c# 图片格式转换

发一个没什么技术含量的东东，调API的话会比较繁琐，代码如下

 

publicvoid ImageFormatter(string sourcePath, string distationPath, string format) {
            System.Drawing.Bitmap bitmap =new System.Drawing.Bitmap(sourcePath);
            switch (format.ToLower()) {
                case"bmp":
                    bitmap.Save(distationPath, System.Drawing.Imaging.ImageFormat.Bmp);
                    break;
                case"emf":
                    bitmap.Save(distationPath, System.Drawing.Imaging.ImageFormat.Emf);
                    break;
                case"gif":
                    bitmap.Save(distationPath, System.Drawing.Imaging.ImageFormat.Gif);
                    break;
                case"ico":
                    bitmap.Save(distationPath, System.Drawing.Imaging.ImageFormat.Icon);
                    break;
                case"jpg":
                    bitmap.Save(distationPath, System.Drawing.Imaging.ImageFormat.Jpeg);
                    break;
                case"png":
                    bitmap.Save(distationPath, System.Drawing.Imaging.ImageFormat.Png);
                    break;
                case"tif":
                    bitmap.Save(distationPath, System.Drawing.Imaging.ImageFormat.Tiff);
                    break;
                case"wmf":
                    bitmap.Save(distationPath, System.Drawing.Imaging.ImageFormat.Wmf);
                    break;
                default: thrownew Exception("无法转换此格式！");
            }
        }
