Hello I have multiple text files in one location and they have names as shown below:-
A_L_PRTD_021345.txt , A_L_PRTD_432124 and so on...
I want to append the contents into single file and want to rename the single file as L_PRTD_Currentdate>.txt
How is it possible?
Can you please show some code for it?
First read each file using File.ReadAllLines(fileName) ;
Then create a single file and append the contents of other files in it
string[] contents1 = File.ReadAllLines(fileName1) ;
string[] contents2 = File.ReadAllLines(fileName2) ;
File.Create(newFileNameHere) ;
File.WriteAllLines(newFileNameHere, contents1) ;
File.AppendAllLines(newFileNameHere, contents2) ;
and so on ...

The following code will give you the last row number before every horizontal page break in an Excel worksheet:
foreach (Excel.HPageBreak pageBreak in worksheet.HPageBreaks)
{
int row = pageBreak.Location.Row - 1;
// ...

StreamReader reader = new StreamReader("C:\\ABC\\XYZ.txt");
I am reading a file using streamreader, the file is a HL7 file
MSH|^~\&|ABC|000|ABC|ABC|0000||ABC|000|A|00
PID|1|000|||ABC||000|A||||||||||
PV1|1|O||||||||||||||||||||||||||||||||||||||||||
OBR|1|||00||00|00|||||||||||ABC|00|0|0||||A|||||00||ABC|7ABC||ABC
OBX|1|ABC|ABC|1|SGVsbG8=
I need to find the line number of OBX, the file has character delimiters at the end of each line e.g. MSH|^~\&|ABC|000|ABC|ABC|0000||ABC|000|A|00*CR*LF
The reason I need this is that I need to get the Base64 inside the OBX field, and write it out as a file. my reader will always be a stream, I cannot use the file stream. The above code was an example, the following implementation is to be made in BizTalk and the file I will reading will be stream because that's how BizTalk allows me to access the information in of my file.
var lineNum = File.ReadLines(fname)
.Select((s, line) => new { s, line })
.First(x => x.s.StartsWith("OBX|"))
.line;

I created an application which has 2 labels and 1 textbox.
The first label will show the total number of days since the year began, while the second shows the number of tests in the year. In the textbox shows the number of tests that I have not studied.
When the program opens, you have to click a button to load an .txt file to get these numbers, they are saved when you exit by clicking in another button. I Wanted to know how to load the file and to save the parameters.
I'm developing in C#, grateful, sorry for bad english.
To read text use File.ReadAllLines
List<string> lines = File.ReadAllLines(path).ToList();
To write text use File.WriteAllLines
File.WriteAllLines(path, lines.ToArray());
Or some variation on those methods to suit your needs.
One approach would be this:
using System.IO;
using (var reader = new StreamReader(fileName))
{
string line;
while ((line = reader.ReadLine()) != null)
{
// Do stuff with your line here, it will be called for each
// line of text in your file.
}
}
Or, you could do:
List<String> txtStrings = File.ReadAllLines(path).ToList();
Or, come up with your own approach by reading up on this post.
