关于couldnotloadtype的信息

运行程序显示这个错误。是什么意思该怎么解决

可能是模板的问题，去这里看看解决的方法/edit/其中的方法有好几种，给你一个先试试（步骤1：找到该文件所在的路径。在word中选择菜单[工具]-[选项]-[文件位置]，然后双击“用户模板”，弹出一个“修改位置”对话框，从中就可以找到Normal.dot文件的路径，例如：C:\DocumentsandSettings\Administrator\ApplicationData\Microsoft\Templates.其中Administrator可以是其他的登陆用户名。步骤2：删除该Normal.dot）或者你可以重装公软件，资料不会丢失。

红色警戒2卸载时出现could not load intialization file那是咋回事

去网上下载个卸载软件，应该能搞定。实在不行就先删了，再用超级兔子清理一下注册表。

Could not load type 是什么意思

Could not load type

无法加载类型

双语对照

例句:

1.

Why not load up like a fiend?

何不像高手一样复习呢？

缺少DataSource配置文件

由于我们做的是微服务的架构，所以在创建一个新的服务时，我拷贝的是之前项目的东西，由于少拷贝了一个DataSource的配置类，报了如下的错误：

解决方法：添加DataSource配置类。

Could not load type 'System.Security.SecurityRulesAttribute' from assembly 'System.Web.Extensions'

一看就是Unity中反射失败，你要跟踪下Unity里面的代码，看它具体是怎样调用反射的。一般像这种动态反射加载DLL时，都会在配置文件中进行配置，初步估计是配置文件的问题。
