I tried to create this file by using StreamWriter class, but while using this class, it gives me "The file is being used by another process" error. I am more concerned about the formatting of the file. — Harsh, Jun 03 '15 at 05:33
Show us what you have done so far. Formatting the file should be pretty easy. StreamWriter is a good approach, you just need to format the string you write into the file with `String.Format` — ckruczek, Jun 03 '15 at 05:34

You might be trying to open the file more then once inside your code, that would lead to such exception. Another approach is using a StringBuilder instead of using StreamWriter to write the content, and then just use System.IO.File.WriteAllText to write the content of the StringBuilder to a file.
Using a StringBuilder will probably have higher memory use but lower IO use then using a StreamWriter. for more details, read this.

Here is how I would do it using a StringBuilder:

string FilePath = "c:/temp.data"; // this should hold the full path of the file
StringBuilder sb = new StringBuilder();

// Of course, you should use your one code to create the data, 
// this example is purely based on your format description.

sb.AppendLine("#Section Name").AppendLine();
sb.AppendLine("data");
sb.AppendLine("data");
sb.AppendLine("data").AppendLine();

File.WriteAllText(FilePath, sb.ToString());
