为什么没有序列化

[houqidian]

using System;
using System.Collections.Generic;
using System.Linq;
using System.Collections;
namespace User
{
[Serializable ]
public class UserInformation
{
private string UserName;
private string UserPassWord;

public UserInformation() { }
public UserInformation(string name, string password)
{
UserName = name;
UserPassWord = password;
}

public override string ToString()
{
return string.Format("Name:{0},PassWord:{1}", UserName, UserPassWord);
}
}

[Serializable]//使之能够序列化
public class UserCollection
{
private ArrayList UserList = new ArrayList();

public UserCollection() { }

public UserInformation GetUser(int pos)
{
return (UserInformation )UserList[pos];
}

public void AddUser(UserInformation p)
{
UserList.Add(p);
}

public void ClearUser()
{
UserList.Clear();
}

public int GetCount()
{
return UserList.Count;
}

}
}










using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
using User;
using System.Runtime.Serialization.Formatters.Binary;
using System.Runtime.Serialization ;

namespace ConsoleApplication2
{
class Program
{
static void Main(string[] args)
{
string name, password;
//UserInformation a=new UserInformation ();
UserCollection b=new UserCollection ();

FileInfo f = new FileInfo(@"D:\Test.dat");
FileStream fs = f.Create();
fs.Close();

for (int i = 0; i < 2; i++)
{
name = Console.ReadLine();
password = Console.ReadLine();
b.AddUser(new UserInformation(name, password));
}
int count = b.GetCount();
Console.WriteLine(count);
for (int j = 0; j < count; j++)
{
Console.WriteLine(b.GetUser(j));
}
SaveAsBinaryFormat(b,"Test.dat");
Console.ReadLine();
}

static void SaveAsBinaryFormat(object obj, string filename)
{
BinaryFormatter binFormat = new BinaryFormatter();

using (Stream fStream = new FileStream(filename,
FileMode.Create, FileAccess.Write, FileShare.None))
{
binFormat.Serialize(fStream, obj);
}
}
}
}


为什么test.dat文件中没有存入任何东西

[wuyq11]

MyObject obj = new MyObject();
　　IFormatter formatter = new BinaryFormatter();
　　Stream stream = new FileStream("", FileMode.Create,
　　FileAccess.Write, FileShare.None);
　　formatter.Serialize(stream, obj);
　　stream.Close();
List<T> list= new List<T>();
XmlSerializer ser = new XmlSerializer(list.GetType());
ser.Serialize(new FileStream(@"a.xml", FileMode.Create), list);

  using (Stream fStream = new FileStream(filename,
  FileMode.Create, FileAccess.Write, FileShare.None))
  {
  binFormat.Serialize(fStream, obj);
  fStream.Flush();
  fStream.Close();
  }
  }

FileInfo f = new FileInfo(@"D:\Test.dat");
SaveAsBinaryFormat(b,"Test.dat");
看看你先后写的两个文件，后一个传入的文件名是在你的程序启动路径下，不一定是D盘根目录吧。

跟踪一下就出来了。没这么复杂吧。

跟踪一下就出来了。没这么复杂吧。应该是没找到地址

学习的

[铛铛]

        ///   把对象序列化并返回相应的字节   
        public static byte[] SerializeObject(object objectToSerialize)
        {
            if (objectToSerialize == null)
                return null;
            MemoryStream memoryStream = new MemoryStream();
            BinaryFormatter binaryFormatter = new BinaryFormatter();
            binaryFormatter.Serialize(memoryStream, objectToSerialize);
            memoryStream.Position = 0;
            byte[] read = new byte[memoryStream.Length];
            memoryStream.Read(read, 0, read.Length);
            memoryStream.Close();
            return read;
        }

继续顶 已经有眉目了

[jackyzsy2008]

开始是这个文件
FileInfo f = new FileInfo(@"D:\Test.dat")

过一会儿成了这个文件
SaveAsBinaryFormat(b,"Test.dat");

你确定此文件是彼文件么？

[houqidian]

文件时出了问题 还有呢

自己顶一个 楼上的不是很懂

把ArrayList改成List<T>
