如何使用SQL Server在Silverlight中保存图像

How to save image in silverlight using sql server

严格讲，通常您不将图像保存在Silverlight中(除非您使用的是客户端数据库，但这违背了使用数据库存储文件的整个目的).这样做的方法是在您在Silverlight应用程序中引用的网站端编写WCF RIA服务.此服务将以字节数组形式接收文件，并使用该数组将数据写入数据库.

Strictly speaking, you normally don''t save the image in Silverlight (unless you are using a client side database, but this defeats the whole purpose of having a database to store files). The way to do this is to have a WCF RIA service written at the website end which you reference in the Silverlight application. This service will receive the file as a byte array, and use that array to write the data to the database.
