如何创建基本包来存储图像？ [英] How to create a basic package to store images ?

问题描述

如何创建基本包来存储图像？像一个zip文件。我想要的只是在一个包中存储20000个图像。我的硬盘更容易。此外，我需要能够使用c＃代码进入和退出该包，读/写，添加或删除文件。另一种文件格式是.iso，它接近我想要的，但操作起来很复杂。我想要一些非常基本但不复杂的东西。如果可能，基本作为库。有这样的事吗？谢谢！



我的尝试：



与这种情况。

How to create a basic package to store images ? Like a zip file. All i want is to store 20000 images inside one package. Is easier for my hard disk. Also, I need to be able to enter and get out from that package, to read/write , add or remove files, using c# code. Another file format is .iso that is close to what I want, but is complicated to operate with it. I want something very basic, not complicated. Basic as a library if possible. Is there such a thing? Thank you!

What I have tried:

推荐答案

您可以在.NET中创建和管理zip文件，参见ZipFile Class（System.IO.Compression） [ ^ ]。

You can create and manage zip files in .NET, see ZipFile Class (System.IO.Compression)[^].

使用.NET 4.5提供的System.IO.Compression中的ZipArchive类：[ ^ ]。

Use the ZipArchive Class in System.IO.Compression available with .NET 4.5: [^].

Create a zip archive from a directory
ZipFile.CreateFromDirectory

Extract the contents of a zip archive to a directory
ZipFile.ExtractToDirectory

Add new files to an existing zip archive
ZipArchive.CreateEntry

Retrieve a file from a zip archive
ZipArchive.GetEntry

ZipArchive.Entries
Retrieve all the files from a zip archive

ZipArchiveEntry.Open
Open a stream to a single file contained in a zip archive

ZipArchiveEntry.Delete
Delete a file from a zip archive

谢谢大家的支持输入，它帮助我决定并指导我在许多网络搜索战斗后找到这个答案。



我找到了一个实用的解决方案，但不是那个我希望它有效率。

从zip文件中循环播放图像时移动速度慢，因为它正在解压缩每个文件。我必须重新考虑代码并将其全部解压缩到流或某些列表中。我再看看吧。现在，正在工作，我很高兴:)



这是我想出的结果：

Thank you all for your input, it helped me decide and it direction me to this answer I find after many web search battles.

I find a practical solution, but not that efficient as I want it.
Is moving slow-ish when cycling the images from inside a zip file, because it is unpacking each of them. I must re-think the code and unzip all into a stream or some lists. I will see. For now, is working and I am very happy :)

Here is the result I came up with:

//My code so far - not very efficient but is working.
using Ionic.Zip;
using Ionic.Zlib;

        string zipPath = "0Images.zip";
        void CountZipFiles()
        {
            using (ZipFile zip = new ZipFile(zipPath))
            {
                totalzipFiles = zip.Count-1;
            }
        }
        Image emptyImage = Image.FromFile("emptyFemale.jpg");
        void ReadZipImage()
        {
            using (ZipFile zip = new ZipFile(zipPath))
            {
                MemoryStream tempS = new MemoryStream();
                for (int i = 0; i < zip.Count; i++)
                {
                    if (i == countMyZipImages)
                    {
                        label1.Text = zip[i].FileName;
                        if (zip[i].FileName.Contains(".niet"))
                        {
                            pictureBox1.Image = emptyImage;
                        }
                        else
                        {
                            zip[i].Extract(tempS);
                            pictureBox1.Image = Image.FromStream(tempS);
                        }
                    }
                }
            }
        }

        int totalzipFiles = 0, countMyZipImages = 0;
        private void button2_Click(object sender, EventArgs e)
        {
            countMyZipImages--;
            if (countMyZipImages < 0) countMyZipImages = totalzipFiles;
            textBox1.Text = countMyZipImages.ToString();
            ReadZipImage();
        }
        private void button3_Click(object sender, EventArgs e)
        {
            countMyZipImages++;
            if (countMyZipImages > totalzipFiles) countMyZipImages = 0;
            textBox1.Text = countMyZipImages.ToString();
            ReadZipImage();
        }

How to add Ionic.Zip.dll in c#.net project and use it:

To add a reference, right click (in Solution Explorer on your project) Reference folder and select Add Reference.
Then browse and add the file Ionic.Zip.dll

//Important to add this using's too after referencing.
using Ionic.Zip;
using Ionic.Zlib;


        private void CreateZIP_Click(object sender, EventArgs e)
        {
            using (ZipFile zip = new ZipFile())
            {
                // add this map file into the "images" directory in the zip archive
                zip.AddFile("c:\\images\\personal\\7440-N49th.png", "images");
                // add the report into a different directory named "files" in the archive
                zip.AddFile("c:\\Reports\\2008-Regional-Sales-Report.pdf", "files");
                zip.AddFile("ReadMe.txt");
                zip.Save("MyZipFile.zip");
                
                Exception ex = new Exception();
                label1.Text = ex.Message;
            }
        }


		//You can extract to a stream, or a fizical file ! 
        private void button5_Click(object sender, EventArgs e)
        {
            using (ZipFile zip = new ZipFile("0Images.zip"))
            {
                MemoryStream tempS = new MemoryStream(); //stream
                
          //{      
                foreach (ZipEntry ze in zip)		//foreach
                {
                    // check if you want to extract the image.name 
                    if (ze.FileName == "00002 Riley Reid.jpg")
                    {
                        ze.Extract(tempS);
                        pictureBox1.Image = Image.FromStream(tempS);
                    }
                }
           //OR
                for (int i = 0; i < zip.Count; i++)	//for
                {
                    if (i == countMyZipImages)
                    {
                        zip[i].Extract(tempS);
                        pictureBox1.Image = Image.FromStream(tempS);
                    }
                }
           //}     
                
            }
