How to get raw request body in ASP.NET?

Question

In the HttpApplication.BeginRequest event, how can I read the entire raw request body? When I try to read it the InputStream is of 0 length, leadin

Answer 1

Pål's answer is correct, but it can be done much shorter as well:

string req_txt;
using (StreamReader reader = new StreamReader(HttpContext.Current.Request.InputStream))
{
    req_txt = reader.ReadToEnd();
}

This is with .NET 4.6.
