我的项目中有数据;它是Base64格式图像。 当我在Visual Studio中运行它时,我的 img src:

<img src="data:image/png;base64,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">

但是当它在IIS中发布时,字符串太长而图像不透明:

用于将位图图像转换为base64我使用方法:

using (MemoryStream ms = new MemoryStream())
            {
                img.Save(ms, ImageFormat.Png);
                byte[] imageBytes = ms.ToArray();
                return string.Format("data:image/png;base64,{0}",Convert.ToBase64String(imageBytes));
            }

有什么不对吗?
