So, I am trying to create a file at a specific path but the code I have doesn't allows me to create folders.
This is the code I have:
public void LogFiles()
{
string data = string.Format("LogCarga-{0:yyyy-MM-dd_hh-mm-ss}.txt", DateTime.Now);
for (int linhas = 0; linhas < dataGridView1.Rows.Count; linhas++)
{
if (dataGridView1.Rows[linhas].Cells[8].Value.ToString().Trim() != "M")
{
var pathWithEnv = #"%USERPROFILE%\AppData\Local\Cargas - Amostras\_logs\";
var filePath = Environment.ExpandEnvironmentVariables(pathWithEnv);
using (FileStream fs = new FileStream(filePath, FileMode.OpenOrCreate))
{
using (StreamWriter writer = File.AppendText(filePath + data))
{
string carga = dataGridView1.Rows[linhas].Cells[0].Value.ToString();
string referencia = dataGridView1.Rows[linhas].Cells[1].Value.ToString();
string quantidade = dataGridView1.Rows[linhas].Cells[2].Value.ToString();
string dataemissao = dataGridView1.Rows[linhas].Cells[3].Value.ToString();
string linha = dataGridView1.Rows[linhas].Cells[4].Value.ToString();
string marca = dataGridView1.Rows[linhas].Cells[5].Value.ToString().Trim();
string descricaoweb = dataGridView1.Rows[linhas].Cells[6].Value.ToString().Trim();
string codprod = dataGridView1.Rows[linhas].Cells[7].Value.ToString().Trim();
string tipoemb = dataGridView1.Rows[linhas].Cells[8].Value.ToString().Trim();
string nomepc = System.Environment.MachineName;
writer.WriteLine(carga + ", " + referencia + ", " + quantidade + ", " + dataemissao + ", " + linha + ", " + marca + ", " + descricaoweb + ", " + codprod + ", "
+ tipoemb + ", " + nomepc);
}
}
}
}
}
This %USERPROFILE%\AppData\Local\ in the universal path and I want to automatically create the \Cargas - Amostras\_logs\.
Do you have any idea how to do it?
The simpelest solution is replace
using (FileStream fs = new FileStream(filePath, FileMode.OpenOrCreate))
with
System.IO.Directory.CreateDirectory(filePath)
That will create the directory if it does not exist or do nothing if it does.
You need to create two checks, for your first folder and then second directory.
var pathWithEnv = #"%USERPROFILE%\AppData\Local\Cargas - Amostras\";
if (System.IO.Directory.Exists(pathWithEnv))
{
pathWithEnv = System.IO.Path.Combine(pathWithEnv, #"_logs\");
if (System.IO.Directory.Exists(pathWithEnv))
{
//Do what you want to do, both directories are found.
}
else
{
System.IO.Directory.CreateDirectory(pathWithEnv);
//Do what you want to do, both directories are available.
}
}
else
{
System.IO.Directory.CreateDirectory(pathWithEnv);
pathWithEnv = System.IO.Path.Combine(pathWithEnv, #"_logs\");
if (System.IO.Directory.Exists(pathWithEnv))
{
//Do what you want to do, both directories are available now.
}
else
{
System.IO.Directory.CreateDirectory(pathWithEnv);
//Do what you want to do, both directories are created.
}
}

Hello i'm developing a little application that download attachment from unread mails by imap and make a sevarla job on this attachment. Problem is encoding because after i have saved a, for example, txt file, when i load it again letters with accents becomes "?" I dont know why. I tried a several example around on the web (like converting directly the file from ansi to utf-8) with no result. Whe i open a file in windows it works, words are correct.
i have used either ReadAllText that StreamReader in the following example:
string contents = File.ReadAllText(AppDomain.CurrentDomain.BaseDirectory + "\\uid\\" + summary.UniqueId.ToString() + "\\" + fileName, Encoding.UTF8);
using (StreamReader reader = new StreamReader(contents, Encoding.UTF8))
as you can see in the following example if i set directly a string with an accent word, it works, from file no.
Please help me!

After searching around on the web i found a solution, here microsoft msdn
Streamreader and maybe readalltext doesn't support accent letters with UTF-8 Encoding, so changing it in UTF-7, letters are showed correctly.
Thank you for all support!
