Methods

BufferAllAsync() BufferAllAsync() BufferAllAsync() BufferAllAsync()

Serialize the HttpStringContent into memory as an asynchronous operation.

public : IAsyncOperationWithProgress<ulong, ulong> BufferAllAsync()public IAsyncOperationWithProgress<ulong, ulong> BufferAllAsync()Public Function BufferAllAsync() As IAsyncOperationWithProgress( Of ulong, ulong )// You can use this method in JavaScript.
Returns

Remarks

This operation will not block. The returned IAsyncOperationWithProgress(UInt64, UInt64) object will complete after all of the content has been written into memory.

Close() Close() Close() Close()

Closes the HttpStringContent instance and releases allocated resources.

public : void Close()This member is not implemented in C#This member is not implemented in VB.Net// You can use this method in JavaScript.

Remarks

The Close method releases allocated resources used by the HttpStringContent instance. The Close method can manage the lifetime of system resources (memory for the HttpStringContent, for example) used by a Windows Runtime object.

In the .NET Framework 4.5, this method projects as the Dispose method. In Visual C++ component extensions (C++/CX), this method projects as the destructor (delete operator).

Apps written in JavaScript, C#, or VB.NET use garbage collection to release resources. So the HttpStringContent object and associated resources doesn't get released until the garbage collection pass runs. The Close method allows an app to release these resources early rather than waiting for the object to be released by garbage collection.

Apps written in C++ or CX don't have a Close method since these apps can destroy the object. In C++ and CX, objects are released when they fall out of program scope or as part of the destructor (delete operator) for the object.

Dispose() Dispose() Dispose() Dispose()

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

This member is not implemented in C++void Dispose()Sub Disposevoid Dispose()

ReadAsBufferAsync() ReadAsBufferAsync() ReadAsBufferAsync() ReadAsBufferAsync()

Serialize the HttpStringContent to a buffer as an asynchronous operation.

public : IAsyncOperationWithProgress<IBuffer, ulong> ReadAsBufferAsync()public IAsyncOperationWithProgress<IBuffer, ulong> ReadAsBufferAsync()Public Function ReadAsBufferAsync() As IAsyncOperationWithProgress( Of IBuffer, ulong )// You can use this method in JavaScript.
Returns

Remarks

This operation will not block. The returned IAsyncOperationWithProgress(IBuffer, UInt64) object will complete after all of the content has been written to the buffer.

ReadAsInputStreamAsync() ReadAsInputStreamAsync() ReadAsInputStreamAsync() ReadAsInputStreamAsync()

Serialize the HttpStringContent and return an input stream that represents the content as an asynchronous operation.

public : IAsyncOperationWithProgress<IInputStream, ulong> ReadAsInputStreamAsync()public IAsyncOperationWithProgress<IInputStream, ulong> ReadAsInputStreamAsync()Public Function ReadAsInputStreamAsync() As IAsyncOperationWithProgress( Of IInputStream, ulong )// You can use this method in JavaScript.
Returns

Remarks

This operation will not block. The returned IAsyncOperationWithProgress(IInputStream, UInt64) object will complete after all of the content has been written to the stream.

ReadAsStringAsync() ReadAsStringAsync() ReadAsStringAsync() ReadAsStringAsync()

Serialize the HttpStringContent to a String as an asynchronous operation.

public : IAsyncOperationWithProgress<PlatForm::String, ulong> ReadAsStringAsync()public IAsyncOperationWithProgress<string, ulong> ReadAsStringAsync()Public Function ReadAsStringAsync() As IAsyncOperationWithProgress( Of string, ulong )// You can use this method in JavaScript.
Returns

The object that represents the asynchronous operation.

Remarks

This operation will not block. The returned IAsyncOperationWithProgress(String, UInt64) object will complete after all of the content has been written to the String.

ToString() ToString() ToString() ToString()

Returns a string that represents the current HttpStringContent object.

public : PlatForm::String ToString()public string ToString()Public Function ToString() As string// You can use this method in JavaScript.
Returns
PlatForm::String string string string

A string that represents the current object.

TryComputeLength(UInt64) TryComputeLength(UInt64) TryComputeLength(UInt64) TryComputeLength(UInt64)

Compute the HttpStringContent length in bytes.

public : PlatForm::Boolean TryComputeLength(unsigned __int64 length)public bool TryComputeLength(UInt64 length)Public Function TryComputeLength(length As UInt64) As bool// You can use this method in JavaScript.
Parameters
length
unsigned __int64 UInt64 UInt64 UInt64

The length in bytes of the HttpStringContent.

Returns
PlatForm::Boolean bool bool bool

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

The return value should never be false.

Remarks

The TryComputeLength method calculates the content length for HTTP content in HttpStringContent. Headers set on the content are not included in the content length. This is useful for content types that are easy to calculate the content length.

WriteToStreamAsync(IOutputStream) WriteToStreamAsync(IOutputStream) WriteToStreamAsync(IOutputStream) WriteToStreamAsync(IOutputStream)

Write the HttpStringContent to an output stream as an asynchronous operation.

public : IAsyncOperationWithProgress<ulong, ulong> WriteToStreamAsync(IOutputStream outputStream)public IAsyncOperationWithProgress<ulong, ulong> WriteToStreamAsync(IOutputStream outputStream)Public Function WriteToStreamAsync(outputStream As IOutputStream) As IAsyncOperationWithProgress( Of ulong, ulong )// You can use this method in JavaScript.
Parameters
outputStream
IOutputStream IOutputStream IOutputStream IOutputStream

The output stream to write to.

Returns

Remarks

This operation will not block. The returned IAsyncOperationWithProgress(UInt64, UInt64) object will complete after all of the content has been written to the output stream.
