I have a Windows Forms app. There is a text file in the same folder with the app.
I want to read this text file and write it in a rich text box. I tried several things but can't do it. What should I do?
Here is my solution explorer;
Here is my About.cs:
private void About_Load(object sender, EventArgs e)
{
this.FormBorderStyle = FormBorderStyle.FixedSingle;
this.MaximizeBox = false;
this.MinimizeBox = false;
aboutText.Enabled = false;
string appPath = Path.GetDirectoryName(Application.ExecutablePath);
aboutText.Text = File.ReadAllLines(appPath + "TOSandAbout.txt").ToString();
}
I can't read like this.
I don't have VS on me at the moment, so no screenshots and I can't be sure of names, but the problem is because Visual Studio builds the source into a different directory (it's usually bin/Debug/ or bin/Release/ or something like that). Each file in the source directory has a behavior during the build process and I believe the default for .txt is "Do Not Copy". Open the Properties dialog for the file (right click->Properties) and where it says "Build Action", make sure it says "None" and then under "Copy to Output Directory" choose "Copy if Newer". This will make sure that the text file is actually alongside the executable when you build it (Build Action: None just means that there is no processing to be done on that file).
When a program starts the "current directory" will (usually) be set to the location of the exe. In that case, you do not have to specify any path, simply use "TOSandAbout.txt" as the path.
If that doesn't work, it's because the file isn't there. If you add a text file to your solution, it will by default not be copied to the build directory. Right click the file and hit Properties, change Copy to Output Directory to either Copy always or Copy if newer and you'll be set.

I have a folder structure in the project as seen in the picture:
and I would like to have the SettingsManagementTest.mvconfig File to be directly in the Release/Debug folder. But it is always built into a subfolder called SettingsManagement.
Is this even possible or should think of another solution?
Call var currentDir = Directory.GetCurrentDirectory(); and you will land in your Debug folder. I recommend printing currentDir out once so you have a better understanding of what the method returns.
You can call var bin = Directory.GetParent(currentDir); to path into your bin folder.
You use var release = Path.Combine(bin, "Release"); to path into your Release folder.
To create your desired file in the Release folder you can call File.Create(Path.Combine(release, "SettingsManagementTest.mvconfig"));

I have a folder in my project named Export, I save files to that folder using this code :
document.Save(#"D:\workspace\folder1\Solution.Application.DataExporter\Export\mydocument.pdf");
But when others use this code, they complain that they don't have that path. How can I give path to my code so that it works everywhere? Thanks.
Option 1: Use the Environment.SpecialFolder to get the physical location of a special folder. See here for an overview of possible special folders.
For example, if you want to put the document in 'my documents' folder, then Environment.SpecialFolder.MyDocuments would give you the location to the my documents folder on the current machine.
Code:
var path = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);
This way you are sure you always have the correct and existing location. If needed, you can always first create an export folder into this special folder with Directory.CreateDirectory(), if it does not exist yet.
Option 2: Of course, you can always ask for a location to the user if you don't want to use a predefined one, by using the SaveFileDialog class, for example.
Create the folder 'Export' in MyDocuments, and then save the file to that directory. As many others have pointed out. You need to save to a directory, that the executing user has access rights to.
string documentFolder = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments), #"Export");
if (!Directory.Exists(documentFolder))
{
Directory.CreateDirectory(documentFolder);
}
document.Save(Path.Combine(documentFolder, "mydocument.pdf"));

I have an .exe application that opens another .exe application in a different folder, which then executes a .bat file to compile a .tex document.
If the initial .exe application is in a different file to the .tex document it can not find it, but if it is in the same folder it runs perfectly.
Any way I can solve this issue? I need to be able to run the initial .exe from a different folder.
If you are calling batch file using Process class, dont forget to set WorkingDirectory property, otherwise it will use your executable` location as default path.
var process = new System.Diagnostics.Process();
process.StartInfo.FileName = #"D:\Dir\Run.bat";
process.StartInfo.WorkingDirectory = #"D:\Dir";
process.Start();
If you use System.Diagnostics.Process.Start you can specify the folder in which to run the batch file.
System.Diagnosis.Process

I'm having an issue in saving an rtf file, I'm saving it in a subfolder in "MyDocuments" the strange this is that i also save a .bin file and some other stuff and it doesn't causes any exeption, i'am pc admin so why does it happen?
string docs = System.Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments) + "\\Monitor\\Immobili\\";`
richTextBox1.SaveFile(docs+code);
code is also another string
An UnauthorizedAccessException means one of 3 things:
The caller does not have the required permission.
Path is a directory.
Path specified a read-only file.
Check for last two reasons. I think you are not adding filename after path. Add breakpoints and check if richTextBox1.SaveFile(docs+code); is getting the complete path to the file instead of just folder path.

Hi
I am trying to read a plain text file named "test.txt" from my system but all the attempts
File.Exists(), StreamReder are not getting the file, that is not a new task for me but i am irritated due to this strange behavior. I have given full permissions to the file but in vain. I am doing the test in a C# console application. The system has a fresh installation and I am wondering of any permission issue when run in debug mode. I also copied the file to Debug folder but still same error. Can anyone please guide me about this? Thanks in advance
There is a neat function in C# for reading string files: (in System.IO namespace)
string text = File.ReadAllText("test.txt");
If you are having trouble with the path, you can add test.txt as a resource with copy to (add the file to teh project, right-click properties and select Copy to output directory.
Then you can use:
string path = Path.Combine(Directory.GetCurrentDirectory(), "test.txt");
File.ReadAllText(path);
Have you stepped through the code? The first step is to make sure the path being used in the program is correct.
Debug mode will still run under your account so, if you have permission to open the file, that won't be a problem.