I have been trying to organize a code that it is a mess! The first and my biggest problem at this point is that one of my StreamWriters or StreamReader is being left open. Using this link, I am trying to organize my code. But my problem is that I am not sure where should I close it:
My code is:
public static void ProcessFile(string[] ProcessFile, int id_customer, string directoryinprocess)
{
StreamWriter Writer = null, Writer2 = null, Writer3 = null;
foreach (string filename in ProcessFile)
{
// Used for the output name of the file
var dir = Path.GetDirectoryName(filename);
var fileName = Path.GetFileNameWithoutExtension(filename);
var ext = Path.GetExtension(filename);
var folderbefore = Path.GetFullPath(Path.Combine(dir, #"..\"));
int rowCount = 0;
string path_body_out = "";
string outputname = folderbefore + "output_temp\\" + fileName;
if (filename.Contains("RO_"))
{
Writer = new StreamWriter(dir + "\\" + "output_temp\\" + fileName + "_hd_intermediate" + ext) { AutoFlush = true };
Writer2 = new StreamWriter(dir + "\\" + "output_temp\\" + fileName + "_body_out" + ext) { AutoFlush = true };
path_body_out = dir + "\\" + "output_temp\\" + fileName + "_hd_intermediate" + ext;
} // end of if
else
{
Writer3 = new StreamWriter(dir + "\\" + "output_temp\\" + fileName + "_out" + ext) { AutoFlush = true };
} // end of else
using (StreamReader Reader = new StreamReader(#filename))
{
while (!Reader.EndOfStream)
{
string inputLine = string.Empty;
inputLine = Reader.ReadLine();
rowCount++;
if (filename.Contains("RO_"))
{
if (rowCount <= 4)
{
Writer.WriteLine(inputLine);
}
if (rowCount >= 5)
{
Writer2.WriteLine(inputLine);
}
}
else
{
{ Writer3.WriteLine(inputLine); }
}
} // end of the while
} // end of using Stremreader
if (path_body_out.Contains("_hd_intermediate"))
{
ManipulateHeaderFilesTypeRo(dir, path_body_out);
}
else
{ }
} // end of the foreach
string[] extensions = { "_fv", "_body", "_out" };
string[] fileEntriesout = System.IO.Directory.EnumerateFiles(directoryinprocess, "*.csv", System.IO.SearchOption.AllDirectories)
.Where(file => extensions.Any(ex => Path.GetFileNameWithoutExtension(file).EndsWith(ex)))
.ToArray();
foreach (string filenameout in fileEntriesout)
{
string destinytablename = null;
if (filenameout.Contains("_hd_intermediate_fv"))
{ destinytablename = "TBL_DATA_TYPE_RO_HEADER"; }
else if (filenameout.Contains("_body_out"))
{ destinytablename = "TBL_DATA_TYPE_RO_BODY"; }
else
{ destinytablename = "TBL_DATA_TYPE_LOAD"; }
string id_file = Get_id_file(filenameout, id_customer);
DataTable csvFileData = GetDataTabletFromCSVFile(filenameout, id_file);
InsertDataIntoSQLServerUsingSQLBulkCopy(csvFileData, destinytablename);
} // end of the foreach
//} // end of the foreach
} // end of ProcessFile
Question:
How should I close the part:
if (filename.Contains("RO_"))
{
Writer = new StreamWriter(dir + "\\" + "output_temp\\" + fileName + "_hd_intermediate" + ext) { AutoFlush = true };
Writer2 = new StreamWriter(dir + "\\" + "output_temp\\" + fileName + "_body_out" + ext) { AutoFlush = true };
path_body_out = dir + "\\" + "output_temp\\" + fileName + "_hd_intermediate" + ext;
} // end of if
else
{
Writer3 = new StreamWriter(dir + "\\" + "output_temp\\" + fileName + "_out" + ext) { AutoFlush = true };
} // end of else
using (StreamReader Reader = new StreamReader(#filename))
{
while (!Reader.EndOfStream)
{
string inputLine = string.Empty;
inputLine = Reader.ReadLine();
rowCount++;
if (filename.Contains("RO_"))
{
if (rowCount <= 4)
{
Writer.WriteLine(inputLine);
}
if (rowCount >= 5)
{
Writer2.WriteLine(inputLine);
}
}
else
{
{ Writer3.WriteLine(inputLine); }
Should I close here?
