.net本地程序集加载失败,CAS策略

Question

我们收到以下程序集加载错误.程序集从本地路径"C:\ Program Files\ASWorx Products\ASWorx\Bin \"加载.旧版本的二进制文件不存在问题.当我们通过电子邮件发送新二进制文件时,会出现此问题.构建设置不会更改.我们如何纠正这个问题？问题出现在Win7 32位机器上

File name: 'file:///C:\Program Files\ASWorx Products\ASWorx\Bin\ASConnexDI.dll' ---> System.NotSupportedException: An attempt was made to load an assembly from a network location which would have caused the assembly to be sandboxed in previous versions of the .NET Framework. This release of the .NET Framework does not enable CAS policy by default, so this load may be dangerous. If this load is not intended to sandbox the assembly, please enable the loadFromRemoteSources switch. See http://go.microsoft.com/fwlink/?LinkId=155569 for more information.

Answer 1

从错误消息中的链接:

如果已从Web复制应用程序,则Windows将其标记为Web应用程序,即使它位于本地计算机上也是如此.您可以通过更改文件属性来更改该指定,也可以使用该元素授予程序集完全信任.作为替代方法,您可以使用UnsafeLoadFrom方法加载操作系统已标记为已从Web加载的本地程序集.

尝试打开文件属性并单击"取消阻止":

Answer 2

我可以使用下面的链接解决此问题,并将设置添加到我的配置.

<configuration>
   <runtime>
      <loadFromRemoteSources enabled="true"/>
   </runtime>
</configuration>

Answer 3

我不得不使用该方法

Assembly.UnsafeLoadFrom()

而不是 Assembly.LoadFrom，它解决了我的问题...在此链接中找到它：
