我的第一步:gif图片转Base64字符串

string fileFullName=图片地址;
string base64Str=ImageToBase64(fileFullName)

public static string ImageToBase64(string fileFullName)
{
try
{
Bitmap bmp = new Bitmap(fileFullName);
MemoryStream ms = new MemoryStream();
bmp.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);
byte[] arr = new byte[ms.Length]; ms.Position = 0;
ms.Read(arr, 0, (int)ms.Length); ms.Close();
return Convert.ToBase64String(arr);
}
catch (Exception ex)
{
return null;
}
}

我的第二步:在html的img src中加载,如

<img src='data:image/gif;base64,/9j/4AAQSkZJRgABAQAAAQABAAD/2wBDAAkGBwgHBgkIBwgKCgkLDRYPDQwMDRsUFRAWIB0iIiAd

问题补充:

结果只是一帧的图像,是不是获取的base64只是当中的一帧?

不是被你保存为 jpg 了吗?

bmp.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);
