注解

) HttpBufferContent 类发送 (POST 方法时， HttpProgress.BytesSent 值从发送的 0% 字节跃至在一个进度事件中发送的 100% 字节，因为整个缓冲区一次移动到较低的网络 API。 有关更详细的进度，请使用 HttpStreamContent 而不是 HttpBufferContent，因为流是以较小的区块读取和发送的，从而产生更多的进度事件。 例如发送了 0 个字节、发送了 65536 个字节、131072个发送的字节等。

构造函数

HttpBufferContent(IBuffer)

使用指定的缓冲区初始化 HttpBufferContent 类的新实例。
HttpBufferContent(IBuffer, UInt32, UInt32)

使用来自指定缓冲区的偏移量和字节计数初始化 HttpBufferContent 类的新实例。

将 HttpBufferContent 序列化为 字符串 作为异步操作。
ToString()

返回表示当前 HttpBufferContent 对象的字符串。
TryComputeLength(UInt64)

计算 HttpBufferContent 长度（以字节为单位）。
