因前几日见园子里有人说可以把网站静态文件放在百度上，于是去百度开放平台看了看，发现之前那篇文章不是调的云存储接口啊。。。
于是自己写了个C#能调百度云存储的例子（百度云开放平台只提供php、java、Python、c++），下面贴一下步骤和代码，还请多多指点啊！
一、
百度提供的四种途径我们选择的是curl方式，但是大家都知道curl需要linux环境支持，这里引用了国外的开源项目。下载最新版本的libcurlnet-1_3.zip，解压后将这（ca-bundle.crt、libcurl.dll、LibCurlNet.dll、LibCurlShim.dll）四个文件放在你自己项目的bin目录下。
然后项目里添加LibCurlNet.dll引用。
二、签名算法
百度的URL签名算法说是用的sha1加密，千万别理解错！这里我是从php的hash_hmac算法转的，代码如下：
1 /// <summary> 2 /// hmacSha1算法加密 3 /// </summary> 4 /// <param name="encryptText">加密明文</param> 5 /// <param name="encryptKey">加密密钥</param> 6 /// <returns></returns> 7 public static string hmacSha1(string encryptText, string encryptKey) 8 { 9 HMACSHA1 myHMACSHA1 = new HMACSHA1(Encoding.Default.GetBytes(encryptKey));10 byte[] RstRes = puteHash(Encoding.Default.GetBytes(encryptText));11 return Convert.ToBase64String(RstRes);12 }

三、实现curl上传
其实就是要将下面这段命令翻译成C#
curl -T bs.txt -v "/bucket/testobject?sign=MBO:f:PVaOdaf%2BxNoC7aXRqL%2FJq5Kp7a4%3D"
废话不多直接上代码

至于具体咋用，我这儿真没什么资料，都谷歌上查的，兄弟们有相关资料的给留个地址啊，我这还想继续完善完善啊。。。
