The Load method implements the following algorithm for determining the character encoding or character set of the XML document: If there is a 2-byte Unicode byte-order mark, it assumes the encoding is UTF It can handle both big endian and little endian. It can handle both big endian and lttle endian.
The OpenFileDialog Whenever you open or save a file in almost any Windows application, you will see roughly the same dialogs for doing that.
The reason is of course that these dialogs are a part of the Windows API and therefore also accessible to developers on the Windows platform. For WPF, you will find standard dialogs for both opening and saving files in the Microsoft.
In this article we'll focus on the OpenFileDialog class, which makes it very easy to display a dialog for opening one or several files.
Depending on which version of Windows you're using and the theme selected, it will look something like this: The ShowDialog will return a nullable boolean value, meaning that it can be either false, true or null.
If the user selects a file and presses "Open", the result is True, and in that case, we try to load the file into the TextBox control. Filter Normally when you want your user to open a file in your application, you want to limit it to one or a couple of file types.
For instance, Word mostly opens Word file with the extension. You can specify a filter for your OpenFileDialog to indicate to the user which types of file they should be opening in your application, as well as limiting the files shown for a better overview.
This is done with the Filter property, which we can add to the above example, right after initializing the dialog, like this: Notice how the dialog now has a combo box for selecting the file types, and that the files shown are limited to ones with the extension s specified by the selected file type.
The format for specifying the filter might look a bit strange at first sight, but it works by specifying a human-readable version of the desired file extension s and then one for the computer to easily parse, separated with a pipe character.
If you want more than one file type, as we do in the above example, each set of information are also separated with a pipe character. Setting the initial directory The initial directory used by the OpenFileDialog is decided by Windows, but by using the InitialDirectory property, you can override it.
You will usually set this value to a user specified directory, the application directory or perhaps just to the directory last used. You can set it to a path in a string format, like this: NET framework can help you though, just use the Environment class and its members for dealing with special folders: MyDocuments ; In this case, I get the path for the My Documents folder, but have a look at the SpecialFolder enumeration - it contains values for a lot of interesting paths.
For a full list, please see this MSDN article. Multiple files If your application supports multiple open files, or you simply want to use the OpenFileDialog to select more than one file at a time, you need to enable the Multiselect property.
In the next example, we've done just that, and as a courtesy to you, dear reader, we've also applied all the techniques mentioned above, including filtering and setting the initial directory: MyDocuments ; if openFileDialog. Once accepted, this example simply adds the filenames to the ListBox control, by looping through the FileNames property.
Please be aware that to reduce the amount of code lines, no exception handling is done in these examples. When working with files and doing IO tasks in general, you should always look out for exceptions, as they can easily occur due to a locked file, non-existing path or related problems.

To include special characters inside XML files you must use the numeric character reference instead of that character. The numeric character reference must be UTF-8 because the supported encoding for XML files is defined in the prolog as encoding="UTF-8" and should not be changed.
