wpf单击按钮在Adobe Reader中打开PDF文件

Question

I need a button to open a PDF file with Adobe Reader. I have the following code but it does not work. The file is inside Books folder on my application.

private void openPDF(object sender, RoutedEventArgs e)
{
    try
    {
        System.Diagnostics.Process process = new System.Diagnostics.Process();
        bookPDF = "/Books/" + dataRow.ItemArray[6].ToString();
        Uri pdf = new Uri(bookPDF, UriKind.Relative);
        process.StartInfo.FileName = new Uri(bookPDF, UriKind.Relative).ToString();
        process.Start();
        process.WaitForExit();
    }
    catch
    {
        MessageBox.Show("Could not open the file.", "Error", MessageBoxButton.OK, MessageBoxImage.Warning);
    }
}

I tested a simple string with a test pdf file to open and it opens.

...
String file = "C:\\pdf\\Windows_Server_2008_R2_Unleashed.pdf";
process.StartInfo.FileName = file;
process.Start();
process.WaitForExit();

Answer 1

Change your 6th line:

bookPDF = "/Books/" + dataRow.ItemArray[6].ToString();

to:

bookPDF = "Books\\" + dataRow.ItemArray[6].ToString();

Microsoft Windows naming convention uses backslashes as separator within paths https://msdn.microsoft.com/en-us/library/windows/desktop/aa365247%28v=vs.85%29.aspx

Answer 2

You can change your 6th line to :

bookPDF = string.Format(@"books\{0}", dataRow.ItemArray[6].ToString());         

And this should work if you have books folder in your application directory which has specified pdf.
