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。

如果由于任何原因断电或Visual Studio IDE崩溃,它会在你的bin/debug bin/release中导致这个问题…

只需删除内容并重新编译(从我的个人经验来看,当我的脚趾碰到复位按钮!)

其他回答

在WPF项目中有一个类似的案例。我的问题是这样写的:

DataTable myTable = FillTable(strMySqlQuery);

FillTable()返回一个基于SQL查询字符串的数据表。如果我做了“复制例外到剪贴板”选项,我认为它是,并粘贴到记事本,我可以看到消息。对我来说,它是输入不是一个有效的Base-64字符串,因为它包含一个非Base-64字符。

My actual problem wasn't that the query string had something that shouldn't be there, like I was thinking, because string strMySqlQuery = "SELECT * FROM My_Table" was my string and thought it could be the * or _, but the actual problem was in FillTable(), where I had a call to another function, GetConnection() that returned an OracleConnection object, in order to open it and retrieve and return the DataTable. Inside GetConnection() I was getting the app.config parameters for my connection string, and I had one of them misnamed, so it was setting a null value for the service account's password and not making the DB connection. So it's not always where the error is exactly correct for all circumstances. Best to dive into the function where the error is and debug step-by-step and ensure all values are getting filled with what you expect.

我的答案也与配置部分有关。如果你在c#的静态类或VB的Module.VB的配置文件中赋值,你会在运行时得到这个错误。

添加键=“log路径”值=“~/Error_Log/”

在Web中使用正斜杠。配置在运行时也会导致此错误。我刚刚通过放置反斜杠解决了这个问题

add key=“log路径”值=“~\ \ _log \”

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。

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.

我在两种情况下也犯过这个错误

在执行从BAL层重定向到DAL层时,我遇到了这个异常。内部异常表示“对象引用错误”。 网络。配置文件密钥不匹配。

希望这对解决你的问题有用。
