如何在Windows应用商店应用中访问文件！ [英] How Can I Access File In Windows Store App!

问题描述

嗨！

如何在不使用FileOpenPicker控件的Windows应用商店中访问文件。

在c＃中这样：

< pre lang =c＃> string [] filelist = Directory.GetFiles（ @ d：\）;
FileStream fs = new FileStream（ @ D：\ab.jpg，FileMode.OpenOrCreate，FileAccess.ReadWrite）;
FileStream fs2 = new FileStream（filelist [ 0 ]，FileMode.OpenOrCreate，FileAccess.ReadWrite ）;

谢谢！

解决方案

我想您可以尝试访问appData下LocalFolder下的选项。例如，有一些方法，如CreateFile，GetFileAsync，OpenFileAsync等。



等待ApplicationData.Current.LocalFolder.CreateFileAsync（fileName，CreationCollisionOption.ReplaceExisting）;





尝试使用GetFileAsync并根据您是否获得有效的o / p或命中异常，您可以继续前进。

Hi!
How can i access file in Windows store app not using the FileOpenPicker control.
Like this in c#:

string [] filelist = Directory.GetFiles(@"d:\");
FileStream fs = new FileStream(@"D:\ab.jpg", FileMode.OpenOrCreate, FileAccess.ReadWrite);
FileStream fs2 = new FileStream(filelist[0], FileMode.OpenOrCreate, FileAccess.ReadWrite);

Thank you!

解决方案

I think you can try accessing options under the LocalFolder under your appData. For example there are methods like CreateFile, GetFileAsync, OpenFileAsync etc.

await ApplicationData.Current.LocalFolder.CreateFileAsync(fileName, CreationCollisionOption.ReplaceExisting);


Try using GetFileAsync and based whether you get a valid o/p or hit exceptions you can move forward with what you want to do.
