在WP7代码中检测DesignTime(Detect DesignTime in WP7 code)

 简单的问题，没有人知道如何检测代码是否与WP7设计时执行？ HtmlPage.IsEnabled的通常Silverlight解决方案在此上下文中不起作用。 

simple question, does anyone know how to detect whether code is executed design-time with WP7? The usual Silverlight solution of HtmlPage.IsEnabled doesn't work in this context.

 如果要使用.Cast方法，则需要实现转换运算符。 你可以在这里查看如何做到这一点。 如何为班级提供自定义演员支持？ 
 

 或者您可以使用.Select方法执行此操作，但您需要自己初始化每个对象。 
 

//Get Data
var data =  db2Repo.GetDB2Data();

var sqlData = data.Select(x => 
    new Common.Sql.MyModel(){ 
    // Do your mapping here 
    });

//Post Data 
sqlRepo.PostToSql(sqlData );

 

 我对此场景的建议：如果这些模型是您域的一部分，请在架构告诉您的时候创建映射。 否则，只需创建构造函数即可进行映射。

If you want to use the .Cast method, you need to implement the casting operators. You can check how to do it here. How do I provide custom cast support for my class?
 

Or you can do this using the .Select method, but you'll need to initialize each object by yourself.
 

//Get Data
var data =  db2Repo.GetDB2Data();

var sqlData = data.Select(x => 
    new Common.Sql.MyModel(){ 
    // Do your mapping here 
    });

//Post Data 
sqlRepo.PostToSql(sqlData );

 

My suggestion for this scenario: If these models are part of your domain, create the mapping in whenever your architecture tells you to do. Otherwise, just create constructors to do the mapping.
