sao hok ai trả lời vậy ta???:sad:

Theo như cậu nói thì mình hiểu là Image nằm trong RichTexBox chứ không nằm trong phần attach

message.Body = (new TextRange(Body.Document.ContentStart, Body.Document.ContentEnd)).Text; 

Ở RichTextBox với x:Name = Body cậu chỉ lấy thuộc tính text của nó gửi đi nên làm sao có ảnh trong message.Body được.

Một email muốn hiển thị hình ảnh mà không nằm trong mục attach thì nó cần có định dạng html (theo như mình biết là thế), nghĩa là hình ảnh mà cậu gửi phải được lưu trữ sẵn trên mạng (source), sau đó chỉ cần chèn thẻ image vô html với nguồn là source.

mình đã thử chuyển body thành html rồi nhưng mà chỉ gửi được định dạng chứ còn image thì k gửi được
