Methods

The HttpMultipartContent class has these methods. With C#, Visual Basic, and C++, it also inherits methods from the Object class.

MethodDescription
Add Add HTTP content to the HttpMultipartContent instance.
BufferAllAsync Serialize the HttpMultipartContent into memory as an asynchronous operation.
Close [C++, JavaScript]Closes the HttpMultipartContent instance and releases allocated resources.
Dispose [C#, VB]Performs tasks associated with freeing, releasing, or resetting unmanaged resources.
First [C++, JavaScript]Gets an object that can be used to enumerate the contents in the HttpMultipartContent object.
ReadAsBufferAsync Serialize the HttpMultipartContent to a buffer as an asynchronous operation.
ReadAsInputStreamAsync Serialize the HttpMultipartContent and return an input stream that represents the content as an asynchronous operation.
ReadAsStringAsync Serialize the HttpMultipartContent to a String as an asynchronous operation.
ToString Returns a string that represents the current HttpMultipartContent object.
TryComputeLength Determines whether the HttpMultipartContent has a valid length in bytes.
WriteToStreamAsync Write the HttpMultipartContent to an output stream as an asynchronous operation.

 

Properties

PropertyAccess typeDescription

Headers

Read-onlyGet a collection of content headers set on the HttpMultipartContent.

 

Remarks

Enumerating the collection in C# or Microsoft Visual Basic

You can iterate through an HttpMultipartContent object in C# or Microsoft Visual Basic. In many cases, such as using foreach syntax, the compiler does this casting for you and you won't need to cast to IEnumerable<IHttpContent> explicitly. If you do need to cast explicitly, for example if you want to call GetEnumerator, cast to IEnumerable<T> with an IHttpContent constraint.
