In my Windows application, I have a PictureBox and a Button control. I want to load an Image file from user from the button's OnClick event and save that image file in a folder name "proImg" which is in my project. Then I want to show that image in the PictureBox.
I have written this code, but it is not working:
OpenFileDialog opFile = new OpenFileDialog();
opFile.Title = "Select a Image";
opFile.Filter = "jpg files (*.jpg)|*.jpg|All files (*.*)|*.*";
if (opFile.ShowDialog() == DialogResult.OK)
{
try
{
string iName = opFile.FileName;
string filepath = "~/images/" + opFile.FileName;
File.Copy(iName,Path.Combine("~\\ProImages\\", Path.GetFileName(iName)));
picProduct.Image = new Bitmap(opFile.OpenFile());
}
catch (Exception exp)
{
MessageBox.Show("Unable to open file " + exp.Message);
}
}
else
{
opFile.Dispose();
}
It's not able to save the image in the "proImg" folder.
Actually the string iName = opFile.FileName; is not giving you the full path. You must use the SafeFileName instead. I assumed that you want your folder on your exe directory also. Please refer to my modifications:
OpenFileDialog opFile = new OpenFileDialog();
opFile.Title = "Select a Image";
opFile.Filter = "jpg files (*.jpg)|*.jpg|All files (*.*)|*.*";
string appPath = Path.GetDirectoryName(Application.ExecutablePath) + #"\ProImages\"; // <---
if (Directory.Exists(appPath) == false) // <---
{ // <---
Directory.CreateDirectory(appPath); // <---
} // <---
if (opFile.ShowDialog() == DialogResult.OK)
{
try
{
string iName = opFile.SafeFileName; // <---
string filepath = opFile.FileName; // <---
File.Copy(filepath, appPath + iName); // <---
picProduct.Image = new Bitmap(opFile.OpenFile());
}
catch (Exception exp)
{
MessageBox.Show("Unable to open file " + exp.Message);
}
}
else
{
opFile.Dispose();
}
You should provide a correct destination Path to File.Copy method. "~\ProImages..." is not a correct path. This example will copy selected picture to folder ProImages inside the project's bin folder :
string iName = opFile.FileName;
File.Copy(iName, Path.Combine(#"ProImages\", Path.GetFileName(iName)));
the path is relative to current executable file's location, except you provide full path (i.e. #"D:\ProImages").
In case you didn't create the folder manually and want the program generate ProImages folder if it doesn't exist yet :
string iName = opFile.FileName;
string folder = #"ProImages\";
var path = Path.Combine(folder, Path.GetFileName(iName))
if (!Directory.Exists(folder))
{
Directory.CreateDirectory(folder);
}
File.Copy(iName, path);
PS: Notice the use of verbatim (#) to automatically escape backslash (\) characters in string. It is common practice to use verbatim when declaring string that represent path.
Try using picturebox.Image.Save function. In my program it is working
PictureBox.Image.Save(Your directory, ImageFormat.Jpeg)
example
pictureBox2.Image.Save(#"D:/CameraImge/"+foldername+"/"+ numbering + ".jpg", ImageFormat.Jpeg);
You write code like this.
string appPath = Path.GetDirectoryName(Application.ExecutablePath) +foldername ;
pictureBox1.Image.Save(appPath + #"\" + filename + ".jpg", ImageFormat.Jpeg);

I am writing a c# desktop app where I want users to select a file from open file dialog after which the program will copy the file to where the application is executing from: here is my code that is not working at the moment
var dlg = new Microsoft.Win32.OpenFileDialog {
Title = "Select File",
DefaultExt = ".json",
Filter = "Json File (.json)|*.json",
CheckFileExists = true
};
if (dlg.ShowDialog() == true)
{
try
{
var currentDirectory = System.Windows.Forms.Application.ExecutablePath;
var destFile = Path.Combine(currentDirectory + "/temp/", dlg.FileName);
File.Copy(dlg.FileName, destFile, true);
}
catch (Exception ex)
{
MessageBox.Show(string.Format("An error occured: " + ex.Message));
}
}
Now I am getting the error that
the file is being used by another program
. When I edit the code that is meant to initiate the copy by removing true:
File.Copy(dlg.FileName, destFile);
I get the error that the
file already exists
in the directory where it is being selected from.
It seems, that you have an incorrect path to write into.
