c# - 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);
   }
}

如何将图像大小从大 (800 x 600) 更改为小 (100x80) 并保存？

你可以试试这个库: http://nuget.org/packages/ImageResizer

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

或者您可以获得纯 C# 库并在您的应用程序中使用它。查看这些帖子:
