上传Zip块并在Azure平台上加入它们

Question

public void SplitFile(){
    int numericUpDown = 100;//in MB
    string PathToCopyChunks = "";  // path to store chunks and ( .bat  ) file
    string FilePathMakeChunks = DirectoryNameToPutScannedData; //the path of file to make chunks.
    try{
        int kbs = numericUpDown * 1024;
        int chunkSize = numericUpDown * 1024 * 1024;
        byte[] buffer = new byte[4096];
        string cmdout = "copy/b ";
        FileStream infile = File.OpenRead(FilePathMakeChunks);
        for (long i = 0; i <= infile.Length / chunkSize; i++)
        {
            string fname = Path.Combine(PathToCopyChunks, Path.Combine(PathToCopyChunks, Path.GetFileName(FilePathMakeChunks)) + "." + chunkSize + "." + i.ToString().PadLeft(4, '0') + ".part");
            string fname_x = Path.GetFileName(FilePathMakeChunks) + "." + chunkSize + "." + i.ToString().PadLeft(4, '0') + ".part";
            if (i == infile.Length / chunkSize)
                cmdout += "\"" + fname_x + "\"";
            else
                cmdout += "\"" + fname_x + "\" + ";
            FileStream outfile = File.Create(fname);
            for (int kb = 0; kb <= kbs; kb++)
            {
                int len = infile.Read(buffer, 0, 1024);
                outfile.Write(buffer, 0, len); 
            }
            outfile.Close();
        }
        cmdout += " \"" + Path.GetFileName(FilePathMakeChunks) + "\"";
        string combinerbatch = Path.Combine(PathToCopyChunks, Path.Combine(PathToCopyChunks, Path.GetFileName(DirectoryNameToPutScannedData)) + "." + chunkSize + ".combine.bat");
        File.WriteAllText(combinerbatch, cmdout);
        MessageBox.Show("Splitting Done...!");
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.ToString());
    }
}

我正在将这些块与批处理文件一起上传到azure存储容器中，我希望在我的azure容器中运行这个批处理文件来加入块。希望这有助于理解我的问题

我用这段代码上传

string[] array1 = Directory.GetFiles(@"D:\Test");
string fileName = string.Empty;
foreach (string name in array1)
{
    fileName = Path.GetFileName(name);
    CloudBlockBlob blockBlob = container.GetBlockBlobReference(fileName);
    var fileStream = System.IO.File.OpenRead(name);
    blockBlob.UploadFromStream(fileStream); 
}

Answer 1

有两件事：

1. 如果您希望压缩blob存储中的文件，即在blob存储中上传大文件，并期望blob存储在那里压缩这些文件，那么这是不可能的。Blob存储是简单的文件存储。
2. 如果您有一个大的zip文件，您想要分块上载，然后让blob存储重新组合这些块来创建zip文件，那么这是可能的。

由于您没有提到要使用的技术，所以我将使用Azure REST API来描述这个过程。
