首先必須先創建一個"類別庫"(新增->類別庫 in VS2012)
一定要有關鍵字[Serializable]否則無法,然後建立一個Struct
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
using System.Runtime.Serialization;
using System.Runtime.Serialization.Formatters.Binary;
using System.ComponentModel;
namespace PassingStruct
{
public class Class1
{
}
[Serializable]
public struct MemberList
{
private BindingList<Member> _MemberCollection;
public BindingList<Member> MemberCollection
{
get
{
if (this._MemberCollection == null)
this._MemberCollection = new BindingList<Member>();
return this._MemberCollection;
}
}
}
[Serializable]
public struct Member
{
public int ID { get; set; }
public int age { get; set; }
public string name { get; set; }
public int number { get; set; }
public string sex { get; set; }
}
}
編譯時會產生錯誤訊息,但其實還是成功(在Debug資料夾內)會有一個dll檔產生。
OK,到這邊,需要將dll檔加入參考到要序列化的程式碼。
以下為序列化程式碼
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.IO;
using System.Runtime.Serialization;
using System.Runtime.Serialization.Formatters.Binary;
using PassingStruct;
namespace Binary_filestreame
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
PassingStruct.MemberList list = CreateClass();
SerializeToBinary("list.dat", list);
}
public PassingStruct.MemberList CreateClass()
{
PassingStruct.MemberList list = new PassingStruct.MemberList();
list.MemberCollection.Add(new PassingStruct.Member() { ID = 1, age = 18, name = "paul walker", number = 999, sex = "male" });
list.MemberCollection.Add(new PassingStruct.Member() { ID = 2, age = 20, name = "jonathan brewster", number = 123, sex = "female" });
return list;
}
public static void SerializeToBinary(string FileName, object Object)
{
Stream stream = null;
IFormatter/*用於格式化已經序列化的東西*/ format = new BinaryFormatter();//以二進位格式序列化和還原序列化物件
try
{
stream = new FileStream(FileName,FileMode.Create,FileAccess.Write,FileShare.Read);
format.Serialize(stream, Object);
}
catch(Exception ex)
{
throw ex;
}
finally
{
stream.Close();
}
}
private void button2_Click(object sender, EventArgs e)
{
PassingStruct.MemberList list = DeserializeFromBinary<PassingStruct.MemberList>("list.dat");
}
public static T DeserializeFromBinary<T>(string FileName)
{
IFormatter formatter = new BinaryFormatter();
Stream stream = null;
try
{
stream = new FileStream(FileName, FileMode.Open, FileAccess.Read, FileShare.Read);
object obj = formatter.Deserialize(stream);
if (obj == null)
return default(T);
else
return (T)obj;
}
catch (Exception ex)
{
throw ex;
}
finally
{
stream.Close();
}
}
}
}
注意到在using這邊
using System.IO;
using System.Runtime.Serialization;
using System.Runtime.Serialization.Formatters.Binary;
using PassingStruct;//這個就是dll檔,除了在Visual Studio專案裡面選擇 專案->加入參考->瀏覽->dll檔,還要加入這一行
然後,序列化基本上就完成了。接著就是反序列化：（以下為反序列化程式碼）
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.IO;
using System.Runtime.Serialization;
using System.Runtime.Serialization.Formatters.Binary;
using PassingStruct;
namespace serialize_transfer
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
//File.wr
}
public static T DeserializeFromBinary<T>(string FilePath)
{
IFormatter formatter = new BinaryFormatter();
Stream stream = null;
try
{
stream = new FileStream(FilePath, FileMode.Open, FileAccess.Read, FileShare.Read);
object obj = formatter.Deserialize(stream);//問題出在這邊
if (obj == null)
return default(T);
else
return (T)obj;
}
catch (Exception ex)
{
throw ex;
}
finally
{
stream.Close();
}
}
private void button1_Click(object sender, EventArgs e)
{
PassingStruct.MemberList list = DeserializeFromBinary<PassingStruct.MemberList>(@"C:\Users\daniel\Dropbox\Visual Studio 2012\Projects\Binary_filestreame\Binary_filestreame\bin\Debug\list.dat");
}
}
}
同樣也需要加入參考以及+using的程式碼 記得反序列化路徑要弄對就好了。
應用的部分,可使用在DataGridView上面
BindingSource Source = new BindingSource();
public void Form1_Load(object sender, EventArgs e)
{
this.Source.DataSource = CreateClass().MemberCollection;
this.dataGridView1.DataSource = this.Source;
this.bindingNavigator1.BindingSource = this.Source;
this.textBox1.DataBindings.Add("Text", this.Source, "ID");
this.textBox2.DataBindings.Add("Text", this.Source, "name");
this.textBox3.DataBindings.Add("Text", this.Source, "age");
this.textBox4.DataBindings.Add("Text", this.Source, "phone");
this.textBox5.DataBindings.Add("Text", this.Source, "sex");
}
End
