View contents from .txt file from ASP.NET MVC App_Data directory

Question

I am using an error log function which writes exceptions in a ~/App_Data/ErrorLog.txt file in the following format-

Created on: .... + Environment.NewLine
Error Description: .... + Environment.NewLine
Source File: .... + Environment.NewLine
Method: .... + Environment.NewLine
Line: .... + Environment.NewLine
Column: .... + Environment.NewLine
________________________________________________________________________

Now i am viewing it in browser. But NewLine character disappeared. I used System.IO.StreamReader to read the texts.

How can i keep the html as the above format?

Or, Is there any way to open the .txt file directly in browser from App_Data directory?

Thank you.

when you want to put it on the page replace \n with <br />:

StringBuilder sb = new StringBuilder();
sb.Append("This is a test" + "\n");
sb.Append("This is a test" + "\n");
sb.Append("This is a test" + "\n");
var result = sb.ToString().Replace("\n", "<br />");
// put result on the page
// note: StringBuilder works like StreamReader when you call StreamReader.ReadToEnd().Replace("\n", "<br />");

• s.k.paul: Thanks Mohamad. It works. But @Html.Raw(ViewBag.ErrorLogs) is needed to render it on razor view page. Anyway, +1.
