I have a project developed from a console application in Visual C #, in which it sends emails, being the text in html format.
Today I put an image inside this html as follows:
"<img src='" + "http://www.site.com.br/logotipo.png" + "' width='300' height='70'></img>"
I would like to change this, taking this link, leaving the image in the project, and from there load the image. how could I be doing this?
You can convert to a base64 string and place it in src of the image:
I will consider that you have a System.Drawing.Image .
First, convert to a byte array ( byte[] ):
/// <summary>
/// Converte um objeto System.Drawing.Image em um array de bytes
/// </summary>
/// <param name="foto">System.Drawing.Image</param>
/// <returns>byte[]</returns>
public static byte[] ConvertImageToByte(System.Drawing.Image foto, System.Drawing.Imaging.ImageFormat format )
{
if (foto != null)
{
using (MemoryStream stream = new MemoryStream())
{
foto.Save(stream, format);
//stream.Flush();
byte[] pic = stream.ToArray();
return pic;
}
}
else return null;
}
-Using the function:
System.Drawing.Image imagem = .... Origem da sua imagem;
byte[] bImage = ConvertImageToByte(imagem,System.Drawing.Imaging.ImageFormat.Png);
Then, convert byte[] to string :
string base64String = Convert.ToBase64String(bImage , 0, bImage.Length);
Then put it in the html:
string html = "<img class=""plan-cover"" src=""data:image/png;base64," + base64String + """>";
Obs. If you need to set the image size (smaller than the original), it makes sense to resize the Image object and not html . The amount of data sent will be only what is needed.
