Hi,

Is is possible to programmatically flush all opened files ??

Peter

推荐答案

你好彼得，


你是什么意思冲洗所有打开的文件？当使用流打开.NET

框架中的文件时，我们可以调用其Flush方法来清除此流的所有缓冲区

，并将任何缓冲的数据写入

底层设备。你想要冲洗吗？在.NET

应用程序中打开的所有文件？根据我的研究，我们需要冲洗文件一个接一个

因为他们使用不同的Stream。有关.NET框架中的文件和流

I / O的更多信息，您可以参考：

如果还有其他问题，请随时告诉我们。


此致，

Hello Peter,

What did you mean "Flush" all opened files? When opening a file in .NET
framework with stream, we can call its Flush method to clears all buffers
for this stream and causes any buffered data to be written to the
underlying device. Did you want "flush" all files opened in a .NET
application? Based on my research, we need to "flush" the files one by one
since they use different Stream. For more information about File and Stream
I/O in .NET framework, you may refere to:

http://msdn2.microsoft.com/en-us/lib...4t(VS.80).aspx

If there is any further questions, please feel free to let us know.

Sincerely,

Luke Zhang

你好卢克，


让我重新解释这个问题。 br />

是否可以在本地PC上禁用文件缓存 - 通过更改注册表

键或类似名称？

我已阅读关于控制网络缓存的一些注册表项，但是没有人来控制本地缓存。


我想要这种非chache状态的原因是我想要测试文件

访问速度。


BR

彼得

Hi Luke,

Let me rephrase the question.

Is it possible to disable file cache on a local PC - by changing a registry
key or similar ?
I have read about some registry keys to control network cache, but no one to
control local cache.

The reason for i want this non-chache state is that i want to test file
access speed.

BR
Peter

Hello Peter，

在.NET应用程序中打开文件时，.NET应用程序提供/控制缓存

，不是操作系统（因此没有注册表可以禁用

缓存）。你能解释一下如何在.NET

应用程序中测试访问速度吗？也许我们可以找到避免缓存的影响。

Luke Zhang

Hello Peter,

When you open a file in .NET application, the cache is provided/controled
by .NET application, not the OS (So there is no a registry to disable
cache). Can you explain more on how you test the access speed in a .NET
application? Maybe we can find to avoid the impact of cache.
