profiles"
},
"paths": {
"/api/Profiles/Get": {
"get": {
"tags": [ "Profiles"],
"operationId": "Profiles_GetById",
"consumes": [],
"produces": [],
"parameters": [{ "name": "id"}]
}
},
"/api/Profiles": {
"get": {
"tags": [
"Profiles"
],
"operationId": "Profiles_GetBySubscriptionid",
"consumes": [],
"produces": [],
"parameters": [{ "name": "subscriptionId"}]
}
}
},
"definitions": {}
}
So the problem that I am facing right now is that I have no idea how to convert paths to properties of my C# object. Specifically, I have no clue how I define a C# object properties for "/api/Profiles/Get", or "/api/Profiles".
public class SwaggerObject
{
[JsonProperty("paths")]
public SwaggerPath Paths { get; set;}
}
public class SwaggerPath {
...
}
If you have a valid swagger definition, you can use AutoRest to generate a client for you. The auto-generated client includes models for all of the types you define in your swagger document.
You can then call Newtonsoft.Json.JsonConvert.DeserializeObject<MyModel>(json) after you retrieve the response. Better yet, you can you the auto generated client to make the HTTP calls in your .NET code.
Let's say this is a collection of 2 Bson documents
{
"_id": "...",
"name": "Test1",
"sub": {
"street": "134 Fake Street",
"city": "NoWhere"
}
},
{
"_id": "...",
"name": "Test2",
"sub": {
"height": "10",
"width": "20",
"sub2": {
"type": "something"
}
}
}
where the first level is a structured class but sub-levels can be completely unstructured and can have further nested documents several levels deep.
How can I deserialize this document to a C# class? All samples I have seen assume some structure in nested documents.
The following class gives an error:
public class Report
{
[BsonId]
public ObjectId _id { get; set; }
public string name { get; set; }
public BsonDocument sub { get; set; }
}
Type 'MongoDB.Bson.BsonString' with data contract name '...' is not expected. Consider using a DataContractResolver or add any types not known statically to the list of known types - for example, by using the KnownTypeAttribute attribute or by adding them to the list of known types passed to DataContractSerializer.
EDIT
What I'm trying to do might be complete non-sense. Is it a better idea to just use one BsonDocument and handle everything manually without a structured class?
I don't think the error message you are getting is from the C# driver. Can you please provide a stack trace?
I've tried to reproduce your issue but it works fine with my test program. See:
http://pastie.org/5032283
The document inserted by the above test program looks like this:
> db.test.find()
{ "_id" : ObjectId("5075fc6ee447ad1354c1f018"), "name" : "John Doe", "sub" : { "x" : 1, "y" : 2 } }
