在MVC3中使用C#更改图像大小？

Question

[HttpPost]
public ActionResult AddImage(Image model)
{
   if (model.ImageData != null && model.ImageData.ContentLength > 0)
   {
      var fileName = Path.GetFileName(model.ImageData.FileName);
      var pathBig = Path.Combine(Server.MapPath("~/UploadedImages"), fileName);
      var pathSmall = Path.Combine(Server.MapPath("~/UploadedImages"), "small_" + fileName);


      // --> How to change image size to big(800 x 600)
     //      and small (100x80) and save them?

      model.ImageData.SaveAs(pathBig);
      model.ImageData.SaveAs(pathSmall);
   }
}

如何将图像大小更改为大(800 x 600)到小(100x80)并保存？

你可以尝试这个库:http: //nuget.org/packages/ImageResizer

它确实支持asp.net-mvc:http: //imageresizing.net/

或者你可以得到一个纯粹的C#lib并在你的应用程序上使用它.请参阅以下帖子:
