I have C# windows application with XML file. After installing the set up file I need to edit the XML file time to time. But my XML file not going to the path where the executable is located.
So that is giving error.
With in a program I'm getting XML path like this.
private string PATH = Path.Combine(Application.StartupPath, "XMLFile1.xml");
Please some one can suggest a way to do.
If you have installed your application on Windows Vista, 7, or 8, it's quite possible that you get security exceptions. Since you haven't told what kind of errors you get I have to ask my crystal ball to think with me.
He thinks that because you are trying to write in a protected folder you get an exception.
He suggest you move the XML to %appdata% or %localappdata%
Use Application.ExecutablePath, the Application.StartupPath property will change if your app is started from desktop shortcut or any other shortcuts.
private string PATH = Path.Combine(Path.GetDirectoryName(Application.ExecutablePath), "XMLFile1.xml");
You have to include it in project. Here's a helpful link: How to include XML file while creating setup file for windows application
while your application starts copy your XML file to a common folder path, if it is not exist in the path. Do your edit on the xml file in the common folder.
better to use common folder as Local application Data Folder
Path.Combine(Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData), "Your application name")

I am creating an application in WPF.
In that I am using XML file to store some settings.
My app will run for every 10 sec. So it will use that XML file settings.
My issue is in My local system i am calling the XML file as D://Foldername/projectname/test.xml .
But after deployment it is storing in C://Programfiles/Projectname/test.xml .
So how to give a generic path so that it runs in all the client systems.
I am creating setup file to install in clients systems.
Please help me.
Open the project properties page.
Click on Settings tab.
Add a new item called "MyPath". Make it an Application Setting of type String and give it a sensible default path name as value.
Reference the value in code with Properties.Settings.Default.MyPath.
If you open the applications config there will be a setting called MyPath where you can override the path at runtime.
I suggest you to put the XML file in the same folder as your EXE file and then use Assembly to get its current path.
var cfgPath = Assembly.GetExecutingAssembly().Location + ".config"
Update
it's better to name your config file the same with your exe file but with ".config" extension.
If you are really using ClickOnce, I hardly recommend you to create your own directory for data and configuration files:
private static string GetDataDir()
{
var dataDir = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData),
"YourApplicationName");
if (!Directory.Exists(dataDir))
Directory.CreateDirectory(dataDir);
return dataDir;
}
The problem with storing the data in the directory of the executable is, that it will be at a different location. While debugging, it will be in you \bin directory. When the application is deployed by ClickOnce, you gonna have a bad time. The installation directory for a ClickOnce application is created for every version. So if you EVER update your application at "customers", all their settings will be lost.
XmlReader reader = XmlReader.Create(#"E:\NewFolder\WindowsFormsApplication1\WindowsFormsApplication1\QuestionFile.xml")
In my application i have read a xml file which is location in a specific location in my pc but now i want to deploy my application now when i rum my exe and install in other pc i get error that read error of xml file so what should i do for that.
like that i have used to read the xml file.
I would really appreciate if someone helps me out!
thanks
You could include the XML in the same folder as your program. In the code, build up the string dynamically, using the following to get the name of the folder the program is currently executing from:
Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);
All you need to do after that is append the name of your XML file with Path.Combine or appending to the string.
Edit:
(You'll need to include references to System.IO and System.Reflection).
You could create the string holding the path separately, then use that for creating your reader:
string xmlLocation = Path.Combine(Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location), "QuestionFile.xml");
XmlReader reader = XmlReader.Create(xmlLocation);
Remember if you're running this in debug in VS, this will point to your debug directory so make sure a copy of the XML file is in there.
Can you package the questions.xml with the EXE as embedded resource?
Well, I think you have two options:
1) include the xml inside your solution as an embedded resource, and read it using GetManifestResourceStream. Here's more info on how to do it.
2) Include it in the solution and set the file's Build Action to Content. Then in your MSI installer package you can include that project's "Content" output. This means the file will end up included as a separate physical file located in the application's installation path.
See Here for more details. Step 2 shows how to add different outputs.
Ladies and Gentlemen , I have been stuck with this for a few hours and do not find an answer. I have a Setup project in Visual Studio that creates an installer for my C# application. What I want is to add a folder with an XML file from which my application can read and write to the User's Application Data folder. In the File System Editor window I added the User's Application Data folder. In this folder I added a new folder (renaming it to my app's name) and then place the XML file in there. I also set the AlwaysCreate to true for the folder. The installer should create the folder in C:\Users\UserName\AppData\Local and add the file to it. However, the installer does not create the folder or the XML file my application uses. What am I missing? Is there another way to install a read/write XML file? Thanks in advance!
Ok, I found what the issue was. If a file is added to the User's Application Data folder it is installed on the target computer at C:\Users\Username\AppData\Roaming and not into AppData\Local.
Therefore, I changed my application get the file from Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData) instead of Environment.GetFolderPath( Environment.SpecialFolder.LocalApplicationData).
Hope it helps someone else...
I write a win app,now i want to make setup for my app project.i have a folder in the
root path of my project and it contains some wave files that i use theire path
in my app like: "F:\test\Resources\1.wav".
now my queistion is: how can i use their path in correct format ,that if i install setup file,on
another computer my app works true ,only because of the path of the wave files.
thanks alot for your attention.
You can get your EXE's path by calling System.Reflection.Assembly.GetExecutingAssembly().Location.
Alternatively you could store you install path in the registry somewhere with the installer and then you can check that registry entry.
You can useApplication.StartupPath, and append your subfolder.
So something like Application.StartupPath + #"\Resources\1.wav" should do the trick.
This is without Reflection, so I guess it will be a little faster, but I haven't benchmarked it.
I have an application that contains a sub folder that contain xml file ,that is use as a database now i want take the path of the xml file at run time ,how can i achieve this in window application?
I know how it does in asp.net using Server.MapPath but i want this is same in windows application
please help
thanks in advance .
Use Aplication.ExecutablePath property when am XML document and executable are reside in the same directory.
I think the recommended way in Windows is to use the Application.StartupPath property.
And with Path.Combine you can have your xml file path Server.MapPath-style like this:
var appPath = Application.StartupPath;
var xmlPath = Path.Combine(appPath, "data/my_db.xml");
// xmlPath now points to app-relative data/my_db.xml file
...
A nuanced answer:
The best way to access data would be to put it in Application.CommonAppDataPath or Application.UserAppDataPath so that it does not depend on the application's installed path. However, there are many reasons why you might need to avoid this.
To answer your question:
If the application is a standard forms application deployed to the client's machine by an installer or XCopy deployment, then the path to the executable is Application.ExecutablePath
If the application is Click-Once deployed, then I would not recommend using the above since the app's path is obscured, shadow-copied and put in the sandbox. You can use ApplicationDeployment.IsNetworkDeployed to test for click-once deployment then ApplicationDeployment.CurrentDeployment.ActivationUri to get the URI that the application was launched from. Your app-relative file will be on that web server; you will always be able to download it.
of course in click-once deployent it would be better to tag the file as Data in which case it would be accessible through ApplicationDeployment.CurrentDeployment.DataDirectory
if the application is a web app, then the Application class is useless. In this case you should use Assembly.GetExecutingAssembly().Location This works because currently executing assembly for a web app is almost always in the web app's /bin directory.
For a "portable" assembly where you don't have an installer, and for rare cases where you don't want to use the Application class, use Assembly.GetEntryAssembly().Location This works because it figures out what the entry point assembly is (your application) and uses that location. This is reliable because assemblies that your entry assembly load don't have to be in the same directory as the entry assembly.
You can get the directory of the currently executing assembly using
System.Runtime.Reflection.Assembly.GetExecutingAssembly().Location
from there you can get to your subdirectory.
