You could include <code>.PDB</code> symbol files associated to the assembly which contain metadata information and when an exception is thrown it will contain full information in the stacktrace of where this exception originated. It will contain line numbers of each method in the stack.

blocks|key|976665|text|简单的方法，使用Exception.ToString()函数，它会返回异常描述后的行。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|976666|您还可以检查程序调试数据库，因为它包含有关整个应用程序的调试信息/日志。|976667|entityMap^0|8|K|0|0^^$0|@$1|2|3|4|5|6|7|J|8|@$9|K|A|L|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|M|8|@]|D|@]|E|$]]|$1|H|3|-4|5|6|7|N|8|@]|D|@]|E|$]]]|I|$]]

Simple way, use the <code>Exception.ToString()</code> function, it will return the line after the exception description.

You can also check the program debug database as it contains debug info/logs about the whole application.

If you need the line number for more than just the formatted stack trace you get from Exception.StackTrace, you can use the <a href="http://msdn.microsoft.com/en-us/library/system.diagnostics.stacktrace.aspx" rel="noreferrer">StackTrace</a> class: 

<pre><code>try
{
 throw new Exception();
}
catch (Exception ex)
{
 // Get stack trace for the exception with source file information
 var st = new StackTrace(ex, true);
 // Get the top stack frame
 var frame = st.GetFrame(0);
 // Get the line number from the stack frame
 var line = frame.GetFileLineNumber();
}
</code></pre>

Note that this will only work if there is a pdb file available for the assembly.

In Global.resx file there is an event called Application_Error

it fires whenever an error occurs,,you can easily get any information about the error,and send it to a bug tracking e-mail.

I tried using the solution By @davy-c but had an Exception "System.FormatException: 'Input string was not in a correct format.'", this was due to there still being text past the line number, I modified the code he posted and came up with: 

<pre><code>int line = Convert.ToInt32(objErr.ToString().Substring(objErr.ToString().IndexOf("line")).Substring(0, objErr.ToString().Substring(objErr.ToString().IndexOf("line")).ToString().IndexOf("\r\n")).Replace("line ", ""));

Line numbers will be included in the stack trace if the library which generated the exception is compiled with debug symbols. This can be a separate file (*.pdb) or embedded in the library.
For .NET Core, .NET 5 and later, to have full exception line numbers in release builds, configure the project as follows:
<pre class="lang-xml prettyprint-override"><code>&lt;PropertyGroup&gt; 
 &lt;DebugSymbols&gt;true&lt;/DebugSymbols&gt;
 &lt;DebugType&gt;embedded&lt;/DebugType&gt;

 &lt;!-- Only enable the following if the line numbers mismatch --&gt;
 &lt;!--&lt;Optimize&gt;false&lt;/Optimize&gt;--&gt;
 
 &lt;!--
 Additional properties which may impact how printed line numbers match the source code line numbers are listed here:
 https://docs.microsoft.com/en-us/dotnet/core/run-time-config/compilation
 --&gt;
&lt;/PropertyGroup&gt;
</code></pre>
The above configuration will include debug symbols directly with the built files, which can be published as nugets.
An alternative to the above is to restore debug packages together with the main nuget packages, which is currently not yet supported: <a href="https://github.com/NuGet/Home/issues/9667" rel="nofollow noreferrer">https://github.com/NuGet/Home/issues/9667</a>
Now get the exception line numbers:
<pre class="lang-cs prettyprint-override"><code>try
{
 throw new Exception();
}
catch (Exception ex)
{
 // Get stack trace for the exception with source file information
 var st = new StackTrace(ex, true);
 // Get the top stack frame
 var frame = st.GetFrame(0);
 // Get the line number from the stack frame
 var line = frame.GetFileLineNumber();
}
</code></pre>
