如何实现IAsyncOperationWithProgress [英] How to implement IAsyncOperationWithProgress

问题描述

我移植了一些自定义.NET流到WinRT的。语言是C＃。

I'm porting some custom .NET streams to WINRT. Language is C#.

有IAsyncOperationWithProgress的一些示例实现？由于方法ReadAsync，WriteAsync从Windows.Storage.Streams需要它们。自定义WinRT的流实现也受到了欢迎。

Is there some example implementation of IAsyncOperationWithProgress? Since Methods ReadAsync, WriteAsync from Windows.Storage.Streams require them. Custom WinRT streams implementations are welcomed also.

我发现使用create_async一些C的例子，但我希望做这在C＃和我找不到在新城框架create_async。

I found some C examples using create_async, but i'm looking to do this in C#, and i cannot find create_async in the Metro framework.

在此先感谢

推荐答案

有关C＃中，你应该检查出的这个//建立在异步编程谈话。

For C#, you should check out this //build talk on async programming.

如果您正在使用高级C ++，你应该看看<一个href=\"http://blogs.msdn.com/b/nativeconcurrency/archive/2011/09/22/windows-8-asynchrony-with-ppl.aspx\"相对=nofollow>有关如何在PPL做异步操作此文章。

If you're using high level C++, you should look at this article about how to do asynchronous operations in the PPL.

如果您需要实现从低级别C ++自己的异步操作，你应该看的 WRL :: AsyncBase 类。

If you need to implement your own async operation from low level C++, you should look at the WRL::AsyncBase class.
