添加大文件IO.Compression.ZipArchiveEntry抛出OutOfMemoryException异常 [英] Adding large files to IO.Compression.ZipArchiveEntry throws OutOfMemoryException Exception

问题描述

我试图通过使用此代码添加一个大的视频文件（〜500MB）到ArchiveEntry：

I am trying to add a large video file(~500MB) to an ArchiveEntry by using this code:

using (var zipFile = ZipFile.Open(outputZipFile, ZipArchiveMode.Update))
{
    var zipEntry = zipFile.CreateEntry("largeVideoFile.avi");
    using (var writer = new BinaryWriter(zipEntry.Open()))
    {
        using (FileStream fs = File.Open(@"largeVideoFile.avi", FileMode.Open))
        {
            var buffer = new byte[16 * 1024];
            using (var data = new BinaryReader(fs))
            {
                int read;
                while ((read = data.Read(buffer, 0, buffer.Length)) > 0)
                {
                    writer.Write(buffer, 0, read);
                }
            }
        }
    }
}

我收到错误

的System.OutOfMemoryException

System.OutOfMemoryException

当writer.Write被调用，alltought我用了一个中间缓冲区....

when writer.Write is called, alltought I used a intermediate buffer....

不知道如何解决这个问题？

Any idea how to solve this?

推荐答案

构建应用程序的任何CPU，并在64位计算机上执行它。这应该可以解决这个问题。 （或者直接构建应用程序为64位）。

Build the application as any CPU and execute it in a x64 machine. This should fix the issue. (Or directly build the application as x64).

视频通常不能被压缩了很多，zip文件可能保留在内存中，直到完全建立。

Videos normally cannot be compressed a lot and the zip file probably remains in memory until the are completely created.
