.NET: How to convert Exception to string?

Question

When an exception is thrown (while debugging in the IDE), i have the opportunity to view details of the exception:

Answer 1

I first tried Jason's answer (at the top), which worked pretty well, but I also wanted:

• To loop iteratively through inner exceptions and indent them.
• Ignore null properties and increases readability of the output.
• It includes the metadata in the Data property. (if any) but excludes the Data property itself. (its useless).

I now use this:

    public static void WriteExceptionDetails(Exception exception, StringBuilder builderToFill, int level)
    {
        var indent = new string(' ', level);

        if (level > 0)
        {
            builderToFill.AppendLine(indent + "=== INNER EXCEPTION ===");                
        }

        Action append = (prop) =>
            {
                var propInfo = exception.GetType().GetProperty(prop);
                var val = propInfo.GetValue(exception);

                if (val != null)
                {
                    builderToFill.AppendFormat("{0}{1}: {2}{3}", indent, prop, val.ToString(), Environment.NewLine);
                }
            };

        append("Message");
        append("HResult");
        append("HelpLink");
        append("Source");
        append("StackTrace");
        append("TargetSite");

        foreach (DictionaryEntry de in exception.Data)
        {
            builderToFill.AppendFormat("{0} {1} = {2}{3}", indent, de.Key, de.Value, Environment.NewLine);
        }

        if (exception.InnerException != null)
        {
            WriteExceptionDetails(exception.InnerException, builderToFill, ++level);
        }
    }

Call like this:

        var builder = new StringBuilder();
        WriteExceptionDetails(exception, builder, 0);
        return builder.ToString();
