Hi,
During my last project i'm working with some SQL files, but i needed to got al of these files into one single file.
So i wrote a little program in order to contatenate all SQL files (or other text files) into one single file.
Here is the code
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
namespace ConcatFiles
{
class Program
{
static void Main(string[] args)
{
Console.Write("Enter Directory Path :");
String filePath = Console.ReadLine();
Console.Write("Enter Pattern (ex : *.sql) :");
String pattern = Console.ReadLine();
Console.Write("Enter Output FilePath :");
String output = Console.ReadLine();
if (String.IsNullOrEmpty(pattern))
pattern = "*.*";
if (!Directory.Exists(Path.GetFullPath(filePath)))
return;
String[] files = Directory.GetFiles(filePath, pattern);
StringBuilder sb = new StringBuilder();
foreach (String file in files)
{
sb.AppendLine();
using (TextReader tr = new StreamReader(file))
{
sb.Append(tr.ReadToEnd());
tr.Close();
}
sb.AppendLine();
}
// Write Output File
using (TextWriter tw = new StreamWriter(Path.GetFullPath(output)))
{
tw.WriteLine(sb.ToString());
tw.Close();
}
}
}
}

Someone told me in a comment that's he needs to Concatenate large files. The current implementation using StringBuilder may use a lot of RAM ..
So here is the new implementation for large files.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
namespace ConcatFiles
{
class Program
{
static void Main(string[] args)
{
Console.Write("Enter Directory Path :");
String filePath = Console.ReadLine();
Console.Write("Enter Pattern (ex : *.sql) :");
String pattern = Console.ReadLine();
Console.Write("Enter Output FilePath :");
String output = Console.ReadLine();
if (String.IsNullOrEmpty(pattern))
pattern = "*.*";
if (!Directory.Exists(Path.GetFullPath(filePath)))
return;
String[] files = Directory.GetFiles(filePath, pattern);
foreach (String file in files)
{
using (TextWriter tw = new StreamWriter(Path.GetFullPath(output), true))
{
using (StreamReader tr = new StreamReader(file))
{
while (!tr.EndOfStream)
{
tw.WriteLine(tr.ReadLine());
}
tr.Close();
}
tw.Close();
}
}
}
}
}
