下面是我的Windows服务代码。当我调试代码时,我得到错误/异常:

CSMessageUtility的类型初始化式。CSDetails抛出了一个异常。

检查TypeInitializationException的InnerException属性;它可能包含有关潜在问题的信息,以及问题发生的确切位置。

其他回答

退出Visual Studio并重新打开它为我解决了这个问题。

另一种可能导致这种情况的情况是,当你有一段代码调用:

string sParam = **ConfigurationManager.AppSettings["SOME_PARAM"].ToString();

请记住,必须使用OWSTIMER.EXE.CONFIG文件进行配置文件设置。我有一个App.config文件,我试图读取,我得到这个错误,因为在我的作业实例的实例化,我有一行在我的代码是引用配置。AppSettings & Configuration.ConnectionStrings。只要确保你走的是这条路:

C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\BIN

并将您的配置设置放在OWSTIMER.EXE.CONFIG文件中。

由于程序集的运行时版本之间不匹配,我遇到了这个问题。请验证主程序集(调用应用程序)和引用的程序集的运行时版本

In my case, I had a helper class that was static. In that class was a method to initialize a SqlCommand dependent on variables. As this was being called in several places I moved it to the helper class and called as needed, so this method was also static. Now I had a global property that was the connection string in Global.asax pointing to the connection string in web.config. Intermittently I would get "The type initializer for 'Helper' threw an exception". If I moved the method from the Helper class to the class where it was being called from all was good. The inner exception complained of the object being null (Helper class). What I did was add Using Helper to Global.asax and even though it was not being used by Global.asax this solved the problem.

当抛出这些初始化错误时要检查的另一件事是检查服务器上是否安装了目标. net版本。您可以右键单击该项目并查看应用程序的目标。net版本。
