| [Remove](../../aspose.words/node/remove/)() | Removes itself from the parent. |
| [ToString](../../aspose.words/node/tostring/)(*[SaveFormat](../saveformat/)*) | Exports the content of the node into a string in the specified format. |
| [ToString](../../aspose.words/node/tostring/)(*[SaveOptions](../../aspose.words.saving/saveoptions/)*) | Exports the content of the node into a string using the specified save options. |

## Remarks

To create a comment anchored to a region of text, you need to create a [`Comment`](../comment/) and then create [`CommentRangeStart`](../commentrangestart/) and `CommentRangeEnd` and set their identifiers to the same [`Id`](../comment/id/) value.

`CommentRangeEnd` is an inline-level node and can only be a child of [`Paragraph`](../paragraph/).

## Examples

Shows how print the contents of all comments and their comment ranges using a document visitor.

```csharp
Document doc = new Document();

Comment newComment = new Comment(doc)
{
    Author = "VDeryushev",
    Initial = "VD",
    DateTime = DateTime.Now
};

newComment.SetText("Comment regarding text.");

// Add text to the document, warp it in a comment range, and then add your comment.
Paragraph para = doc.FirstSection.Body.FirstParagraph;
para.AppendChild(new CommentRangeStart(doc, newComment.Id));
para.AppendChild(new Run(doc, "Commented text."));
para.AppendChild(new CommentRangeEnd(doc, newComment.Id));
para.AppendChild(newComment); 

// Add two replies to the comment.
newComment.AddReply("John Doe", "JD", DateTime.Now, "New reply.");
newComment.AddReply("John Doe", "JD", DateTime.Now, "Another reply.");

PrintAllCommentInfo(doc.GetChildNodes(NodeType.Comment, true));
```

Shows how print the contents of all comments and their comment ranges using a document visitor (PrintAllCommentInfo).

```csharp
/// <summary>
/// Iterates over every top-level comment and prints its comment range, contents, and replies.
/// </summary>
private static void PrintAllCommentInfo(NodeCollection comments)
{
    CommentInfoPrinter commentVisitor = new CommentInfoPrinter();

    // Iterate over all top-level comments. Unlike reply-type comments, top-level comments have no ancestor.
    foreach (Comment comment in comments.Where(c => ((Comment)c).Ancestor == null).ToList())
    {
        // First, visit the start of the comment range.
        CommentRangeStart commentRangeStart = (CommentRangeStart)comment.PreviousSibling.PreviousSibling.PreviousSibling;
        commentRangeStart.Accept(commentVisitor);

        // Then, visit the comment, and any replies that it may have.
        comment.Accept(commentVisitor);
        // Visit only start of the comment.
        comment.AcceptStart(commentVisitor);
        // Visit only end of the comment.
        comment.AcceptEnd(commentVisitor);

        foreach (Comment reply in comment.Replies)
            reply.Accept(commentVisitor);

        // Finally, visit the end of the comment range, and then print the visitor's text contents.
        CommentRangeEnd commentRangeEnd = (CommentRangeEnd)comment.PreviousSibling;
        commentRangeEnd.Accept(commentVisitor);

        Console.WriteLine(commentVisitor.GetText());
    }
