I am using Path.GetTempPath function to get temp file path to store xml file at temporary location. At first this works successfully but for next run this gives a exception as "Illegal characters in file path".
string filepath = System.IO.Path.GetTempPath();
if (Interface.IsDebugMode)
{
xmlRepository.SaveDataToFile(filepath + #"\\savedFile.xml", true);
}
This should not work at all
xmlRepository.SaveDataToFile(filepath + #"\\savedFile.xml", true);
it needs to be This
xmlRepository.SaveDataToFile(filepath + "\\savedFile.xml", true);
or this
xmlRepository.SaveDataToFile(filepath + #"\savedFile.xml", true);
but not both And as the comment below says you really should be using this
xmlRepository.SaveDataToFile(Path.Combine(filepath, "savedFile.xml"), true);

I want upload an image file to project's folder but I have an error in my catch:
Could not find a part of the path 'C:\project\uploads\logotipos\11111\'.
What am I do wrong? I want save that image uploaded by my client in that folder... that folder exists... ah if I put a breakpoint for folder_exists3 that shows me a true value!
My code is:
try
{
var fileName = dados.cod_cliente;
bool folder_exists = Directory.Exists(Server.MapPath("~/uploads"));
if(!folder_exists)
Directory.CreateDirectory(Server.MapPath("~/uploads"));
bool folder_exists2 = Directory.Exists(Server.MapPath("~/uploads/logo"));
if(!folder_exists2)
Directory.CreateDirectory(Server.MapPath("~/uploads/logo"));
bool folder_exists3 = Directory.Exists(Server.MapPath("~/uploads/logo/" + fileName));
if(!folder_exists3)
Directory.CreateDirectory(Server.MapPath("~/uploads/logo/"+fileName));
file.SaveAs(Server.MapPath("~/uploads/logo/" + fileName+"/"));
}
catch(Exception e)
{
}
Someone knows what I'm do wrong?
Thank you :)
Try this:
string targetFolder = HttpContext.Current.Server.MapPath("~/uploads/logo");
string targetPath = Path.Combine(targetFolder, yourFileName);
file.SaveAs(targetPath);
Your error is the following:
bool folder_exists3 = Directory.Exists(Server.MapPath("~/uploads/logo/" + fileName));
if(!folder_exists3)
Directory.CreateDirectory(Server.MapPath("~/uploads/logo/"+fileName));
You check if a directory exists, but you should check if the file exists:
File.Exists(....);
You need filename
file.SaveAs(Server.MapPath("~/uploads/logo/" + fileName+"/" + your_image_fillename));
Remove the last part of the path to save you have an extra "/"
It should be
file.SaveAs(Server.MapPath("~/uploads/logo/" + fileName);
Also you do not have a file extension set.
I have a sync software, which loads CSV files from "Incoming" folder, processes them and then moves them to the "Archive" folder.
Today, I saw the following error with this sync software:
[23/06/2014 00:06:04 AM] : Failed to move file from
D:\IBI_ORDER_IMPORTER_FTP_SERVER\Template3\Fifty &
Dean\Incoming\5A040K___d6f1ca45937b4ceb98d29d0db4601bf4.csv to
D:\IBI_ORDER_IMPORTER_FTP_SERVER\Template3\Fifty &
Dean\Archive\5A040K___d6f1ca45937b4ceb98d29d0db4601bf4.csv - Could not
find a part of the path.
Here's a snippet taken out of the sync software, where the file is processed and moved:
public static void ProcessSingleUserFile(Int32 TemplateId, String ImportedBy, String FilePath)
{
// Always Rename File To Avoid Conflict
string FileName = Path.GetFileNameWithoutExtension(FilePath);
String NewFilePath = FilePath.Replace(FileName, Utils.RandomString() + "___" + FileName);
File.Move(FilePath, NewFilePath);
FilePath = NewFilePath;
// Log
SyncUtils.ConsoleLog(String.Format("Processing [ {0} as {1} ] By [ {2} ] On Template [ #{3} ]",
FileName + ".csv",
Path.GetFileName(FilePath),
ImportedBy,
TemplateId));
// Init
List<OrderDraft> myOrderDrafts = new List<OrderDraft>();
// Parsed Based On Template Id
if (TemplateId == Settings.Default.Multi_Order_Template_Id)
{
// Try Parse File
myOrderDrafts = Utils.ParseMultiImportFile(TemplateId, ImportedBy, FilePath, true);
}
else
{
// Try Parse File
myOrderDrafts.Add(Utils.ParseImportFile(TemplateId, ImportedBy, FilePath, true));
}
// Process Orders
foreach (OrderDraft myOrderDraft in myOrderDrafts)
{
/* code snipped */
}
// Archive File
File.Move(FilePath, FilePath.Replace("Incoming", "Archive"));
}
Any idea what this error means? and how to circumvent it?
