Question

我们在客户端站点安装.Net 4.0 Full。当前的System.dll版本是4.0.30319.236。

我们的测试应用程序打开没有问题，我向同一网络上的WCF服务发起一个简单的“回声”。但是，当调用服务调用时，我得到了这个令人讨厌的错误：

Creating proxy
calling service method
ERROR: exception during service call and response process: Could not load file or assembly '0 bytes loaded from System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' or one of its dependencies. An attempt was made to load a program with an incorrect format.
System.BadImageFormatException

我们已经多次重新安装了框架，我尝试重新安装System.dll。什么都行不通。

我运行了.Net设置验证工具，没有错误返回。

System.dll的大小为3 510 600字节。

在服务器机器上（托管WCF服务），一切都很好。该机器上的.Net版本也是4.0.30319.236。

两台机器都安装在WinXP 32bit Professional SP3,2GB RAM上。

有什么想法吗？

谢谢，

克里斯

Answer 1

我们暂时搁置了这个问题。这台PC的问题似乎比看上去还要多。我们建议重新格式化和安装WinXP。

Answer 2

问题可能与csc.exe（代码生成器使用）不产生任何输出的问题有关。请查看此网址，了解如何解决问题：http://www.nooto.com/2011/02/net-framework-error-could-not-load-file-or-assembly/

无法加载程序集，来自System的0字节，BadImageFormatException