if (filename.Contains("RO_"))
{
Writer = new StreamWriter(dir + "\\" + "output_temp\\" + fileName + "_hd_intermediate" + ext) { AutoFlush = true };
Writer2 = new StreamWriter(dir + "\\" + "output_temp\\" + fileName + "_body_out" + ext) { AutoFlush = true };
path_body_out = dir + "\\" + "output_temp\\" + fileName + "_hd_intermediate" + ext;
} // end of if
else
{
Writer3 = new StreamWriter(dir + "\\" + "output_temp\\" + fileName + "_out" + ext) { AutoFlush = true };
} // end of else
Or here?
if (filename.Contains("RO_"))
{
if (rowCount <= 4)
{
Writer.WriteLine(inputLine);
}
if (rowCount >= 5)
{
Writer2.WriteLine(inputLine);
}
}
else
{
{ Writer3.WriteLine(inputLine); }
}
If you can't reorganize this code so that every StreamWriter instance can be wrapped in a using(), then perhaps you can do something like this:
StreamWriter Writer = null, Writer2 = null, Writer3 = null;
try
{
// your existing code
}
catch
{
// Handle
}
finally
{
if (Writer != null)
Writer.Close();
if (Writer2 != null)
Writer2.Close();
if (Writer3 != null)
Writer3.Close();
}
This ensures that no matter what error(s) happen within the try that your writers will be closed.
In my opinion, conditionally instantiating objects is a smell and you should work on having different implementations based on filename.Contains("RO_"). You could use the strategy pattern and have different file processor interface implementations, choosing the correct one based on the filename. Each implementation would only know how to write to the locations it needs. This would allow you to correctly use a using() around each writer.
Nomrally if you are using disposable objects, I would say use a using block. However, since you are conditionally instatiating disposable objects, I think the use of a try-finally block would be your best bet.
Declare disposable objects and intialize them to null outside of a try block.
Initialize the disposable objects to the instances you want inside of a try block. Take care not to change this reference anywhere inside of your try-block once you have created a disposable object.
Also inside of your try block, do everything you need to do with the disposable objects.
After your try block create a finally block (a catch block is optional, but you will need a finally block for this method to do its job.) and inside the finally block, check if the variables you declared to hold the disposable objects aren't null. and if they are not null, close them and make them null.
StreamWriter writer = null;
try {
if (condA) {
writer = new StreamWriter("filePath1");
} else if (condB) {
writer = new StreamWriter("filePath2");
} else {
writer = new StreamWriter("filePath3");
}
// do things with writer
} catch (Exception ex) {
} finally {
if (writer != null) {
writer.close();
writer = null;
}
}
I'm developing an application that reads a xml file folder , and each file it to do some checks and copied to a new folder based on some criteria.
But memory usage continues to grow when it arrives in the foreach loop , and I believe that should not happen , because the variables do not increase at each iteration , are only overwritten.

How can I determine what 's going on?
The value of a variable pointing to a reference type is not the object at all, its just the memory address where the object lives.
So when you do the following:
while (true)
{
var myVariable = new MyReferenceType();
}
The only memory you are really reusing is the variable itself (think of a 32 or 64 bit pointer). But on every iteration your are allocating somewhere in memory space enough to fit the new object you've just created and that memory is most definitely not the memory reserved to the previous object.
This is essentially why your memory usage is growing. The "old" objects of previous iterations with no live reference will eventually get collected by the GC, but that could be never if the GC decides that it has enough memory available to avoid it.
I am creating application to delete files for more than 15 days in past, I've created a project using the C# language "multithreading" to be able to delete these files, but its only reading the first file with the error
The directory name is invalid
Can anyone help me on this please?
private void process3()
{
//DirectoryInfo info1 = new DirectoryInfo(#"\\10.4.9.202\d\PapyrusRes\appdata\");
DirectoryInfo info1 = new DirectoryInfo(#"\\DXB-RASO-MCH\Users\oalahmad\Dropbox\backup\Backup5\Desktop\New folder2");
// long Size = 0;
//C:\Users\oalahmad\Dropbox\backup\Backup5\Desktop\New folder2
String[] filePaths = (from fls in info1.EnumerateFiles()
where (fls.LastWriteTime.Date < DateTime.Today.AddDays(-15))
select fls.FullName).ToArray();
int i = 0;
if (!File.Exists(logPath3))
{
// Create a file to write to.
