我使用.NET Framework 4.5与econnect的dll的12.0.0.0版本。任何人有任何想法？

Answer 1

System.BadImageFormatException异常是这里的线索。这通常是在32位和64位程序集之间不匹配的情况下。例如，如果IIS以32位模式运行，但解决方案引用64位“Microsoft.Dynamics.GP.eConnect”程序集。

因此，请确保您引用了“Microsoft.Dynamics.GP.eConnect”程序集的正确版本。 64位版本安装在“C：\ Program Files \ Microsoft Dynamics \ eConnect 12.0 \ API \”中，32位版本位于“C：\ Program Files文件（x86）\ Microsoft Dynamics \ eConnect 12.0 \ API \ “