System.Windows.Forms.Application.ExecutablePath
returns exe file itself, not directory. Try
var destFile = Path.Combine(
Path.GetDirectoryName(Application.ExecutablePath), // Exe directory
"temp", // + Temp subdirectory
Path.GetFileName(dlg.FileName)); // dlg.FileName (without directory)
If you aren't sure that temp exists, you have to create it:
Directory.CreateDirectory(Path.GetDirectoryName(destFile));
Use below Code for Copy file from one folder to another folder.
string[] filePaths = Directory.GetFiles("Your Path");
foreach (var filename in filePaths)
{
string file = filename.ToString();
//Do your job with "file"
string str = "Your Destination"+file.ToString(),Replace("Your Path");
if (!File.Exists(str))
{
File.Copy(file , str);
}
}
I am trying to move all files from rootFolderPath to destinationPath
try
{
string rootFolderPath = #"D:\Log_siteq\";
if (!Directory.Exists(Path.Combine(#"D:\Log_takaya\" + comboBox1.SelectedItem.ToString())))
{
System.IO.Directory.CreateDirectory(Path.Combine(#"D:\Log_takaya\" + comboBox1.SelectedItem.ToString()));
}
string destinationPath = Path.Combine(#"D:\Log_takaya\" + comboBox1.SelectedItem.ToString() );
string fileTypes = #"*.*";
string[] fileList = System.IO.Directory.GetFiles(rootFolderPath, fileTypes);
foreach (string file in fileList)
{
string ext = Path.GetExtension(file);
string destination = Path.Combine(destinationPath,file);
File.Move( file,destination);
MessageBox.Show(file);
MessageBox.Show(destination);
}
}
catch(Exception ex)
{
MessageBox.Show(ex.ToString());
}
Apparently MessageBox.Show(file); shows me my root folder path ( as is normal) but MessageBox.Show(destination); is showing me the same thing.
What gives? It just moves my file from my root folder in the same folder.Am I not getting something?
You are combining the destinationPath with the complete file path of file:
string destination = Path.Combine(destinationPath, file);
which will just overwrite the destination with the original file path (because "C:\desitnation\C:\source\filename.txt" isn't a valid path).
Instead, you need only the file name like this:
string destination = Path.Combine(destinationPath, Path.GetFileName(file));
What I have here is the user select a folder full of .txt files from a external drive and a dummy file is made with the filename to a local folder.
I have 2 questions regarding the code below.
How do I verify that the user select a specific folder?
How do I remove the .txt extension? The code copies the file name and creates the files but its labeled "text.txt.png" but I need it to read "text.png".
int g;
private void folderSelect()
{
FolderBrowserDialog folder = new FolderBrowserDialog();
folder.RootFolder = Environment.SpecialFolder.MyComputer;
folder.ShowNewFolderButton = false;
folder.Description = "Select Folder";
if (folder.ShowDialog() == DialogResult.OK)
{
DirectoryInfo files = new DirectoryInfo(folder.SelectedPath);
FileInfo[] textFiles = files.GetFiles("*.txt");
while (g < textFiles.Length)
{
if (g <= textFiles.Length)
{
File.Create("path/" + (textFiles[g].Name + ".png"));
g++;
}
else
{
break;
}
}
}
Note: I tried using Path.GetFileNameWithoutExtension to remove the extension but Im not sure if i was using it correctly.
Any help would be appreciated. Thank you in advance.
const string NEW_PATH = "path/";
if (!Directory.Exists(NEW_PATH))
Directory.CreateDirectory(NEW_PATH);
const string PATH_TO_CHECK = "correctpath";
FolderBrowserDialog folder = new FolderBrowserDialog();
folder.RootFolder = Environment.SpecialFolder.MyComputer;
folder.ShowNewFolderButton = false;
folder.Description = "Select Folder";
if (folder.ShowDialog() == DialogResult.OK)
{
string pathPastDrive = folder.SelectedPath.Substring(Path.GetPathRoot(folder.SelectedPath).Length).ToLower();
// Here it depends on whether you want to check (1) that the path is EXACTLY what you want,
// or (2) whether the selected path just needs to END in the path that you want.
/*1*/ if (!pathPastDrive == PATH_TO_CHECK)
/*2*/ if (!pathPastDrive.EndsWith(PATH_TO_CHECK))
return; // or you can throw an exception if you want
foreach (string textFile in Directory.GetFiles(folder.SelectedPath, "*.txt"))
File.Create(NEW_PATH + Path.GetFileNameWithoutExtension(textFile) + ".png");
}
You can use GetFileNameWithoutExtension, and it makes it pretty easy.
Also, if you're already sure that your new folder exists, then you can elide the first three lines and replace NEW_PATH with "path/" in the last line.
To see the returned path just use the SelectedPath property, then you can compare it to whatever you had in mind. The # before the path just means I don't have to escape any characters, it's the same as "C:\\MyPath".
