4 ways to read the contents of a file with C# .NET

.NET supports a number of ways to read from a file. Here come 4 of them.

1. Using FileStream:

private void ReadFileWithFileStream()
	using (FileStream fileStream = File.Open(@"c:\mydirectory\source.txt", FileMode.Open, FileAccess.Read))
		using (StreamReader streamReader = new StreamReader(fileStream))

2. Using StreamReader:

private void ReadFileWithStreamReader()
	using (StreamReader reader = File.OpenText(@"c:\mydirectory\source.txt"))

StreamReader.ReadToEnd has an awaitable version ReadToEndAsync which you can use to read from the file asynchronously. If you don’t know what this means then start here.

3. Using File:

private void ReadFileWithFile()

4. Using BufferedStream:

private void ReadFileWithBufferedStream()
	using (FileStream fileStream = File.Open(@"c:\mydirectory\source.txt", FileMode.Open, FileAccess.Read))
		using (BufferedStream bufferedStream = new BufferedStream(fileStream))
			using (StreamReader streamReader = new StreamReader(bufferedStream))
