I am trying to save data from public Web API to a txt file. However, it seems that somwhere here
using (var fs = FileService.CreateFile("filename.txt"))
{
// Add some text to file
var title = new UTF8Encoding(true).GetBytes(strContent);
fs.WriteAsync(title, 0, strContent.Length);
}
I am making a mistakes as I am missing some data at the end.
public void GetData()
{
var path = "https://www.cnb.cz/cs/financni-trhy/devizovy-trh/kurzy-devizoveho-trhu/kurzy-devizoveho-trhu/denni_kurz.txt";
string strContent;
var webRequest = WebRequest.Create(path);
using (var response = webRequest.GetResponse())
using(var content = response.GetResponseStream())
using(var reader = new StreamReader(content))
{
strContent = reader.ReadToEnd();
}
using (var fs = FileService.CreateFile("filename.txt"))
{
// Add some text to file
var title = new UTF8Encoding(true).GetBytes(strContent);
fs.WriteAsync(title, 0, strContent.Length);
}
var file = File.ReadAllLines(FileService.ReturnBinLocation("filename.txt"));
var results = new List<string>();
for (var a = 0; a < file.Length; a++)
{
results.Add(file[a]);
File.WriteAllLines(data, results);
}
var sub2 = File.ReadAllText(data);
sub2 = sub2.Replace('\n', '|').TrimEnd('|');
var split = sub2.Split('|');
var list = new List<DailyCourse>();
var i= 0;
do
{
var model = new DailyCourse();
model.Country = split[i]; i++;
model.Currency = split[i]; i++;
model.Amount = split[i]; i++;
model.Code = split[i]; i++;
model.Course = split[i]; i++;
list.Add(model);
} while ( i < split.Length);
var json = JsonSerializer.Serialize(list);
}
public static class FileService
{
public static FileStream CreateFile(string fileName)
{
var wholePath = ReturnBinLocation(fileName);
if (File.Exists(wholePath))
{
File.Delete(wholePath);
}
return File.Create(wholePath);

I have actually found out that it was this "Encoding.UTF8.GetBytes"when I switched it to Encoding.ASCII.GetBytes. It worked

I have created a blob triggered Azure function App that takes data from a TSV file and splits it up and writes data to a SQL database.
after the file have been read I would like to delete it from the blob container.
I'm currently studying and this is my first C# code ever so I hope you can help me out and be specific.
I have looked at the documentation for
CloudBlockBlob blob = CloudBlobContainer.GetBlockBlobReference(???????);
blob.DeleteIfExists();
but I can't seem to find out what to put here
here is my complete function. please if you could help me out where to insert the delete command as well I would appreciate it :)

the reason I want to delete the blob after is because the function reads the file more than once. when it does I get a timeout because it takes more than 5 mins to process data. may be that's why it starts more than once.
is there a way to write this so the process is quicker?
the TSV files can hold up to 100.000 lines sometime.
looking forward to some advise on this
Robin
If you look at the MSFT API for GetBlockBlobReference method it takes in a blobName as a parameter.
So ideally you already have the name from the param on your function. You can just do
CloudBlockBlob blob = CloudBlobContainer.GetBlockBlobReference(name);
blob.DeleteIfExists();
static void Main(string[] args) {
var file = File.Open(Directory.GetCurrentDirectory() + "/Net.pdf", FileMode.Open);
var pattern = new Regex("kullan", RegexOptions.IgnoreCase);
//this line is not working
TextExtractor textExtractor = new TextExtractor();
var dddd = ReadToEnd(file);
var textStrings = textExtractor.Extract(dddd);
var matches = pattern.Matches(textStrings.Text);
foreach (var item in matches)
{
Console.WriteLine(item);
}
}
You can try something like this:
File file = new File(myPDF);
//pattern
var pattern = new Regex("kullan", RegexOptions.IgnoreCase);
var textExtractor = new TextExtractor();
foreach (var page in file.Document.Pages)
{
var strings = textExtractor.Extract(page);
var matchingText = pattern.Matches(TextExtractor.ToString(strings));
}
Tika:
try
{
var result = new TextExtractor().Extract(yourPDF.pdf).Text;
Console.WriteLine(result.Text.Length);
foreach(var line in result)
{
if(line.contains("kullen"))
/** Do Something **/
}
}
catch(Exception e)
{
Console.WriteLine("Error occurred: " + e);
}
I did it like that, thank you your answer

string b = pdfText(Directory.GetCurrentDirectory()+ "/Net.pdf");
string a= "kullan";

if(sonuc==-1)
{
Console.WriteLine("not found");
}

{
Console.WriteLine("found from " + sonuc.ToString() + ". character");

The exception is happen most of the times but there are times it's working fine.
The exception is always the same

When I use a breakpoint on the line:

I see html content and in the content I see the text:
error occurred while processing your request. Return to the homepage of Sat24.com
What I want to do is somehow when the exception happen to start over again and try the download try the method ExtractDateAndTime.
I think using a timer some how and count back showing the user something like 30 seconds and try again. Will 30 seconds try will be consider as spam/flooding in the server site ?
This is the full class code but the exception is on this method ExtractDateAndTime.

