Rename email fields

When rendering email messages, by default the API uses the English language to render field labels such as From, To, Subject etc. There might be the case when you want to change the label of the fields in email message’s header.
GroupDocs.Viewer is flexible enough to allow you to use the custom field labels for email header. The API provides a new property FieldTextMap in EmailOptions class to change the field labels.

Following code sample shows how to use custom field labels.

using (Viewer viewer = new Viewer("sample.msg"))
    HtmlViewOptions viewOptions = HtmlViewOptions.ForEmbeddedResources(pageFilePathFormat);
    viewOptions.EmailOptions.FieldTextMap[Field.From] = "Sender";
    viewOptions.EmailOptions.FieldTextMap[Field.To] = "Receiver";
    viewOptions.EmailOptions.FieldTextMap[Field.Sent] = "Date";
    viewOptions.EmailOptions.FieldTextMap[Field.Subject] = "Topic";
