Learn how to add watermark in Outlook email messages
GroupDocs.Watermark also allows you to modify the body and subject of an email message. Below is the code sample to modify body and subject of an email Message:
AdvancedUsage.AddingWatermarks.AddWatermarksToEmailAttachments.EmailUpdateEmailBody
EmailLoadOptions loadOptions = new EmailLoadOptions();
// Specify an absolute or relative path to your document. Ex: @"C:\Docs\message.msg"
using (Watermarker watermarker = new Watermarker("message.msg", loadOptions))
{
EmailContent content = watermarker.GetContent<EmailContent>();
// Set the plain text body
content.Body = "Test plain text body";
// Set the html body
content.HtmlBody = "<html><body>Test html body</body></html>";
// Set the email subject
content.Subject = "Test subject";
// Save changes
watermarker.Save("message.msg");
}
GroupDocs.Watermark also provides the feature of embedding images in the body of the email message. Following is the code sample for embedding an image in an email:
AdvancedUsage.AddingWatermarks.AddWatermarksToEmailAttachments.EmailAddEmbeddedImage
EmailLoadOptions loadOptions = new EmailLoadOptions();
// Specify an absolute or relative path to your document. Ex: @"C:\Docs\message.msg"
using (Watermarker watermarker = new Watermarker("message.msg", loadOptions))
{
EmailContent content = watermarker.GetContent<EmailContent>();
content.EmbeddedObjects.Add(File.ReadAllBytes("sample.jpg"), "sample.jpg");
EmailEmbeddedObject embeddedObject = content.EmbeddedObjects[content.EmbeddedObjects.Count - 1];
content.HtmlBody = string.Format("<html><body>This is an embedded image: <img src=\"cid:{0}\"></body></html>", embeddedObject.ContentId);
watermarker.Save("message.msg");
}
You can also remove the embedded images from the body of the email message. Below is the code for removing embedded images:
AdvancedUsage.AddingWatermarks.AddWatermarksToEmailAttachments.EmailRemoveEmbeddedImages
EmailLoadOptions loadOptions = new EmailLoadOptions();
// Specify an absolute or relative path to your document. Ex: @"C:\Docs\message.msg"
using (Watermarker watermarker = new Watermarker("message.msg", loadOptions))
{
EmailContent content = watermarker.GetContent<EmailContent>();
for (int i = content.EmbeddedObjects.Count - 1; i >= 0; i--)
{
if (content.EmbeddedObjects[i].GetDocumentInfo().FileType == FileType.JPEG)
{
// Remove reference to the image from html body
string pattern = string.Format("<img[^>]*src=\"cid:{0}\"[^>]*>", content.EmbeddedObjects[i].ContentId);
content.HtmlBody = Regex.Replace(content.HtmlBody, pattern, string.Empty);
// Remove the image
content.EmbeddedObjects.RemoveAt(i);
}
}
watermarker.Save("message.msg");
}
Using GroupDocs.Watermark, you can also search for a text in the subject as well as in the body of the email message. Following is the code sample for searching text in the email message:
AdvancedUsage.AddingWatermarks.AddWatermarksToEmailAttachments.EmailSearchTextInBody
EmailLoadOptions loadOptions = new EmailLoadOptions();
// Specify an absolute or relative path to your document. Ex: @"C:\Docs\message.msg"
using (Watermarker watermarker = new Watermarker("message.msg", loadOptions))
{
SearchCriteria criteria = new TextSearchCriteria("test", false);
// Specify search locations
watermarker.SearchableObjects.EmailSearchableObjects = EmailSearchableObjects.Subject | EmailSearchableObjects.HtmlBody | EmailSearchableObjects.PlainTextBody;
// Note, search is performed only if you pass TextSearchCriteria instance to FindWatermarks method
PossibleWatermarkCollection watermarks = watermarker.Search(criteria);
// Remove found text fragments
watermarks.Clear();
// Save changes
watermarker.Save("message.msg");
}
GroupDocs.Watermark also allows listing all the message recipients using properties To, Cc and Bcc as shown in the following code sample.
AdvancedUsage.AddingWatermarks.AddWatermarksToEmailAttachments.EmailListRecipients
EmailLoadOptions loadOptions = new EmailLoadOptions();
// Specify an absolute or relative path to your document. Ex: @"C:\Docs\message.msg"
using (Watermarker watermarker = new Watermarker("message.msg", loadOptions))
{
EmailContent content = watermarker.GetContent<EmailContent>();
// List all direct recipients
foreach (EmailAddress address in content.To)
{
Console.WriteLine(address.Address);
}
// List all CC recipients
foreach (EmailAddress address in content.Cc)
{
Console.WriteLine(address.Address);
}
// List all BCC recipients
foreach (EmailAddress address in content.Bcc)
{
Console.WriteLine(address.Address);
}
}
