Need help about loadstaDataFromString

Question

Hello,

If I use blazor:

I should use loadStateDataForm Stream or loadStateDataForm String?

using (var fs = File.OpenRead(stateFile))
                {
                    //_instaApi.LoadStateDataFromStream(fs);
                    _instaApi.LoadStateDataFromString(new StreamReader(fs).ReadToEnd());

                }

Based on your previous thread, I think you are using InstagramApiSharp.

We can see from its source code that LoadStateDataFromString will directly call the SerializationHelper.DeserializeFromString method, while LoadStateDataFromStream will go through some judgments and then call DeserializeFromString under certain conditions.

In view of the other possibilities preset by the author in the LoadStateDataFromStream method, and what you get now is a Stream, I recommend using LoadStateDataFromStream.

        public void LoadStateDataFromStream(Stream stream)  
        {  
            var data = SerializationHelper.DeserializeFromStream<StateData>(stream);  
            LoadStateDataFromObject(data);  
        }  
        /// <summary>  
        ///     Set state data from provided json string  
        /// </summary>  
        public void LoadStateDataFromString(string json)  
        {  
            var data = SerializationHelper.DeserializeFromString<StateData>(json);  
            LoadStateDataFromObject(data);  
        }

When I use " loadStateFromStream" ,
When I run nothing happens and just I see:
this message: Message: Loading state from file
and there is no exception.

if (File.Exists(stateFile))

            {

                message = "Loading state from file";

                using (var fs = File.OpenRead(stateFile))

                {

                    _instaApi.LoadStateDataFromStream(fs);

                }
            }
        }

When I use "_instaApi.LoadStateDataFromString"

_instaApi.LoadStateDataFromString(new StreamReader(fs).ReadToEnd());



if (File.Exists(stateFile))
            {

                message = "Loading state from file";

                using (var fs = File.OpenRead(stateFile))
                {
                   _instaApi.LoadStateDataFromString(new StreamReader(fs).ReadToEnd());

                }
            }

I encounter this exception:

ExceptionMessage: error: Newtonsoft.Json.JsonReaderException: Unexpected character encountered while parsing value: . Path '', line 1, position 1. at Newtonsoft.Json.JsonTextReader.ParseValue() at Newtonsoft.Json.JsonReader.ReadAndMoveToContent() at Newtonsoft.Json.JsonReader.ReadForType(JsonContract contract, Boolean hasConverter) at Newtonsoft.Json.Serialization.JsonSerializerInternalReader.Deserialize(JsonReader reader, Type objectType, Boolean checkAdditionalContent) at Newtonsoft.Json.JsonSerializer.DeserializeInternal(JsonReader reader, Type objectType) at Newtonsoft.Json.JsonSerializer.Deserialize(JsonReader reader, Type objectType) at Newtonsoft.Json.JsonConvert.DeserializeObject(String value, Type type, JsonSerializerSettings settings) at Newtonsoft.Json.JsonConvert.DeserializeObject[T](String value, JsonSerializerSettings settings) at InstagramApiSharp.API.InstaApi.LoadStateDataFromString(String json) at InstaSite1.Pages.Enterance.StartInstagram() in

I'm doing my project in blazor and the API recommends to
"loadStateFromString"

What is your idea?
