将WinForms按钮标记为可序列化

这是我第一个序列化的程序。

尝试序列化按钮控件时出错。

public Form1()
{
     InitializeComponent();
     CheckSerialization();                
     Button btn = btnSerialized;            
}

public void CheckSerialization()
{
     Stream write = File.OpenWrite(@"C:\ser.bin");
     BinaryFormatter serial = new BinaryFormatter();
     serial.Serialize(write, btnSerialized);
     write.Close();
}

private void btnSerialized_Click(object sender, EventArgs e)
{
     FileStream fs = new FileStream(@"C:\ser.bin",FileMode.Open);
     BinaryFormatter bf= new BinaryFormatter();
     object obj = bf.Deserialize(fs);
     Button button12 = (Button)obj;
     button1 = button12;
     button1.Location = new Point(0, 0);
}

类型“system.windows.forms.button”in assembly“system.windows.forms,version=4.0.0.0,culture=neutral,publicKeyToken=b7a5c561934e089”未标记为可序列化。**

如何将此对象标记为可序列化?
