Setting Log file path in app.config - c#

I have one requirement that i have to place the log file in the same directory of solution. That is my solution is placed in [drive]\work\Project1\solution file. But i have to create my log file to [drive]\work\Project1\Log\log.log. How it can be set in app.config file.
please help me. thanks in advance...

If you assume the Visual Studio directory layout, then your program will be in [drive]\work\Project1\bin\Release\ (or possibly \Debug). And you want your log file to be in the directory [drive]\work\Project1\Log.
That directory is the same as [drive]\work\Project1\bin\Release\..\..\Log\
So, one way to do it would be to get the executing program's full path name, extract the directory, and append ....\Log. Like this:
using System.IO; // for Path class
using System.Windows.Forms; // for Application.ExecutablePath
...
string GetLogFilePath()
{
string ProgramPath = Path.GetDirectory(Application.ExecutablePath);
string LogPath = Path.Combine(ProgramPath, #"\..\..\Log\");
return LogPath;
}
If you don't want to include System.Windows.Forms, you can instead include System.Reflection and get the assembly's location with Assembly.GetExecutingAssembly().Location.

How to Get current date and create directory Everyday in C#?

get current date and make directory and second when directory is created, in that directory I have to store excel file and also save file as current date.
String Todaysdate = DateTime.Now.ToString("dd-MM-yyyy");
if (!Directory.Exists("C:\\Users\\Krupal\\Desktop\\" + Todaysdate))
{
Directory.CreateDirectory("C:\\Users\\Krupal\\Desktop\\" + Todaysdate);
}
This code have made directory with current date.
But when I want to store file in that directory, it generates the error:
Could not find a part of the path
'D:\WORK\RNSB\RNSB\bin\Debug\22-01-2020\22-01-2020.XLS
Belove path is store excel file that i have to store.
using (System.IO.StreamWriter file = new System.IO.StreamWriter(Todaysdate+"\\"+DateTime.Now.ToString("dd/MM/yyyy") +".XLS"))
Actually you are making the directory in a path then you are saving the .xls in another path.
You are making the directory using this path:
"C:\\Users\\Krupal\\Desktop\\" + Todaysdate
Then, here the path where you are trying to save the .xls:
Todaysdate+"\\"+DateTime.Now.ToString("dd/MM/yyyy") +".XLS"
The error shows the problem clearly, it could not fin this path:
D:\WORK\RNSB\RNSB\bin\Debug\22-01-2020\22-01-2020.XLS
While creating the .xls you are omitting the root path, so the process looks for the path 22-01-2020\22-01-2020.XLS in his working directory D:\WORK\RNSB\RNSB\bin\Debug.
You just need to align those paths: I sugget you to use relative paths, so here how you should fix your code:
String Todaysdate = DateTime.Now.ToString("dd-MM-yyyy");
if (!Directory.Exists(Todaysdate))
{
Directory.CreateDirectory(Todaysdate);
}
//then
using (System.IO.StreamWriter file = new System.IO.StreamWriter(Todaysdate+"\\"+DateTime.Now.ToString("dd/MM/yyyy") +".XLS"))
I presume you are running your WinForms application in Debug mode. This means that your current path is [your application path]\bin\Debug. If you look in file explorer, you will find that an executable has been created there. When using StreamWriter without an absolute file name, the file it tries to create is relative to the current execution path (in your case 'D:\WORK\RNSB\RNSB\bin\Debug'). StreamWriter will create a new file, if one does not exist, but it will not create a new folder, and you are passing it Todaysdate + "\\" which is effectively a new folder. Hence you are getting the error message.
To fix your problem, you need to provide the absolute path to your newly created directory thus:
using (System.IO.StreamWriter file = new System.IO.StreamWriter("C:\\Users\\Krupal\\Desktop\\" + Todaysdate+"\\"+DateTime.Now.ToString("dd/MM/yyyy") +".XLS"))
Winforms always expect directories inside Debug Folder, since it's EXE file is inside Debug and try to find it inside Debug folder.
In error it clearly shows that it is looking inside "Debug" folder.
Can you check whether File Exists in the mentioned folder created by you in C Drive.
// To Write File
System.IO.File.WriteAllLines(#"C:\Users\Public\TestFolder\WriteLines.txt", lines);

How to copy an image to application folder?

I already know how to browse for an image using open file dialog. So let's say we already got the path :
string imagePath = "Desktop/Images/SampleImage.jpg";
I want to copy that file, into my application folder :
string appFolderPath = "SampleApp/Images/";
How to copy the given image to the appFolderPath programmatically?
Thank you.
You could do something like this:
var path = Path.Combine(
System.AppDomain.CurrentDomain.BaseDirectory,
"Images",
fileName);
File.Copy(imagePath, path);
where fileName is the actual name of the file only (including the extension).
UPDATE: the Path.Combine method will cleanly combine strings into a well-formed path. For example, if one of the strings does have a backslash and the other doesn't it won't matter; they are combined appropriately.
The System.AppDomain.CurrentDomain.BaseDirectory, per MSDN, does the following:
Gets the base directory that the assembly resolver uses to probe for assemblies.
That's going to be the executable path you're running in; so the path in the end (and let's assume fileName is test.txt) would be:
{path_to_exe}\Images\test.txt
string path="Source imagepath";
File.Copy(System.AppDomain.CurrentDomain.BaseDirectory+"\\Images", path);
\ System.AppDomain.CurrentDomain.BaseDirectory is to provide path of the application folder