using (StreamWriter sw = File.CreateText(logPath3))
{
sw.WriteLine("Deletion Process History:");
sw.WriteLine(" ");
sw.WriteLine(" ");
}
}
//stopwatch.Start();
try
{
foreach (String f in filePaths)
{
DirectoryInfo info = new DirectoryInfo(f);
int difference = DateTime.Today.Subtract(info.LastWriteTime).Days;
textBox2.BeginInvoke(new Action(() =>
{
textBox2.Text += "Folder Name: " + Path.GetFileName(f) +
"\r\nDate Modified: " + difference +
"\r\n------\r\n";
}));
Thread.Sleep(10);
i++;
Directory.Delete(f, true);
count++;
}
using (StreamWriter sw = File.AppendText(logPath3))
{
sw.WriteLine("Successful at: " + DateTime.Now + " " + count +
" files were deleted");
}
}
catch (Exception ex)
{
// log errors
// Write your content here
using (StreamWriter sw = File.AppendText(logPath3))
{
if (count == 0)
sw.WriteLine("Unsuccessful at: " + DateTime.Now + " Error: " +
ex.Message);
else
sw.WriteLine("Unsuccessful at: " + DateTime.Now + " " + count +
" files were deleted" + " Error: " + ex.Message);
}
}

I'm using Streamwriter to save my list data to a text file, but the file is always empty when I open it.
I can get the list to display all of the inputs, so the list works. Heres the code for the filewriter.
private void SaveToFile()
{
string taxpayerLine;
string taxpayerFile;
string myFileName;
FileInfo myFile;
SaveFileDialog taxpayerFileChooser;
StreamWriter fileWriter;
taxpayerFileChooser = new SaveFileDialog();
taxpayerFileChooser.Filter = "All text files|*.txt";
taxpayerFileChooser.ShowDialog();
taxpayerFile = taxpayerFileChooser.FileName;
taxpayerFileChooser.Dispose();
fileWriter = new StreamWriter(taxpayerFile, true);
foreach (Taxpayer tp in Taxpayers)
{
taxpayerLine = tp.Name + "," +
tp.Salary.ToString() + "," +
tp.InvestmentIncome.ToString() + "," +
(tp.InvestmentIncome + tp.Salary).ToString() + "," +
tp.GetRate().ToString() + "," +
tp.GetTax().ToString();
fileWriter.WriteLine(taxpayerLine);
}
fileWriter.Close();
fileWriter.Dispose();
myFile = new FileInfo(taxpayerFile);
myFileName = myFile.Name;
MessageBox.Show("Data Saved to " + myFileName);
}
You can try changing your code like this:
private void SaveToFile()
{
string taxpayerLine;
string taxpayerFile = string.Empty;
string myFileName;
FileInfo myFile;
using (SaveFileDialog taxpayerFileChooser = new SaveFileDialog())
{
taxpayerFileChooser.Filter = "All text files|*.txt";
if (DialogResult.OK == taxpayerFileChooser.ShowDialog())
{
taxpayerFile = taxpayerFileChooser.FileName;
}
}
if (!string.IsNullOrEmpty(taxpayerFile))
{
using (StreamWriter fileWriter = new StreamWriter(taxpayerFile, true))
{
foreach (Taxpayer tp in Taxpayers)
{
taxpayerLine = tp.Name + "," +
tp.Salary.ToString() + "," +
tp.InvestmentIncome.ToString() + "," +
(tp.InvestmentIncome + tp.Salary).ToString() + "," +
tp.GetRate().ToString() + "," +
tp.GetTax().ToString();
fileWriter.WriteLine(taxpayerLine);
}
}
myFile = new FileInfo(taxpayerFile);
myFileName = myFile.Name;
MessageBox.Show("Data Saved to " + myFileName);
}
else
{
MessageBox.Show("Data not saved");
}
}
The using statement explicit calls the Dispose() method of disposable objects after the block execution. http://msdn.microsoft.com/en-us/library/yh598w02.aspx
