使用序列化将我的对象序列化到硬盘驱动器 [英] using serialization to serialize my objects to hard drive

问题描述

嘿我正在使用序列化将我的对象序列化为硬盘驱动器，

读取它们没问题但是覆盖它们会导致我出现问题，我有点b / b
未经授权访问文件，但我给了文件夹所有的

权限。


来源：
http://www.vkarlsen.no/pastebin/default.asp?id=5545


有人能告诉我我做得不对吗

解决方案

这只会在我写一个新文件时发生然后尝试重写它。

如果线程完成并启动overagain我能够覆盖已经存在的

文件，这是我想要的。

请准确发布异常消息。

您还应该发布完整的代码，说明您有什么问题，而不是像现在这样的一些方法。

您使用文件流写入磁盘吗？是否在手动清理使用区块/

？以下示例不会出错。删除

''使用''块，你得到一个文件锁定异常：


"'System.IO类型的未处理异常。 IOException''发生在

mscorlib.dll


附加信息：进程无法访问文件I：\ x.dat

因为它被另一个进程使用。


static void Main（string [] args）

{

WriteFile（）;

WriteFile（）;

Console.Read（）;

}

static void WriteFile（）

{

Foo foo = new Foo（）;

BinaryFormatter bf = new BinaryFormatter（）;

using（FileStream fs = new FileStream（@I：\ x.dat"，FileMode.Create））

{

bf.Serialize （fs，foo）;

}

}

Hey im using serialization to serialize my objects to hard drive,
reading them is no problem but overwriting them causes me problems,i
have un authorized access to the files but i gave the folder all the
permissions.

source:
http://www.vkarlsen.no/pastebin/default.asp?id=5545

can someone tell me what im not doing right

解决方案

this only occurs when i write a new file and then try to over write it.
if the thread finishes and starts overagain i am able to overwrite a
file that already exists as often as i want..

Please post the exact exception message.
You should also post the complete code that illustrates the problem you
have, not a few methods like you did now.

Are you using a filestream to write to disk? Is it in a using block /
being cleaned up manually? The example below does not error. Remove the
''using'' block, and you get a file locked exception:

"An unhandled exception of type ''System.IO.IOException'' occurred in
mscorlib.dll

Additional information: The process cannot access the file "I:\x.dat"
because it is being used by another process."

static void Main(string[] args)
{
WriteFile();
WriteFile();
Console.Read();
}
static void WriteFile()
{
Foo foo = new Foo();
BinaryFormatter bf = new BinaryFormatter();
using(FileStream fs = new FileStream(@"I:\x.dat",FileMode.Create))
{
bf.Serialize(fs,foo);
}
}
