Properties

PayloadLength

Get the total length of the payload in bytes.

Declaration

public abstract int PayloadLength { get; }

Property Value

Type	Description
System.Int32

Methods

PayloadAsNewBuffer()

Gets the entire payload as a newly allocated byte array. Once the byte array is returned, the byte array becomes owned by the caller and won't be ever accessed or reused by gRPC again. NOTE: Obtaining the buffer as a newly allocated byte array is the simplest way of accessing the payload, but it can have important consequences in high-performance scenarios. In particular, using this method usually requires copying of the entire buffer one extra time. Also, allocating a new buffer each time can put excessive pressure on GC, especially if the payload is more than 86700 bytes large (which means the newly allocated buffer will be placed in LOH, and LOH object can only be garbage collected via a full ("stop the world") GC run). NOTE: Deserializers are expected not to call this method more than once per received message (as there is no practical reason for doing so) and DeserializationContext implementations are free to assume so.

Declaration

public virtual byte[] PayloadAsNewBuffer()

Returns

Type	Description
System.Byte[]	byte array containing the entire payload.
