.NET GZipStream，以及磁盘空间不足异常

我正在使用以下代码写入每次创建新的压缩文件。

using (FileStream fs = File.Open(sortOrderFileName, FileMode.Create,FileAccess.Write, FileShare.ReadWrite))
using (System.IO.Compression.GZipStream gzip = new System.IO.Compression.GZipStream(fs, System.IO.Compression.CompressionMode.Compress))
using (StreamWriter sw = new StreamWriter(gzip))
{
     // use the streamwriter sw to write to the stream
}

但是，当我运行此命令时，我收到 IOException 并显示消息“磁盘空间不足”。但是，我正在写入文件的驱动器上有 19GB 的可用空间。

根据 GZipStream 的文档，它不能用于写入大于 4GB 的文件。然而，到目前为止写入的文件大小只有250MB。

这是异常：

类型：System.IO.IOException 异常消息：磁盘空间不足。

内部异常： StackTrace：位于 System.IO.__Error.WinIOError（Int32 errorCode，String MaybeFullPath）在 System.IO.FileStream.WriteCore（Byte[] 缓冲区，Int32 偏移量，Int32 计数）在 System.IO.FileStream.FlushWrite（布尔称为FromFinalizer）在 System.IO.FileStream.Dispose（布尔处置）在 System.IO.Stream.Close() 在 System.IO.Compression.DeflateStream.Dispose（布尔处置）在 System.IO.Stream.Close() 在 System.IO.Compression.GZipStream.Dispose（布尔处置）在 System.IO.Stream.Close() 在 System.IO.StreamWriter.Dispose（布尔处置） at System.IO.StreamWriter.Close()

另外，这不是网络文件。

有什么想法我在这里做错了吗？

原文

I am using the following code to write to a compressed file that I create new everytime.

using (FileStream fs = File.Open(sortOrderFileName, FileMode.Create,FileAccess.Write, FileShare.ReadWrite))
using (System.IO.Compression.GZipStream gzip = new System.IO.Compression.GZipStream(fs, System.IO.Compression.CompressionMode.Compress))
using (StreamWriter sw = new StreamWriter(gzip))
{
     // use the streamwriter sw to write to the stream
}

However, when I run this, I am getting an IOException with the message "Out of disk space". However, there is 19GB of space available on the drive on which I am writing the file.

According to the docs for GZipStream, it cannot be used to write a file greater than 4GB. However, the file written till now is only 250MB in size.

Here is the exception:

Type: System.IO.IOException
Exception Msg: There is not enough space on the disk.

Inner Exception:
StackTrace: at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)
at System.IO.FileStream.WriteCore(Byte[] buffer, Int32 offset, Int32 count)
at System.IO.FileStream.FlushWrite(Boolean calledFromFinalizer)
at System.IO.FileStream.Dispose(Boolean disposing)
at System.IO.Stream.Close()
at System.IO.Compression.DeflateStream.Dispose(Boolean disposing)
at System.IO.Stream.Close()
at System.IO.Compression.GZipStream.Dispose(Boolean disposing)
at System.IO.Stream.Close()
at System.IO.StreamWriter.Dispose(Boolean disposing)
at System.IO.StreamWriter.Close()

Also, this is not a network file.

Any ideas what I am doing wrong here?
