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.

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 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 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'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.

I am getting the following error on a project of mine when I try to build... Error CS2001: Source file '.cs' could not be found. I took the two files that are causing this error out on purpose because they conflict with other files and cannot be in there. How can I resolve this error without putting the 2 files back in the solution?
They are likely still referenced by the project file. Make sure they are deleted using the Solution Explorer in Visual Studio - it should show them as being missing (with an exclamation mark).
I open the project,.csproj, using a notepad and delete that missing file reference.
I had this problem, too.
Possible causes in my case: I had deleted a duplicated view twice and a view model.
I reverted one of the deletes and then the InitializeComponent error appeared.
I took these steps.
I checked all of the solutions mentioned on this question. The class
name and build action were correct.
I Cleaned my Solution and rebuilt. Another error appeared. "Error CS2001: Source file '.cs' could not be found"
I found this answer and followed the steps.
I reloaded the project and cleaned/rebuilt again.
My solution builds without errors and my application works now.
In my case, I add file as Link from another project and then rename file in source project that cause problem in destination project. I delete linked file in destination and add again with new name.
