Answer 1

Hi,

Windows 8.1没有直接的API可以支持分布加载。但是在windows 8.1 的PDF API里面有一个PdfDocument.LoadFromStreamAsync(IRandomAccessStream)方法是根据流来实现PDF文件的加载。如果您想实现分布加载，可以在读取文件的时候以流的形式读取PDF文件的内容，然后再分割文件流，根据分割后的流来分布加载PDF。

祝您好运！

Hi，

windows 8.1里面只能提供简单的PDF文件处理的API。关于分布加载没有直接的方法。您可以寻求第三方的

Answer 3

你是在用预览版Windows 8.1么？使用正式版Windows 8.1和Visual Studio 2013，运行PDFAPI CPP示例无法重现你的问题

Answer 4

如同蒋晟所言，用C#代码重现了一下，读取一个140M大小的PDF并未出现异常，并且只消耗15M内存。

能具体说明下你的问题么，比如说打开了PDF文件之后做了什么样的后续动作，或者你可以试一下比较小的文件看看是否有相同的问题存在。一般Store App会有大小限制，我猜想是否是因为你后续展示文件的时候超过了应用可使用的内存上限导致程序崩溃。
