我有一个使用 c# 和 system.data.sqlite.dll x64 构建的 WCF 服务库。构建配置是任何 CPU。它工作正常。但是，当我将 system.data.sqlite.dll 更改为 x86 位版本时，对于任何 CPU 配置，它都会成功构建，但是当我运行 wcf 方法时，它会给出错误，对于 x86 构建配置，它会成功构建，但在调试时会出现以下错误使用 wcftestclient。

System.BadImageFormatException: Could not load file or assembly 'file:///C:\Users\lala\Desktop\New folder\New folder\CoreServiceWCF\CoreServiceWCF\CoreServiceWCF2\bin\x86\Debug\VplusCoreServiceWCF.dll' or one of its dependencies. An attempt was made to load a program with an incorrect format.

有人帮我解决这个问题吗？

当为任何 CPU 构建程序集时，它将采用您运行的计算机的最佳配置，这意味着如果您有 64 位 Windows，它将以 64 位模式运行，如果它在 32 位，它将以 32 位模式运行位 Windows，问题似乎是这个程序集：VplusCoreServiceWCF.dll，所以我建议你先检查这个程序集的位数，看看它是否正确（在你的情况下可能是 64 位）

编辑：四处挖掘我发现 WCF 测试客户端仅在 64 位模式下运行，因此您可能需要将其强制为 32 位，为此您可以在此处找到所需的信息：我无法编译标准的“WCF 服务库” " x86 格式
