  • C#实现图片文件到数据流再到图片文件的转换

    //----引入必要的命名空间
    using System.IO;
    using System.Drawing.Imaging;

    //----代码部分----//

            private byte[] photo;//公用缓冲区
            public string SourFilePath;//源图片文件路径
            public string ObjFilePath;//目标图片路径

            public int FileToStream()//文件到流的转换
            {
