来自Type的Typecast。从Type转换为model

Question

我有一个模型，我从Type获得。该模型属于Type BasePage。我可以将其转换/转换为Type类型吗？这个页面可以有10种不同的类型，所以我真的会从Type的转换/转换中受益。

Type pageType = page.GetType();

//this is what im trying to do but from the Type instead
var newPageOfType = (pageType)pageToCast; //I would usually use this Typecast

更新
用适当的示例代码更新了我的问题。所有pageType类型都来自相同的BasePage

Answer 1

最常见的方法是实际进行演员表，看看它是否成功：

var newPage = page as SomeDerivedPageClass;
if (newPage != null)
{
    // the cast succeeeded, page was actually of the derived type
}
else
    // the passed object wasn't what you were expecting. ignore it,
    // throw an error, log the error, whatever is appropriate.

Answer 2

只要value参数实现Convert.ChangeType，您就可以使用IConvertible。

Type pageType = page.GetType();
var newPageOfType = Convert.ChangeType(pageToCast, pageType);
