I feel like I'm missing something obvious here...
I've got a text file in my WPF application which is located in a subfolder, so apologies for advance for the terrible ASCII.
+Project
+--+Subfolder
| +--TextFile.txt
|
+--App.config
+--App.xaml
+--etc.
The build action on this text file is Resource and I'm trying access the content as a string in my program, but I have absolutely no idea what I'm doing.
Trying to access the file through Properties.Settings.Default doesn't work, apparently there's only a ConnectionString resource in my program.
I can't do it in XAML because for whatever reason there's no Source property
<!-- somewhere up the top of App.xaml... -->
xmlns:clr="clr-namespace:System;assembly=mscorlib"
<clr:String Source="pack://application:,,,/Subfolder/Textfile.txt"/>
The FindResource method can't find it either.
FindResource("Usage.txt"); //ResourceReferenceKeyNotFoundException
All I'm trying to do is reference the text file, read it as a string and use that string. Otherwise I have to embed a 50 line verbatim string in the method call. Because that's totally a good idea. /s
In WinForms it was as simple as: Properties.Settings.Default.TextFile.ToString(); but nothing seems to work here.
I should point as well that this file shouldn't be included in the output directory, it needs to be embedded in the application or whatever the term is.
How should I be doing this?
This should work:
var uri = new Uri("pack://application:,,,/Subfolder/TextFile.txt");
var resourceStream = Application.GetResourceStream(uri);
using (var reader = new StreamReader(resourceStream.Stream))
{
var text = reader.ReadToEnd();
...
}
Try that:
using (StreamReader sr = new StreamReader(System.AppDomain.CurrentDomain.BaseDirectory + "/Subfolder/TextFile.txt"))
{
String line = sr.ReadToEnd();
Console.WriteLine(line);
}
You can do like this:
string file = #"pack://application:,,,/" + System.Reflection.Assembly.GetExecutingAssembly().GetName().Name + ";component/Subfolder/TextFile.txt";
using (var sr = new StreamReader(System.Windows.Application.GetResourceStream(new Uri(file)).Stream))
{
var data= sr.ReadToEnd();
}
For example, this is your project structure
+ProjectName
+--+imagesFolder
| +--amogus.png
|
+--App.xaml
+--MainWindow.xaml
+--etc.
and you want to access the to amogus.png in your xaml window,
You have two ways:
note this way the imagesFolder will be visible in the release build to users
to set amogus.png Build Action to Content and
Copy to Output Directory to Copy always more info,
then rebuild from the build menu, then add this to the window xaml
<Image Source="pack://siteoforigin:,,/imagesFolder/amogus.png" ></Image>
note this way the imagesFolder will be not visible in the release build to users
to set amogus.png Build Action to Resource and
Copy to Output Directory to Do not copy or blank more info,
then rebuild from the build menu, then add this to the window xaml
<Image Source="/imagesFolder/amogus.png" ></Image>

firstly apology if this has already been answered and I am duplicating the question. I have tried to find the answer to my issue but have failed and none of the auto-suggestions answers my problem.
I have my main project (XAML) and also a class library project called FileStore for files. The class library project is referenced into the main project and I have images and icon file in the class library project that I can access with no issues in my main project, however, I struggle to get the content of a txt file from the CL project to display in a label on the main project. I get the error: the system could not find the file and from the error, I can see that it is trying to look for a file in the main project bin\debug folder
I tried to follow this previous post which seemed to partly answer my issue but to no avail sadly.
Get relative file path in a class library project that is being referenced by a web project
The txt file Build action is set to: Resource and Copy to Output Directory set to: Copy Always.
As I mentioned I have the FileStore project referenced in my main project and the images work fine.
Below is the code I am using, I have tried different variations such as:
\Resources\textFile.txt and \textFile.txt, still no luck.
'''
public static string ReadFileinClLibr()
{
var buildDir =
Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);
var filePath = buildDir + #"\textFile.txt";
return File.ReadAllText(filePath);
}
'''
For comparition here is the path for the image files that works, but I cannot get it to work with the txt file, as the error reads: the given paths format is not supported..
