StreamReader shows content on WriteLine function but return empty if using it in a variable-CodePudding

Can somebody help me solving this? When I use the reader on WriteLine it writes the message perfectly, but when I try to save as a variable too, it return an empty string. I'm doing this because I want to save the log on a file afterwards.

using (var stream = ex.Response.GetResponseStream())
                using (var reader = new StreamReader(stream, Encoding.UTF8))
                {
                    stream.Seek(0, SeekOrigin.Begin);
                    Console.WriteLine("Username: "   usernames[i]);
                    Console.WriteLine(reader.ReadToEnd());
                    content = reader.ReadToEnd().ToString();
                    Console.WriteLine(content);
                    Console.WriteLine("URL: https://api.bitbucket.org/2.0/users/"   usernames[i]   "\n");

CodePudding user response：

A reader reads in one direction: forward. If you want to read the same value twice, you have to back up and read it again.

Modify your code as follows:

using (var stream = ex.Response.GetResponseStream())
using (var reader = new StreamReader(stream, Encoding.UTF8))
{
    stream.Seek(0, SeekOrigin.Begin);
    Console.WriteLine("Username: "   usernames[i]);
    Console.WriteLine(reader.ReadToEnd());

    stream.Seek(0, SeekOrigin.Begin);
    content = reader.ReadToEnd().ToString();
    Console.WriteLine(content);
    Console.WriteLine("URL: https://api.bitbucket.org/2.0/users/"   usernames[i]   "\n");
