FileStream在使用statment时关闭VS FileStream [英] FileStream close VS FileStream in using statment

问题描述

我们遇到的问题是，有时文件没有完全写入（所有数据），我们使用的是以下代码

we were facing a problem that sometime the file was not written completely (all the data) and we were using code below

using (FileStream fs = new FileStream(tempFileName, FileMode.Create))
                {
                    BinaryWriter writer = new BinaryWriter(fs);
                    writer.Flush();
                    writer.Write(data);
                }  

我只做了解决这个问题的事情

only thing i did to solve the situation is put

fs.Close();

在using语句中，它开始按预期工作。现在按照MSDN的说法，diposed会在内部调用close。



知道为什么会出现这种奇怪的行为吗？

inside using statement and it's started working as expected. now as per MSDN says diposed does call close internally.

any idea why this strange behavior ?

推荐答案

将您的代码更改为以下代码。

Change your code to below code.

using (FileStream fs = new FileStream(tempFileName, FileMode.Create))
{
      BinaryWriter writer = new BinaryWriter(fs);
      writer.Write(data);
      writer.Flush();
}  

写完后刷新（）。

Do a Flush() after write.
