}
private static ImageCodecInfo GetEncoderInfo(string mimeType)
{
    // Get image codecs for all image formats
    ImageCodecInfo[] codecs = ImageCodecInfo.GetImageEncoders();

    // Find the correct image codec
    for (int i = 0; i < codecs.Length; i++)

推荐答案

删除

img.Save("check1.jpg", jpegCodec, encoderParams);

行并将Image实例 img 用于您想要的任何内容。我想你不知道如何使用 Image ，但为了获得更多的帮助，你需要告诉我们你想用它做什么。在UI（ASP.NET，Winforms，WPF）中显示它？

line and use the Image instance img to whatever you want. I guess you don't know how to use Image, but to get futher help on that front you'll need to tell us what you want to use it for. Display it in an UI (ASP.NET, Winforms, WPF)?
