Question

C# 中的类型“System.Windows.Forms.DataGridViewr”未标记为可序列化 问题

namespace ClientTest
{
[Serializable]
public class b_datagridview : DataGridView
{
public b_datagridview()
{
}
public byte[] ObjectToByte()
{

IFormatter formatter = new BinaryFormatter();
MemoryStream ms = new MemoryStream();
byte[] b;
formatter.Serialize(ms, this);
ms.Position = 0;
b = new byte[ms.Length];
ms.Read(b, 0, b.Length);
ms.Close();
return b;
}
}
}以上为我的代码. 我已经添加了[Serializable],为什么还不可以?!

Answer 1

你要序列化什么？b_datagridview吗？还是datagridview的datasource？
这里有问题： formatter.Serialize(ms, this);
我之前写过的一个给初学者学习的序列化和反序列话的demo 希望对你有帮助
[Serializable]
public class MyObject
{
public int n1 = 0;
public int n2 = 0;
public String str = null;
}

public class test
{
public static void Main()
{
Serialzable();
DisSerialzable();
}

private static void Serialzable()
{
MyObject obj = new MyObject();
obj.n1 = 1;
obj.n2 = 24;
obj.str = "Some String";
IFormatter formatter = new BinaryFormatter();
Stream stream = new FileStream("MyFile.bin", FileMode.Create, FileAccess.Write, FileShare.None);
formatter.Serialize(stream, obj);
stream.Close();
}
private static void DisSerialzable()
{
IFormatter formatter = new BinaryFormatter();
Stream stream = new FileStream("MyFile.bin", FileMode.Open, FileAccess.Read, FileShare.Read);
MyObject obj = (MyObject)formatter.Deserialize(stream);
stream.Close();

// Here's the proof.
Console.WriteLine("n1: {0}", obj.n1);
Console.WriteLine("n2: {0}", obj.n2);
Console.WriteLine("str: {0}", obj.str);
}
}

追问

我发现只要是windowform下的控件,都无法序列化,,,最后我自己写了一个column的属性类,再讲这个类序列化,这个到时解决了这个问题.不知道我的控件无法直接序列化结论是否正确.
