You can print the entire stack trace by using a try/catch around the code that can throw and then using <a href="http://msdn.microsoft.com/en-us/library/swx4tc5e.aspx" rel="nofollow noreferrer">Console.WriteLine</a> to show the exception object:

<pre><code>try
{
 new Program().Run();
}
catch (Exception exception) // Prefer to catch a more specific execption.
{
 Console.WriteLine(exception);
}
</code></pre>

Output:

<pre><code>System.IndexOutOfRangeException: Index was outside the bounds of the array.
 at Program.Run() in C:\Console Application1\Program.cs:line 37
 at Program.Main(String[] args) in C:\Console Application1\Program.cs:line 45
</code></pre>

The first line shows the type of the exception and the message. The second line shows the file, function and line number where the exception was thrown. You can also see the locations of other calls on the call stack in the following lines.

You can also get file and line numbers for uncaught exceptions. You can do this by adding a handler for the <a href="http://msdn.microsoft.com/en-us/library/system.appdomain.unhandledexception.aspx" rel="nofollow noreferrer">AppDomain.UncaughtException</a> event on the current AppDomain:

<pre><code>static void Main(string[] args)
{
 AppDomain.CurrentDomain.UnhandledException += CurrentDomain_UnhandledException;
 new Program().Run();
}

static void CurrentDomain_UnhandledException(object sender, UnhandledExceptionEventArgs e)
{
 Console.WriteLine(e.ExceptionObject);
}
</code></pre>

This shows a similar output to above.

blocks|key|1341798|text|您可以通过访问Exception.StackTrace获得堆栈跟踪，这是一个字符串，因此您可以使用Write或WriteLine方法将其打印到控制台。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1341799|entityMap^0|7|K|1D|5|1J|9|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]|$9|M|A|N|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|O|8|@]|D|@]|E|$]]]|G|$]]

You can get the stack trace by accessing <code>Exception.StackTrace</code> which is a string so you can print it to the console by using the <code>Write</code> or <code>WriteLine</code> methods.

blocks|key|75238|text|Console.WriteLine(exception.StackTrace);|type|code-block|depth|inlineStyleRanges|entityRanges|data|syntax|javascript|75239|确保应用程序处于Debug模式，或包含调试符号(+.mdb文件)，以便出现行号。|unstyled|offset|length|style|CODE|75240|entityMap^0|0|8|5|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$B|C]]|$1|D|3|E|5|F|7|N|8|@$G|O|H|P|I|J]]|9|@]|A|$]]|$1|K|3|-4|5|F|7|Q|8|@]|9|@]|A|$]]]|L|$]]

<pre><code>Console.WriteLine(exception.StackTrace);
</code></pre>

Make sure your application is in <code>Debug</code> mode or include the debug symbols (the .mdb file) in order for line numbers to appear.

blocks|key|1342216|text|您可以在最后一行的堆栈跟踪(Exception.StackTrace+property)中找到它，但只有在编译了包含调试信息的代码时才能找到它。否则，行号将未知。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1342217|entityMap^0|E|T|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|K|8|@]|D|@]|E|$]]]|G|$]]

You can find it in the stack trace (<code>Exception.StackTrace property</code>), on the last line, but only when your code has been compiled with debugging information included. Otherwise the line number will be unknown.

Can someone please tell me how to get the line number of the code where the error occurred and display it to the console?

Other information like the file name or method name would be very handy.
