Question

Update:
ILSPY, DotPeek and JustDecompile automatically support what I am looking.

I just want to convert my C# XML Comments into Comments.

Input

<member name="P:...">
      <summary>.......</summary>
      <returns>
        ......
      </returns>
</member>

Output,

/// <summary>
/// ...
/// </summary>
/// <returns>...</returns>

Without more context for what your ultimately trying to get out of it, this should convert Xml into comments. Nothing real tricky going on here…

string content =
@"<member name=""P:..."">
  <summary>This is the summary.</summary>
  <returns>This is the return info.</returns>
  </member>";

XDocument doc = XDocument.Parse(content);                        
foreach (var member in doc.Descendants("member"))
{
     StringBuilder sb = new StringBuilder();

     sb.AppendLine("/// <summary>");
     sb.AppendLine("/// " + member.Descendants("summary").Select(e => e.Value).FirstOrDefault());
     sb.AppendLine("/// </summary>");

     sb.AppendLine("/// <returns>");
     sb.AppendLine("/// " + member.Descendants("returns").Select(e => e.Value).FirstOrDefault());
     sb.AppendLine("/// </returns>");

     // sb.ToString() contains the comments for this member
 }

You’ll probably need to do more to get it exactly how you want.