FolderBrowserDialog folder = new FolderBrowserDialog();
if (folder.ShowDialog() == DialogResult.OK)
{
if (folder.SelectedPath == #"C:\MyPath")
{
// DO SOMETHING
}
}
You already hit the nail on the head about the file name without extension, change this line:
File.Create("path/" + (textFiles[g].Name + ".png"));
To this:
File.Create("path/" + (Path.GetFileNameWithoutExtension(textFiles[g].Name) + ".png"));
Edit:
To get the folder name you already have the DirectoryInfo object so just use that:
DirectoryInfo files = new DirectoryInfo(folder.SelectedPath);
string folderName = files.Name;
I'm working on a project where I want a directory to be generated according to a textfield value and I want to copy a file into the created folder...So far I could able to create the directory and copy the file but into the created folder....
try
{
string id = textBox4.Text.Trim();
// Directory.CreateDirectory("C:\\Users\\prashan\\Desktop\\"+id);
string source = null;
OpenFileDialog ofd = new OpenFileDialog();
if (ofd.ShowDialog()==System.Windows.Forms.DialogResult.OK)
{
source = ofd.FileName;
MessageBox.Show(source);
}
string File_name = Path.GetFileName(source);
string destination = "C:\\Users\\prashan\\Desktop\\" +
System.IO.Directory.CreateDirectory(id) + File_name;
System.IO.File.Copy(source, destination);
MessageBox.Show("Done....");
}
catch (Exception ex)
{
MessageBox.Show(ex.StackTrace);
}
You have the following code:
string destination = "C:\\Users\\prashan\\Desktop\\"
+ System.IO.Directory.CreateDirectory(id) + File_name;
You are concatenating the result of CreateDirectory() into your destination filename, which is incorrect. Instead, you could split this into two operations, like this:
System.IO.Directory.CreateDirectory("C:\\Users\\prashan\\Desktop\\" + id);
string destination = "C:\\Users\\prashan\\Desktop\\" + id + "\\" + File_name;
This isn't the cleanest way to do this, using Path.Combine() would be better, but I wanted to change your code as little as possible.
Small change in your code. Destination path modified to make it valid path.
try
{
string id = textBox4.Text.Trim();
Directory.CreateDirectory("C:\\Users\\prashan\\Desktop\\"+id);
string source = null;
OpenFileDialog ofd = new OpenFileDialog();
if (ofd.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
source = ofd.FileName;
MessageBox.Show(source);
}
string File_name = Path.GetFileName(source);
string destination = "C:\\Users\\prashan\\Desktop\\" + id +"\\"+ File_name;
System.IO.File.Copy(source, destination);
MessageBox.Show("Done....");
}
catch (Exception ex)
{
MessageBox.Show(ex.StackTrace);
}
I'm writing a little utility that starts with selecting a file, and then I need to select a folder. I'd like to default the folder to where the selected file was.
OpenFileDialog.FileName returns the full path & filename - what I want is to obtain just the path portion (sans filename), so I can use that as the initial selected folder.
private System.Windows.Forms.OpenFileDialog ofd;
private System.Windows.Forms.FolderBrowserDialog fbd;
...
if (ofd.ShowDialog() == DialogResult.OK)
{
string sourceFile = ofd.FileName;
string sourceFolder = ???;
}
...
fbd.SelectedPath = sourceFolder; // set initial fbd.ShowDialog() folder
if (fbd.ShowDialog() == DialogResult.OK)
{
...
}
Are there any .NET methods to do this, or do I need to use regex, split, trim, etc??
Use the Path class from System.IO. It contains useful calls for manipulating file paths, including GetDirectoryName which does what you want, returning the directory portion of the file path.
Usage is simple.
string directoryPath = Path.GetDirectoryName(filePath);
how about this:
string fullPath = ofd.FileName;
string fileName = ofd.SafeFileName;
string path = fullPath.Replace(fileName, "");
if (openFileDialog1.ShowDialog(this) == DialogResult.OK)
{
strfilename = openFileDialog1.InitialDirectory + openFileDialog1.FileName;
}
You can use FolderBrowserDialog instead of FileDialog and get the path from the OK result.
FolderBrowserDialog browser = new FolderBrowserDialog();
string tempPath ="";
if (browser.ShowDialog() == DialogResult.OK)
{
tempPath = browser.SelectedPath; // prints path
}
Here's the simple way to do It !
string fullPath =openFileDialog1.FileName;
string directory;
directory = fullPath.Substring(0, fullPath.LastIndexOf('\\'));
This was all I needed for the full path to a file
#openFileDialog1.FileName
