如果你正在工作使用ASP.NET Web页面，Web窗体或MVC，无论您使用何种类型的技术。您可以使用 WebImage 对象并使用它。



它有许多内置功能，你可以使用，调整大小或做你想做的事情。

..或者你可以从MSDN中学到它： http://msdn.microsoft.com/en-us/library/system.web.helpers.webimage（v = vs.111）的.aspx [ ^ ]



处理它的示例代码如下：

If you're working with ASP.NET Web Pages, Web Forms or MVC no matter what type of technology you're using. You can use the WebImage object and work with it.

It has many built-in functions that you can use, to resize or to do what so ever you want to do.

.. or you can learn it from the MSDN : http://msdn.microsoft.com/en-us/library/system.web.helpers.webimage(v=vs.111).aspx[^]

Sample code to deal with it is as:

// get the image from the request and work with it.
var photo = new WebImage().GetImageFromRequest();
// this code below does the job of resizing.
photo.Resize(width: 60, height: 60, preserveAspectRatio: true,
               preventEnlarge: true);

还要记住，ASP.NET Web Pages NuGet助手中的FileUpload控件还将整个代码转换为HTML代码。

Also remember, FileUpload control in the ASP.NET Web Pages NuGet helper also converts the entire code to the HTML code.