What i want is in case of the exception happen to start over clean over again the whole class operation.
In Form1 i start the class operation first time once:
In top:
ExtractImages ei = new ExtractImages();
Then in constructor:
ei.Init();
The problem is this exception that sometimes happen.
You could go with something like Polly or the Transient Fault Handling Application Block to apply a retry strategy to your code.
Both packages provide multiple out-of-the-box components for various scenarios and you can always develop you own. Some of the included retry policies:
Incremental
Fixed interval
Exponential back-off
Retry
Retry for ever
Retry and wait
Wait and retry for ever

I'm working this code for almost 10 hours but i can not find out where i'm doing wrong .If you could help me you are really making my day.The problem is that I'm trying to add a new customer and save it in my list but when i'm click in submit button .It does not work nothing is saving in my list and keeps looping my other customers .
private void Sub_Click(object sender, RoutedEventArgs e)
{
customer newCus = new customer();
account newAcc= new account();
try
{
newCus.NAME = Nameadd.Text;
newCus.pin = pinadd.Text;
newAcc.PIN = pinadd.Text;
newAcc.accountnumber = Accountnumadd.Text;
newAcc.accounttype = 'C';
for (int i = 0; i < acclist.Count; i++)
{
{
if(newAcc.accounttype == 'C')
{
newAcc.PIN = pinadd.Text;
newAcc.accountnumber = Accountnumadd.Text;
newAcc.accounttype = 'S';
}
}
cuslist.add(newCus);
acclist.add(newAcc);
savefile();
saveaccount();
}
}
catch(Exception error)
{
MessageBox.Show(error.Message);
}
}
//save to customer file
public void savefile()
{
using (StreamWriter writer = new StreamWriter("account.txt"))
{
for (int i = 0; i < cuslist.Count; i++)
{
var info = new List<string>
{
acclist[i].accounttype.ToString(),
acclist[i].PIN,
acclist[i].accountnumber,
acclist[i].accountbalance.ToString()
};
var account = String.Join(";", info);
writer.WriteLine(account);
}
}
}
public void saveaccount()
{
using (StreamWriter writer = new StreamWriter("account.txt"))
{
for (int i = 0; i < acclist.Count; i++)
{
var info = new List<string>
{
acclist[i].accounttype.ToString(),
acclist[i].PIN,
acclist[i].accountnumber,
acclist[i].accountbalance.ToString()
};
var account = String.Join(";", info);
writer.WriteLine(account);
}
}
}
You have a problem in your "save" functions.
Here is what you have:
public void savefile()
{
using (StreamWriter writer = new StreamWriter("account.txt"))
{
for (int i = 0; i < cuslist.Count; i++)
{
var info = new List<string>
{
acclist[i].accounttype.ToString(),
acclist[i].PIN,
acclist[i].accountnumber,
acclist[i].accountbalance.ToString()
};
var account = String.Join(";", info);
writer.WriteLine(account);
}
}
}
public void saveaccount()
{
using (StreamWriter writer = new StreamWriter("account.txt"))
{
for (int i = 0; i < acclist.Count; i++)
{
var info = new List<string>
{
acclist[i].accounttype.ToString(),
acclist[i].PIN,
acclist[i].accountnumber,
acclist[i].accountbalance.ToString()
};
var account = String.Join(";", info);
writer.WriteLine(account);
}
}
}
If you look, the only difference is the for loops. You need to also update the inner portion to read from the correct collection, and also write to the correct output file.
Try the following:
public void savefile()
{
using (StreamWriter writer = new StreamWriter("customer.txt"))
{
for (int i = 0; i < cuslist.Count; i++)
{
var info = new List<string>
{
cuslist[i].accounttype.ToString(),
cuslist[i].PIN,
cuslist[i].accountnumber,
cuslist[i].accountbalance.ToString()
};
var customer = String.Join(";", info);
writer.WriteLine(customer);
}
}
}
public void saveaccount()
{
using (StreamWriter writer = new StreamWriter("account.txt"))
{
for (int i = 0; i < acclist.Count; i++)
{
var info = new List<string>
{
acclist[i].accounttype.ToString(),
acclist[i].PIN,
acclist[i].accountnumber,
acclist[i].accountbalance.ToString()
};
var account = String.Join(";", info);
writer.WriteLine(account);
}
}
}
I'm uploading a file using multipart data form and I need to keep the file description of the uploaded file. I'm using the following code
FileDescription temp = new FileDescription();
var task = Request.Content.ReadAsMultipartAsync(streamProvider).ContinueWith<IEnumerable<FileDescription>>(t =>
{
if (t.IsFaulted || t.IsCanceled)
{
throw new HttpResponseException(HttpStatusCode.InternalServerError);
}
var fileInfo = streamProvider.FileData.Select(i =>
{
var info = new FileInfo(i.LocalFileName);
temp.AssociatedSchool = 1;
temp.FileName = info.Name;
temp.LocalFileName = i.LocalFileName;
temp.FileSize = info.Length / 1024;
temp.IsFileValid = true;
temp.NoOfRecords = 1;
temp.UploadedBy = 1;
return temp;
});
return fileInfo;
});
This code doesnt set the values to the temp object. Can anyone tell me an alternate way to get the values? task.Result is always null. How can i get the values out of the thread?
Try change your sample like this
var descriptions = Request.Content.ReadAsMultipartAsync(streamProvider)
.ContinueWith<IEnumerable<FileDescription>>(t =>
{
if (t.IsFaulted || t.IsCanceled)
{
throw new HttpResponseException(HttpStatusCode.InternalServerError);
}
var fileInfo = streamProvider.FileData.Select(i =>
{
var info = new FileInfo(i.LocalFileName);
return new FileDescription(){
AssociatedSchool = 1;
FileName = info.Name;
LocalFileName = i.LocalFileName;
FileSize = info.Length / 1024;
IsFileValid = true;
NoOfRecords = 1;
UploadedBy = 1;
}
});
return fileInfo;
}).Result;
var temp = descriptions.First();//Possibly you need FirstOrDefault
