using System;
using System.IO;

class FileInput
{
	public static void Main()
	{
		string Path = null;
		

		Console.WriteLine("Please Enter The Path of the TXT File You Want See : ");
		Path = Console.ReadLine();

		StreamReader r = File.OpenText(Path);
		
		for (int i = 0; i < 20; i++)
		{
			Console.WriteLine(r.ReadLine());
			if (r.ReadLine() != null)
			{
				i = i;
			}
			else
			{
				i = 19;
			}
		}
	}

}

please help me to learn c# Thanks...

Are you saying it's not showing anything?

Um no, he said the following: "my program is not completely showing complete file...".

He is reading "some" lines -- not "all" lines...

From what I can see in the code, he is setting a maximum iteration count of 21 in his loop (0 to 20 = 21 iterations). If his text file has more than 21 lines, he will never get all lines from the file.

He could create a function that reads the lines from the file and returns a List<> of Strings that represent the lines in the file.

Example:

public List<string> ReadFileLines(string fileName)
{
   try
   {
	  List<string> allLines = new List<string>();

	  using (StreamReader reader = new StreamReader(fileName))
	  {
		 string line;
		 while ((line = reader.ReadLine()) != null)
		 {
			//
			// "line" is a line in the file. Add it to our List.
			//
			allLines.Add(line);
		 }
	  }
				
	  return allLines;
   }
   catch (IOException)
   {
	  // Bad things just happened...
	  return null;
   }
}

He's also skipping every other line:

Console.WriteLine(r.ReadLine());
if (r.ReadLine() != null)

Sorry.. i didn't get that far down in the code... lol

[p0rkjell0]

Sorry I didn't explain. I didn't get that far not because I couldn't... because I wouldn't...

i'm sure you understand...

yawn!
