c# - 'CrystalDecisions.Shared.SharedUtils' 的类型初始值设定项抛出异常

Question

我正在做一个项目，遇到了一个问题。当我运行我的代码时，我收到此错误消息:

The type initializer for 'CrystalDecisions.Shared.SharedUtils' threw an exception

消息的标题是“TypeInitializerException was unhandled”。

我在这行代码收到此错误:

this.crystalReportViewer = new CrystalDecisions.Windows.Forms.CrystalReportViewer();

我一直在寻找解决此问题的方法，但我一直遇到另一个问题。我找到的关于如何解决这个问题的所有内容都表明平台目标应该更改为 x86。遵循该建议的所有评论总是积极的，因为它似乎对每个人都有效，但对我不起作用。我还尝试将平台目标设为 x64。当我这样做时，我没有收到前面提到的错误，而是收到一个新的错误:

The 'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine.

此 消息的标题是“未处理 InvalidOperationException”。 错误就在这一行:

db.Open();

db，当然，被设置为一个新的 OleDbConnection(connection)。连接 = 一个 Access 数据库。

为什么当平台目标是 x86 时我收到第一个错误而不是第二个错误，如果平台目标是 x64 则反之亦然？

Answer 1

这看起来像是原始问题:

InnerException: System.BadImageFormatException
   Message=Could not load file or assembly 'log4net, Version=1.2.10.0,
        Culture=neutral, PublicKeyToken=692fbea5521e1304'
   or one of its dependencies. An attempt was made to load a program
   with an incorrect format.

所以看起来要么您使用了错误的 log4net 版本，如果它针对不同的体系结构有多个版本，或者您只是错误地复制了程序集。日志的这一部分似乎也相关:

LOG: Attempting download of new URL
file:///C:/Users/Will/Desktop/Client_Manager/SyndicateII/bin/Debug/log4net.DLL.
ERR: Failed to complete setup of assembly (hr = 0x8007000b). Probing terminated.

这看起来像是您需要检查正确性的文件。