'''
#"pack://application:,,,/FileStore;component/Resources\textFile.txt"
'''
I want to be able to input the content of the text file from the class library project to the label in the main xaml project.
At the moment compiler keeps looking for this file in a debug folder of the main project, what I want is, for the compiler to look for the txt file in a CL FileStore project
In order to access the file all the time, we have to have the file copied to the debug folder. Right click the file from solution explorer change the properties then try to access the file from the executing assembly location.
StringBuilder bodyContent = new StringBuilder();
string fileName = "myfile.txt";
try
{
string filePath = Path.Combine(Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location), fileName);
using (StreamReader sr = new StreamReader(filePath))
{
// Read the stream.
bodyContent.Append(sr.ReadToEnd());
}
}
catch(Exception ex)
{
Console.WriteLine(String.Format("{0} # {1}", "Exception while reading the file: " + ex.InnerException.Message, DateTime.Now));
throw ex;
}
Thanks to the post from #Sreekanth Gundlapally I have managed to fix my issues. I have mostly drawn on from the answer provided by #Sreekanth Gundlapally but there is one important bit missing. The string fileName should include any subfolders that the resource file is within in the Class Library Project, for example in my case the folder was named 'Resources' so the code should look like this:
string fileName = #"Resources/myfile.txt";
try
{
string filePath = Path.Combine(Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location), fileName);
using (StreamReader sr = new StreamReader(filePath))
{
// Read the stream.
bodyContent.Append(sr.ReadToEnd());
}
I have also cleaned and rebuilt solution after which it all worked a charm.
Also a side note, anyone trying this and getting funny characters make sure your file's encoding is set to UTF-8 as this is the default encoding used by StreamReader, otherwise your file content may not be read correctly if it contains signs such as apostrophe.
I'm attempting to do two things. I want to embed a text file into my project so that I can utilise it and modify it, but at the same time I don't want to have to package it when I send the project out to users (I.E included in the exe file).
I've had a look around and there's been multiple questions already but I just cant seem to get any to work. Here's the steps I've taken so far;
Added the text file to my "Resources Folder"
Build action to "Content" and output directory to "Do not copy"
I then try to access the file in my code;
if (File.Exists(Properties.Resources.company_map_template))
{
MessageBox.Show("Test");
var objReader = new StreamReader(Properties.Resources.company_map_template);
string line = "";
line = objReader.ReadToEnd();
objReader.Close();
line = line.Replace("[latlong]", latitude + ", " + longitude);
mapWebBrowser.NavigateToString(line);
}
The MessageBox never appears which to me means that it cannot find the file and somewhere somehow I've done something wrong. How can I add the file into my project so I don't need to distribute with an exe whilst being able to access it in code?
I would use the following:
BuildAction to None (not needed)
and add your file to Resources.resx under files (using DragAndDrop from SolutionExplorer to opened Resources.resx)
Access to your Text:
using YOURNAMESPACE.Configuration.Properties;
string fileContent = Resources.company_map_template;
Then you're done. You don't need to access through StreamReader
I want to put several template files on a directory named "Templates", relative to the executable of my application, and use them. One template file, for instance, is named "Globals.st".
That way, I created a TemplateGroupDirectory and loaded the template:
var group = new TemplateGroupDirectory("Templates");
var tmpl = group.GetInstanceOf("Globals");
On trying to get the instance of the template I've got a message saying that occurs a NullReferenceException.
What am I missing?
might be a syntax thing
heres an example:
string fullpath = Path.GetFullPath("templates/");
TemplateGroupDirectory tgd = new TemplateGroupDirectory(fullpath ,'<','>');
Template t = tgd.GetInstanceOf("helloworld");
t.Add("world", "shitty world");
i have a folder to named templates, with the file helloworld.st that contains
helloworld(world) ::= <<
hello, <world>
>>
My best guess is that it cannot find the .st file you need, remember to put copy on newer or always coby, on the .st files' properties, when you use relative paths, or else template will be nothing.
