当我尝试将多个文件（以块为单位）上传到Windows Azure时，只会保存最新的文件。
我跟着this教程（工作正常）和一个文件。当我选择多个文件并开始上传它们时，当我将阻止列表放入blob文件时，它总是在Commit方法中崩溃。

当我搜索“指定的阻止列表无效”时，我发现了一些像here这样的技巧来设置所有阻止ID的长度相同但它不起作用。
例如： 我改变了这段代码：
var id = Convert.ToBase64String(BitConverter.GetBytes(index));
到
var id = Convert.ToBase64String(Encoding.UTF8.GetBytes(index.ToString("d8")));
更新：完整代码 的 Azure.js
$(function () {
$("#upload").click(function () {
//get GUID
var guid = $("#getID").val();
// start to upload each files in chunks
var test = $("#dropzone-files");
var files = $("#dropzone-files")[0].dropzone.files;
for (var i = 0; i < files.length; i++) {
var file = files[i];
var fileSize = file.size;
var fileName = guid + "_" + file.name;
// calculate the start and end byte index for each blocks(chunks)
// with the index, file name and index list for future using

var blockSize = blockSizeInKB * 1024;
var blocks = [];

var index = 0;

var end = Math.min(offset + blockSize, fileSize);
blocks.push({

list += index + ",";
offset = end;
index++;

var putBlocks = [];
blocks.forEach(function (block) {
putBlocks.push(function (callback) {
