Hi,

As part of my project, I can able to read the email using Gmail API but my problem is when I fetch the body, the signature is seen along with the body. So I need to remove the Gmail signature and fetch only the content or message of body.

is there is any other way to remove the Gmail signature (like regular expression ..)?

Please shed some light?

What I have tried:

I tried a lot, I use

MimeType == "text/html"

and get the formate in HTML and then find the class

//div[@class='gmail_signature']

using HTML document (using HtmlAgilityPack).

var nodes = htmlDoc.DocumentNode.SelectNodes("//div[@class='gmail_signature']").ToList();
                    if (nodes.Count > 0)
                    {
                        foreach (var item in nodes)
                        {
                            item.Remove();

                        }
                    }
var result = htmlDoc.DocumentNode.InnerText.Replace(System.Environment.NewLine, string.Empty);
                result = System.Web.HttpUtility.HtmlDecode(result);

But in some condition, the Gmail signature is coming.
