使用Adobe或任何PDF阅读器阅读PDF文件

Question

In my application I have all the PDF in a folder called PDF with names like First.pdf , Second.pdf.

I have LongListSelector with some items in it. When I click on each item I have the selected item value stored in a string.

private void longListSelector_SelectionChanged(object sender, SelectionChangedEventArgs e)
        {
            MyObject item  =  longListSelector.SelectedItem as MyObject;
            MessageBox.Show(item.ST);
        }

The above code gives me names like First , Second .

Now I just want to open the corresponding pdf file with that name.

EDIT

I am working on Windows Phone 8 application and the PDF are in the folder MyPdf inside my app.

**EDIT 1 **

private async void LaunchPDF(string name) 
        {
            StorageFile pdfFile = await Windows.ApplicationModel.Package.Current.InstalledLocation.GetFileAsync("xyz.pdf");
            // Launch the pdf file.
            Windows.System.Launcher.LaunchFileAsync(name);
        }

Getting error in this line Windows.System.Launcher.LaunchFileAsync(name); //has invalid arguments.

Can I use My Emulator to test if the pdf is opening or not ?

Answer 1

您可以使用此组件： PdfViewer ，但该组件不是开源的。

Answer 2

Assuming that the the application is getting developed targeting Windows Phone OS 8.

You can use launcher to open it.

// Get the file
StorageFile pdfFile = await Windows.ApplicationModel.Package.Current.InstalledLocation.GetFileAsync("xyz.pdf");

// Launch the pdf file.
Windows.System.Launcher.LaunchFileAsync(xyz.pdf);
