unsigned long long
uint64_t
The length in bytes of the HTTP content.
bool
true if length is a valid length; otherwise, false.
The TryComputeLength method calculates the content length for HTTP content in IHttpContent. This is useful for content types that are easy to calculate the content length.
If computing the content length is not possible or expensive (would require the system to buffer the whole content where the serialization would be expensive or require the system to allocate a lot of memory), this method can return false. If this method returns false, this implies that either chunked transfer is needed or the content must get buffered before being sent to the server.