Write a text file to a sub-folder

I am trying to write out a text file to: C:\Test folder\output\, but without putting C:\ in.
i.e.
This is what I have at the moment, which currently works, but has the C:\ in the beginning.
StreamWriter sw = new StreamWriter(#"C:\Test folder\output\test.txt");
I really want to write the file to the output folder, but with out having to have C:\ in the front.
I have tried the following, but my program just hangs (doesn't write the file out):
(#"\\Test folder\output\test.txt");
(#".\Test folder\output\test.txt");
("//Test folder//output//test.txt");
("./Test folder//output//test.txt");
Is there anyway I could do this?
Thanks.
Thanks for helping guys.
A colleague of mine chipped in and helped as well, but #Kami helped a lot too.
It is now working when I have:
string path = string.Concat(Environment.CurrentDirectory, #"\Output\test.txt");
As he said: "The CurrentDirectory is where the program is run from.
I understand that you would want to write data to a specified folder. The first method is to specify the folder in code or through configuration.
If you need to write to specific drive or current drive you can do the following
string driveLetter = Path.GetPathRoot(Environment.CurrentDirectory);
string path = diveLetter + #"Test folder\output\test.txt";
StreamWriter sw = new StreamWriter(path);
If the directory needs to be relative to the current application directory, then user AppDomain.CurrentDomain.BaseDirectory to get the current directory and use ../ combination to navigate to the required folder.
You can use System.IO.Path.GetDirectoryName to get the directory of your running application and then you can add to this the rest of the path..
I don't get clearly what you want from this question , hope this get it..
A common technique is to make the directory relative to your exe's runtime directory, e.g., a sub-directory, like this:
string exeRuntimeDirectory =
System.IO.Path.GetDirectoryName(
System.Reflection.Assembly.GetExecutingAssembly().Location);
string subDirectory =
System.IO.Path.Combine(exeRuntimeDirectory, "Output");
if (!System.IO.Directory.Exists(subDirectory))
{
// Output directory does not exist, so create it.
System.IO.Directory.CreateDirectory(subDirectory);
}
This means wherever the exe is installed to, it will create an "Output" sub-directory, which it can then write files to.
It also has the advantage of keeping the exe and its output files together in one location, and not scattered all over the place.

Get File From an Assembly

I want to read a file path from the following structure
The Structure is like : AssemblyName -> MyFiles (Folder) -> Text.txt
Here I want to get the path of the Text.txt. Please help
I think what you're looking for is a file embedded in the assembly. Check out this question. The first answer explains how to set up an embedded file, as well as how to get it from code.
You can do
string assemblyPath = Assembly.GetExecutingAssembly().Location;
string assemblyDirectory = Path.GetDirectoryName(assemblyPath);
string textPath = Path.Combine(assemblyDirectory, "MyFiles", "Test.txt");
string text = File.ReadAllText(textPath);
...just to split it up some...but you could write it all in one line needless to say...
alternatively, if your Environment.CurrentDirectory is already set to the directory of your executing assembly's location, you could just do
File.ReadAllText(Path.Combine("MyFiles", "Text.txt"));
Jeff has covered how you get the path, wrt your comment on his answer is the file you want to open actually included in your project output?
Under the properties pane for the relevant file look at the Copy to Output Directory option - it generally defaults to Do not copy. You will want to set it to Copy Always or Copy if Newer if you want to include a file in the output directory with your compiled program.
As a general note you should always wrap any IO in an appropriate try catch block or use the static File.Exists(path) method to check whether a file exists

Can c# understand this kind of pathing for pointing a file?

..\..\..\ConnectionInterface\ConnectionInterface.vbproj
I mean the "..\"
Because I am reading up a .sln file as a text file to get all the projects in that solution and the problem is this projects inside where in different directories or level.
Here is an example
..\..\..\ConnectionInterface\ConnectionInterface.vbproj
..\States\Components\States.vbproj
any ideas how to get the actual paths of these projects?
Path.GetFullPath(#"..\..\..\ConnectionInterface\ConnectionInterface.vbproj");
This is relative to the current working directory, therefore if the relative reference is not based on the current working directory you will need to define that first.
You can use Path.Combine, but you'll need to know where it's relative to. Basically find the directory that contains the original .sln file (e.g. using Path.GetDirectoryName and Path.GetFullPath) and then use Path.Combine to combine the original directory with the relative file.
For example:
using System;
using System.IO;
using System.Linq;
using System.Xml.Linq;
class Test
{
static void Main()
{
string originalFile = "Test.cs";
string relative = #"..\Documents\Foo";
string originalAbsoluteFile = Path.GetFullPath(originalFile);
string originalDirectory = Path.GetDirectoryName(originalAbsoluteFile);
string combined = Path.Combine(originalDirectory, relative);
string combinedAbsolute = Path.GetFullPath(combined);
Console.WriteLine(combinedAbsolute);
}
}
The question isn't very clear, but if you mean does C# understand: C:\SomeDir\InnerDir1\ ..\InnerDir2 to resolve to C:\SomeDir\InnerDir2, then yes, it will work. Just append directory the solution file is in with the relative path, and you are done.
