开始写入的偏移量（以字节为单位）。
- contentMD5
- String
一个可选哈希值，用于设置 ContentMD5 文件上的 属性。 可以是 null 或空字符串。
- accessCondition
- AccessCondition
一个表示文件访问条件的 AccessCondition 对象。 如果为 null，则不使用任何条件。
- options
- FileRequestOptions
一个 FileRequestOptions 对象，它指定请求的其他选项。
- operationContext
- OperationContext
一个 OperationContext 对象，它一个表示当前操作的上下文。
- callback
- AsyncCallback
在异步操作完成时接收通知的回调委托。
- state
- Object
将传递给回调委托的用户定义对象。
返回