I wrote a cut down version of the above to test this in a controlled environment and I am not getting the error with this code:
static void Main(string[] args)
{
try
{
string baseDir = #"C:\Users\Administrator\Desktop\FTP_SERVER\Template3\Fifty & Dean\Incoming\";
string[] filePaths = Directory.GetFiles(baseDir, "*.csv");
foreach (string filePath in filePaths)
{
// do some work here ...
// move file
string newFilePath = filePath.Replace("Incoming", "Archive");
File.Move(filePath, newFilePath);
Console.WriteLine("File successfully moved");
}
}
catch (Exception ex)
{
Console.WriteLine("Error: " + ex.Message);
}
Console.ReadKey();
}
You need to include the checks to make sure that the paths exist at runtime and check the output, something very simple like:
if(!Directory.Exists(Path.GetDirectoryName(filePath)))
{
Console.WriteLine("filePath does not exist: " + filePath);
}
if(!Directory.Exists(Path.GetDirectoryName(newFilePath)))
{
Console.WriteLine("newFilePath does not exist: " + newFilePath);
}
File.Move(filePath, newFilePath);
The reason I am suggesting this method is due to a possibility that the paths momentarily become available or not under the multi-tasking OSs depending on a multitude of factors: network connectivity, permissions (pushed down by GPO at any time), firewall rules, AV exclusions getting blown away etc. Even running low on CPU or RAM may create issues. In short, you never know what exactly occurred when your code was running if you are only checking the paths availability after the fact.
Or if your issue is intermittent, you can try and catch the error and write information to some sort of a log similarly to below:
try
{
File.Move(filePath, newFilePath);
}
catch(Exception ex)
{
if(!Directory.Exists(Path.GetDirectoryName(filePath)))
{
Console.WriteLine("filePath does not exist: " + filePath);
}
if(!Directory.Exists(Path.GetDirectoryName(newFilePath)))
{
Console.WriteLine("newFilePath does not exist: " + newFilePath);
}
}
"Could not find a part of the path" exception could also thrown from File.Move if argument used was longer than MAX_PATH (260) in .NET Framework.
So I prepend the path I used with long path syntax before passing to File.Move and it worked.
// Prepend long file path support
if( !packageFile.StartsWith( #"\\?\" ) )
packageFile = #"\\?\" + packageFile;
See:
How to deal with files with a name longer than 259 characters?
I have this
Could not find a part of the path
happened to me when I
File.Move(mapfile_path , Path.Combine(newPath, mapFile));
. After some testing, I find out our server administrator has blocked any user application from writing to that directory in that [newPath]!
So, right click on that directory to observe the rights matrix on Security tab to see anything that would block you.
Another cause of DirectoryNotFoundException "could not find a part of the path" thrown by File.Move can be spaces at the end of the directory name. Consider the following code:
string destinationPath = "C:\\Folder1 "; //note the space on the end
string destinationFileNameAndPath = Path.Combine(destinationPath, "file.txt");
if (!Directory.Exists(destinationPath))
Directory.CreateDirectory(destinationPath);
File.Move(sourceFileNameAndPath, destinationFileNameAndPath);
You may expect this code to succeed, since it creates the destination directory if it doesn't already exist, but Directory.CreateDirectory seems to trim the extra space on the end of the directory name, whereas File.Move does not and gives the above exception.
In this circumstance, you can workaround this by trimming the extra space yourself, e.g. (depending on how you load your path variable, the below is obviously overkill for a hard-coded string)
string destinationPath = "C:\\Folder1 ".Trim();
I'm add a file in one controller and in another controller I want check if the file is exist. I' using File.Exist(file), but it's always false, even if the file exist...
I adding file, and image is added successful.
if ((image!= null & image.ContentLength > 0))
{
string name = event.EventId.ToString() + ".jpg";
var fileName = name;
var path = Path.Combine(Server.MapPath("~/App_Data/Plakaty"), fileName);
plakat.SaveAs(path);
}
I'm checking in another controller if this file exist:
string file = "~/App_Data/Plakaty/" + wyd.EventId.ToString() + ".jpg";
ViewBag.file_exist = System.IO.File.Exists(file); //always is false
And my View: (It's returning only "No file")
#if (ViewBag.file_exist == true)
{
<p>File exist</p>
}
else
{
<p>No file</p>
}
You need to do the Server.MapPath again when checking the file and do the forward slash.
string file = Server.MapPath("~") + #"\App_Data\Plakaty\"
+ wyd.EventId.ToString() + ".jpg";
ViewBag.file_exist = System.IO.File.Exists(file ); //always is false
You forgot to write Server.MapPath when checking if file exist
Have you checked permissions?
