问题
这个错误是因为你的 Settings+Save 结构体没有被标记为可序列化。要解决这个问题，你需要在 Settings+Save 结构体前面加上 [System.Serializable] 属性，就像你在 Settings 类前面所做的一样。这将告诉系统可以对这个结构体进行序列化操作。修改后的代码如下：
[System.Serializable]
public struct Save
{
public int save_point;
public int percent;
}
这样修改后，你的 Save 结构体就可以被正确序列化，不再会出现这个错误。

I try to save progress with code but I have problems with it. I try 5 ways but It always gives an error.Thanks.
I have trouble with this code:
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
[System.Serializable]
public class Settings
{
public enum Languages
{
English,
Turkce
}
public struct Save
{
public int save_point;
public int percent;
}
public Languages lang;
public Save save1;
public Save save2;
public Save save3;
public static Settings data = new Settings();
}
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
using System.IO;
using System.Runtime.Serialization.Formatters.Binary;
public class Settings_Issues : MonoBehaviour
{
public bool _out;
public int _out_type;
public int _out_id;
void Start()
{
if(_out)
{
if (_out_type == 0)
{
if (_out_id == 0) GetComponent<Text>().text = "%" + Settings.data.save1.percent.ToString();
if (_out_id == 1) GetComponent<Text>().text = "%" + Settings.data.save2.percent.ToString();
if (_out_id == 2) GetComponent<Text>().text = "%" + Settings.data.save3.percent.ToString();
}
}
}
void Update()
{
}
public static void Load()
{
string path = Application.persistentDataPath + "/Save.gsd";
BinaryFormatter formatter = new BinaryFormatter();
FileStream stream = new FileStream(path, FileMode.Open);
Settings data = formatter.Deserialize(stream) as Settings;
stream.Close();
Settings.data= data;
}
public static void Save()
{
BinaryFormatter formatter = new BinaryFormatter();
string path = Application.persistentDataPath + "/Save.gsd";
FileStream stream = new FileStream(path, FileMode.Open);
formatter.Serialize(stream, Settings.data);
stream.Close();
Debug.Log(Application.persistentDataPath + "/Save.gsd");
}
}
It gives this error when I use Save() with a button:
SerializationException: Type 'Settings+Save' in Assembly 'Assembly-CSharp, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null' is not marked as serializable.
The full error is :

Settings类被标记为可序列化，但嵌套结构Save没有被标记为可序列化。为了能够序列化Settings，也需要将Save标记为可序列化。例如：
[System.Serializable]
public struct Save
{
public int save_point;
public int percent;
}
英文:
Your Settings class is marked as serializable, but the nested struct Save isn't. To be able to serialize Settings, Save also needs to be marked as serializable. i.e:
[System.Serializable]
public struct Save
{
public int save_point;
public int percent;
}
