Constructors

HttpContent()

Initializes a new instance of the HttpContent class.

protected HttpContent()

Properties

Headers

Gets the HTTP content headers as defined in RFC 2616.

public HttpContentHeaders Headers { get; }

Property Value

HttpContentHeaders

The content headers as defined in RFC 2616.

Methods

CopyTo(Stream)

Serializes the HTTP content into a stream of bytes and copies it to stream.

public void CopyTo(Stream stream)

Parameters

stream Stream

The target stream.

Remarks

This is the .NET nanoFramework equivalent of HttpContent.CopyTo(Stream, TransportContext, CancellationToken).

Exceptions

ArgumentNullException

The stream was null.

CreateContentReadStream()

If overridden, returns the HTTP content as a stream. Otherwise, SerializeToStream(Stream) is called.

protected virtual Stream CreateContentReadStream()

Returns

Stream

Remarks

This is the .NET nanoFramework equivalent of CreateContentReadStreamAsync().

Dispose()

Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.

public void Dispose()

Dispose(bool)

protected virtual void Dispose(bool disposing)

Parameters

disposing bool

LoadIntoBuffer()

Serialize the HTTP content to a memory buffer.

public void LoadIntoBuffer()

Remarks

This operation will block.

After content is serialized to a memory buffer, calls to one of the CopyTo methods will copy the content of the memory buffer to the target stream.

This is the .NET nanoFramework equivalent of LoadIntoBufferAsync.

Exceptions

ObjectDisposedException

If the object has been disposed.

ReadAsByteArray()

Serialize the HTTP content to a byte array as an synchronous operation.

public byte[] ReadAsByteArray()

Returns

byte[]

A byte array with the HTTP content.

Remarks

This operation will block.

This is the .NET nanoFramework equivalent of ReadAsByteArrayAsync.

ReadAsStream()

Serializes the HTTP content and returns a stream that represents the content.

public Stream ReadAsStream()

Returns

Stream

The stream that represents the HTTP content.

Exceptions

ObjectDisposedException

If the object has been disposed.

ReadAsString()

Serialize the HTTP content to a string as an synchronous operation.

public string ReadAsString()

Returns

string

A string with the HTTP content.

Remarks

This operation will block.

This supports only UTF8 encoding.

This is the .NET nanoFramework equivalent of ReadAsStringAsync.

SerializeToStream(Stream)

When overridden in a derived class, serializes the HTTP content to a stream. Otherwise, throws a NotSupportedException.

protected abstract void SerializeToStream(Stream stream)

Parameters

stream Stream

The target stream.

Remarks

This is the .NET nanoFramework equivalent of SerializeToStream(Stream, TransportContext, CancellationToken).

Exceptions

NotSupportedException

The method is not overridden in the derived class.

TryComputeLength(out long)

Determines whether the HTTP content has a valid length in bytes.

protected abstract bool TryComputeLength(out long length)

Parameters

length long

The length in bytes of the HTTP content.

Returns

bool

true if length is a valid length; otherwise, false.
