.net – FlowDocument contents as text

flowdocumentnetwpfxaml

What is the best way to get back the XAML/XML value of a FlowDocument?

I noticed there isn't a .Value, .Text, .Caption, .ToXml(), etc…

UDPATE:
I'd like to be able to get access to it initially to serialize to disk or database. Treat it as its own document format. Later translating it to other formats would be nice.
Also been wondering:
Any equivalent to a hyperlink (opens in new browser window) in a FlowDocument? Any workaround?

In response to your first question, you can use the XamlWriter to get XAML as a string. For example:

XamlWriter.Save(flowDocument);

David Veeneman has a nice example of this in the FlowDocumentToXamlConverter implementation he created for his Bindable WPF RichTextBox.

His converter will also convert back from a string containing XAML to a FlowDocument, which should handle your persistence requirement.

On your second question, you can embed WPF's Hyperlink element in a FlowDocument. These StackOverflow questions have more details:

C# – Copy the entire contents of a directory in C#

Much easier

private static void CopyFilesRecursively(string sourcePath, string targetPath)
{
    //Now Create all of the directories
    foreach (string dirPath in Directory.GetDirectories(sourcePath, "*", SearchOption.AllDirectories))
    {
        Directory.CreateDirectory(dirPath.Replace(sourcePath, targetPath));
    }

    //Copy all the files & Replaces any files with the same name
    foreach (string newPath in Directory.GetFiles(sourcePath, "*.*",SearchOption.AllDirectories))
    {
        File.Copy(newPath, newPath.Replace(sourcePath, targetPath), true);

.net – How to read embedded resource text file

You can use the Assembly.GetManifestResourceStream Method:

Add the following usings

using System.IO;
using System.Reflection;

Set property of relevant file:
Parameter Build Action with value Embedded Resource
Use the following code
```
var assembly = Assembly.GetExecutingAssembly();
var resourceName = "MyCompany.MyProduct.MyFile.txt";

using (Stream stream = assembly.GetManifestResourceStream(resourceName))
using (StreamReader reader = new StreamReader(stream))
{
    string result = reader.ReadToEnd();
}
```
resourceName is the name of one of the resources embedded in assembly. For example, if you embed a text file named "MyFile.txt" that is placed in the root of a project with default namespace "MyCompany.MyProduct", then resourceName is "MyCompany.MyProduct.MyFile.txt". You can get a list of all resources in an assembly using the Assembly.GetManifestResourceNames Method.

A no brainer astute to get the resourceName from the file name only (by pass the namespace stuff):

string resourceName = assembly.GetManifestResourceNames()
  .Single(str => str.EndsWith("YourFileName.txt"));

A complete example:

public string ReadResource(string name)
{
    // Determine path
    var assembly = Assembly.GetExecutingAssembly();
    string resourcePath = name;
    // Format: "{Namespace}.{Folder}.{filename}.{Extension}"
    if (!name.StartsWith(nameof(SignificantDrawerCompiler)))
    {
        resourcePath = assembly.GetManifestResourceNames()
            .Single(str => str.EndsWith(name));
    }

    using (Stream stream = assembly.GetManifestResourceStream(resourcePath))
    using (StreamReader reader = new StreamReader(stream))
    {
        return reader.ReadToEnd();
    }
}