I've found several posts across stackoverflow and the rest of the internet regarding how to load Xaml from a static file: they recommend creating a XmlReader or StreamReader pointing to a file found on the file system, but the .xaml document I would like to read from is going to be compiled with the rest of the assembly, so it won't have a meaningful file Uri. I do not want to copy this document around wherever the assembly goes. Is there a way to read from a .xaml document that has been compiled into the assembly?
I also know that I can simply read from a very long string literal inside the code itself, but I'd rather not do that - the UIElement produced from the Xaml should be easily edited, and I gain this by editing it in a Xaml file.
To illustrate what I'm hoping for, here's an example:
private void LoadUIElementFromCompiledXaml()
{
XmlReader xmlReader = new XmlReader("*Uri for .xaml document within my assembly*");
UIElement elementLoaded = (UIElement)XamlReader.Load(xmlReader);
}
I apologize in advance if the answer is blatantly obvious.
Before you can load Xaml from an assembly as an embedded resource, there is a bit of setup you must do. I'll walk you through an example, then from there you can customize it to suite your needs.
Create folder in your project. Name it XAML.
Add a XAML file to the XAML folder. Lets call it Sample.xaml.
Right-click on Sample.Xaml and choose properties. Set the value for Build Action to "Embedded Resource".
Right-click on the project and choose properties. Take note of the Default namespace value. We will use this as part of the path. For this example lets assume it is "MyNamespace.
Your code to load the Xaml resource would look something like this:
string defaultNamespace = "MyNamespace";
string folderName = "XAML";
string fileName = "Sample.xaml";
string path = String.Format("{0}.{1}.{2}", defaultNamespace, folderName, fileName);
using (Stream stream = System.Reflection.Assembly.GetExecutingAssembly().GetManifestResourceStream(path))
{
object root = XamlReader.Load(stream);
}
As you can see the path to the resource is made up of the default namespace of the project, the folder path to the file, and the file name. If the folder path has multiple levels use dots as folder separator in place of back slashes. For example Xaml\Subfolder would be Xaml.Subfolder.
I want to load a xml document Swedish.xml which exists in my solution. How can i give path for that file in Xamarin.android
I am using following code:
var text = File.ReadAllText("Languages/Swedish.txt");
Console.WriteLine("text: "+text);
But i am getting Exception message:
Could not find a part of the path "//Languages/swedish.txt".
I even tried following lines:
var text = File.ReadAllText("./Languages/Swedish.txt");
var text = File.ReadAllText("./MyProject/Languages/Swedish.txt");
var text = File.ReadAllText("MyProject/Languages/Swedish.txt");
But none of them worked. Same exception message is appearing. Build Action is also set as Content. Whats wrong with the path? Thanks in advance.
Just try with this
string startupPath = Path.Combine(Directory.GetParent(System.IO.Directory.GetCurrentDirectory()).Parent.Parent.FullName, "Languages", "Swedish.txt");
var text = File.ReadAllText(startupPath);
Try...
Environment.GetFolderPath (Environment.SpecialFolder.MyDocuments)+"/Languages/Swedish.txt"
If you mark a file as Content Type, it will be included in the app bundle with the path that you are using within your project file. You can inspect the IPA file (it's just a renamed zip) that is created to verify that this is happening.
var text = File.ReadAllText("Languages/Swedish.txt");
should work. The file path is relative to the root of your application. You need to be sure that you are using the exact same casing in your code that the actual file uses. In the simulator the casing will not matter, but on the device the file system is case sensitive, and mismatched casing will break the app.
I've looked into this before and never found any solution to access files in this way. All roads seem to indicate building them as "content" is a dead end. You can however place them in your "Assets" folder and use them this way. To do so switch the "Content" to "AndroidAsset".
After you have done this you can now access the file within your app by calling it via
var filename = "Sweedish.txt";
string data;
using
(var sr = new StreamReader(Context.Assets.Open(code)))
data = sr.ReadToEnd();
