c# - Web服务启动失败: Could not load file or assembly

Question

我的 Web 服务出现问题，无法再运行。之前安装的是64位版本，现在安装的是32位版本。然而，它似乎正在寻找64位版本的ChilkatDotNet2.dll，这很奇怪。 MSI 包安装的版本是 X86。

C:\Program Files (x86)\Sipp\Market Server\bin>asminfo.exe ChilkatDotNet2.dll ChilkatDotNet2, Version=9.3.0.0, Culture=neutral, PublicKeyToken=eb5fc1fc52ef09b d | X86

我启用了 FusionLog，它给出了以下输出:

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.BadImageFormatException: Could not load file or assembly 'ChilkatDotNet2' or one of its dependencies. An attempt was made to load a program with an incorrect format.
