.Net MVC控制器调用上传：

七牛文档中心：http://developer.qiniu.com/

我就是做了一个页面使用API上传文件，然后获取上传的文件链接用在QQ空间，说一下使用音乐的步骤。

花几分钟做了个简单的使用教程。

个人后台登陆地址：/Admin/Auth/Login

.Net Code：

    public class UploadEventArgs : EventArgs//作为事件的参数，必须派生自EventArgs基类
    {
        public UploadEventArgs(int percent)
        {
            this.Percent = percent;
        }
        public int Percent { get; set; }
    }
    public class Upload
    {
        public event EventHandler<UploadEventArgs> Uploading;//定义事件,上传中实时通知上传进度
        public int Percent{get;private set;}
        public Upload()
        {
            Percent = 0;
        }
        public void DoUpload()
        {
            UploadEventArgs ev=new UploadEventArgs(0);
            while(Percent<100)
            {
//上传文件代码简单，就不写出了

动态分配内存：头文件 stdlib.h

    malloc：分配内存

    calloc：分配内存，并清零

    realloc：调整已分配的内存块大小

    示例：

        int *p=(int *) malloc(3*sizeof(int));//分配内存，成功返回首地址，失败返回NULL
