c#向类发送对象

本文关键字：对象 | 更新日期: 2023-09-27 18:04:53

我正在编写一个既序列化又反序列化对象的类。我希望能够将这个类用于我传递给它的任何对象。

如何将对象传递给类?我需要能够访问我正在发送它的实例的类字段，并且我还需要访问类的定义，以便将文本反序列化回对象。

。

//mainpage.cs code
private void sendObjectToSerialize()
{
    var db = new DatabaseHandler();
    var myCar = new Car();
    myCar.Make = "Chevy";
    string ObjectString = db.SerializeObject(myCar);
}
private void SendStringToBeDeserialized()
{
    String myString = "SomeSerializeString" //this string would have been serialized using above Obect myCar
    var db = new DatabaseHandler();
    var myCar = new Car();
    var myCar = db.DeserializeStringToObject(String,myCar);
}
//Database Handler Code
public string SerializeObject(Object myObject)
{
    var myNewObject = new myObject();//doesn't work - error myObject used as a variable not a type
    //...serialize the object passed to this function
}
public Object DeserializeStringToObject(String ObjectString ,Object myObject)
{
    var myNewObject = new myObject;//error myObject used as a variable not a type
    //convert string to Object of type myObject...
    return mynewObject;
}

c#向类发送对象

下面是我的序列化器类代码:

// serializer.cs
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Runtime.Serialization.Json;
using System.Text;
using System.Threading.Tasks;
namespace QMC1.Handlers
{
    public class Serializer
    {

返回一个字符串，可以保存到数据库或文件中。目前，它似乎只适用于单个对象，而不是ObservableCollection<Object> 

public String ConvertObjectToJSONString<myObjectType>(myObjectType myObject)
{
    string content = String.Empty;
    var js = new DataContractJsonSerializer(typeof(myObjectType));
    var ms = new MemoryStream();
    js.WriteObject(ms, myObject);
    ms.Position = 0;
    var reader = new StreamReader(ms);
    content = reader.ReadToEnd();
    return content;
}

这将接受用上述代码创建的字符串，并再次将其作为功能齐全的Object返回给调用者。它只会转换回原始对象类型。目前，它似乎只适用于单个对象，而不是ObservableCollection<Object>。

        public myObjectType ConvertStringToObject<myObjectType>(string CarObjectString, string myObjectName)
        {
            myObjectType myObject = (myObjectType)Activator.CreateInstance(Type.GetType(myObjectName));
            var js = new DataContractJsonSerializer(typeof(myObjectType));    
            byte[] byteArray = Encoding.UTF8.GetBytes(CarObjectString);
            var ms = new MemoryStream(byteArray);
            myObject = (myObjectType)js.ReadObject(ms);    
            return myObject;  
        }
    }
}

从任何文件调用代码-以汽车模型为例。(本例中车型参数不重要)

Serializer ser = new Serializer();

将Object转换为JSON字符串

myCarString = ser.ConvertObjectToJSONString<Car>(myCar).ToString();

将字符串保存到数据库或文件。

从数据库或文件中拉出您的字符串并将其值分配给myCarString。将字符串转换为对象。

myCar = ser.ConvertStringToObject<Car>(myCarString, "NameSpace.Car");

使用新对象