The Exists method returns false if any error occurs while trying to determine if the specified file exists. This can occur in situations that raise exceptions such as passing a file name with invalid characters or too many characters, a failing or missing disk, or if the caller does not have permission to read the file. See documentation
However most likely is what #Obama answered about the path being wrong as you didn't call Server.MapPath
What I am trying to do is to read in a file to a richTextBox automatically with the OnSelectedIndexChange method. There arent any errors, it just flat out doesnt work. Heres the code that I am working with
public void comboBox1_OnSelectedIndexChanged(object sender, EventArgs e)
{
string selectedPath = comboBox1.SelectedItem.ToString();
if (File.Exists(#"C:\\Mavro\\MavBridge\\" + selectedPath + "\\ " + "Comment" + ".txt"))
{
try
{
Thread.Sleep(0500);
System.IO.StreamReader textFile = new System.IO.StreamReader(#"C:\\Mavro\\MavBridge\\" + selectedPath + "\\ " + "Comment" + ".txt");
richTextBox1.Text = textFile.ReadToEnd();
textFile.Close();
}
catch
{
MessageBox.Show("Error: File cannot be opened!", "Error");
}
}
else
{
MessageBox.Show("No comment was found in this folder", "Alert");
}
}
Just for fun, lets have you try something. First, replace the following line:
if (File.Exists(#"C:\\Mavro\\MavBridge\\" + selectedPath + "\\ " + "Comment" + ".txt"))
with this:
if(File.Exists(string.Format("C:\\Mavro\\MavBridge\\{0}\\Comment.txt", selectedPath)))
It looks like you had an extra space ("\\ " + "Comment"), so I'm sure that's why it never hits this block of code. Also, anytime you have an object that needs to be closed/disposed, more often than not it implements IDisposable, meaning you should encapsulate the object within a using block:
Thread.Sleep(0500);
try
{
using(System.IO.StreamReader textFile = new System.IO.StreamReader(string.Format("C:\\Mavro\\MavBridge\\{0}\\Comment.txt", selectedPath)))
{
richTextBox1.Text = textFile.ReadToEnd();
}
}
catch
{
MessageBox.Show("Error: File cannot be opened!", "Error");
}
However, this can be simplified even further by bypassing the StreamReader entirely and using System.IO.File.ReadAllText instead:
richTextBox1.Text = System.IO.File.ReadAllText(string.Format("C:\\Mavro\\MavBridge\\{0}\\Comment.txt", selectedPath));
Well, one problem comes from the fact that you have:
#"C:\\Mavro\\MavBridge\\" + selectedPath + "\\ " + "Comment" + ".txt"
Since you are using a verbatim string (the # at the beginning), you do not need to put double slashes.
For the rest, make sure your file exists.
Later edit: also I am not sure if you copy/pasted in a rush or something like that, but did you actually put the catch block inside the try ?
1) What is the error you see?
2) Are you positive the file exists?
3) Are you positive the path created by your code is the path you are expecting?
4) Why are you sleeping the thread?
5) Why not just use File.ReadAllText?
6) File.Exists will return false if the code is running with permissions that do not have access to a file, even if the file does exist. Does the user your code is running as, have permissions?
true if the caller has the required permissions and path contains the
name of an existing file; otherwise, false. This method also returns
false if path is null, an invalid path, or a zero-length string. If
the caller does not have sufficient permissions to read the specified
file, no exception is thrown and the method returns false regardless
of the existence of path.
and
The Exists method returns false if any error occurs while trying to
determine if the specified file exists. This can occur in situations
that raise exceptions such as passing a file name with invalid
characters or too many characters, a failing or missing disk, or if
the caller does not have permission to read the file.
Get rid of # before each string. Your directory as it currently is uses actual double slashes instead of C:\Mavro\MavBridge. Use single slashes with \ or go with # at the beginning, but don't use both.
Also, I would strongly suggest using Path.Combine instead of concatenating pieces together like that.
Wondering how to best deal with a problem I am having with xsltransform. Long story short, everything works in my test environment, but it crashes when I run it on the server due to the filenames it tries to deal with, which are output from another program, over which I have no control.
For example. "4Copy (2) of Fed_Around_Six__TFVC020-12.mov.xml" a simple # would solve this, but it's actually running on a service, and this service gets all files of that type in the directory and processes them one by one.
string[] filepaths = Directory.GetFiles(path, Filetype);
I keep the file name variable in:
FileInfo f = new FileInfo(filepaths[i]);
But the method I use for the transform:
myXslTransform = new XslCompiledTransform();
myXslTransform.Transform(filename,OutputFileName);
Only accepts (String, String) and thus when it sees "4Copy (2) of Fed_Around_Six__TFVC020-12.mov.xml" it has a heart attack and cuts it off.
I was thinking save the original name, rename, remove whitespace, transform, and rename back. But I think there is a smarter way to handle it out there, just not sure where to look. Is there a way of telling C# to handle a variable as a literal? Or a different transform method that accepts these weird filenames with very bad naming conventions?
Any insight that helps would be great!
The error & exception message I recieve from the Eventvwr is

}
The default directory when running a service is something like "windows/system32" and this isn't the directory of the executable.
This is probably the reason the XML file isn't found.
