如何将 StringContent() 类型转换为类型的对象<MyModelClass>在 C# 中使用 Visual Studio 2019

Question

I'm trying to turn the string result below in the first line of code into an object of type "Root.cs". I have "Root.cs" class set up in my Visual Studio 2019 "solution" with proper classes set up to turn the string result into the object.

This line of code works fine to get me the string I need:

var result = client.PostAsync(endpoint, payload).Result.Content.ReadAsStringAsync().Result;

Here's the contents of the string "result":

    {"sections":[{"id":"Building_Configuration","name":"Building_Configuration","sections":[{"id":"B    uilding_Configuration.Parameters_SP","name":"Building_Configuration.Parameters_SP","sectio      ns":[],"variables":[{"id":"Building_Configuration.Parameters_SP.fixtureStrategy_SP","name":"Bui lding_Configuration.Parameters_SP.fixtureStrategy_SP","valueType":"String","distinctValueCou    nt":3.0,"allowMultipleAssignments":false,"values":[{"name":"ETA","value":"ETA","properties":[{  "id":"fullyqualifiedname","value":"ETA","type":"String"},{"id":"name","value":"ETA","type":"Stri    ng"}],"type":"SingletonValue","assigned":"byDefault","incompatible":false},{"name":"ETD","valu  e":"ETD","properties":[{"id":"fullyqualifiedname","value":"ETD","type":"String"},{"id":"name","v    alue":"ETD","type":"String"}],"type":"SingletonValue","incompatible":false},{"name":"ETA/ETD",  "value":"ETA/ETD","properties":[{"id":"fullyqualifiedname","value":"ETA/ETD","type":"String"},{ "id":"name","value":"ETA/ETD","type":"String"}],"type":"SingletonValue","incompatible":false}],"

Now, I need to create the object of type "Root" (My Model Class) for the purpose of picking and choosing certain values out of it. Shouldn't this line work for that?

Root MyObject = JsonConvert.DeserializeObject<Root>(result);

Here's the definition of Root.cs:

My "result" and my "Root.cs" class are each larger than the 30,000 characters limit here. So, I've had to only post a portion of my string "result" and my "Root.cs" class. I'm trying to simplify this question. Please forgive me while I learn how to use this...

Answer 1

Answer: I was making the newbie mistake of trying to return a string that I picked out of a "Root.cs" Model class as a Root object. I had the return type of the method set to Root instead of string. Upon changing the return type to string, that part of my solution works fine.

It works fine like this:

public string CreateExecPost(FormData person2){

            var payload = new StringContent(newPost, Encoding.UTF8, "application/json");
        
        var result = client.PostAsync(endpoint, payload).Result.Content.ReadAsStringAsync().Result;//result is already in JSON

        Root MyObject = JsonConvert.DeserializeObject<Root>(result);

        //return MyObject.language; //WORKS
        return MyObject.language;
 }
