请求'system.net.webpermission，system，version = 4.0.0.0，culture = neutral，publickeytoken = b77a5c561934e089'类型的权限失败。 [英] Request for the permission of type 'system.net.webpermission, system, version=4.0.0.0, culture=neutral, publickeytoken=b77a5c561934e089' failed.

问题描述

如何解决请求类型'System.Net.WebPermission，System，Version = 4.0.0.0，Culture = neutral，PublicKeyToken = b77a5c561934e089'的权限失败。对于IIS中的中等信任级别，如果信任级别为满，我们将不会收到此错误！请为我提供解决方案。非常感谢提前。



我尝试了什么：



我尝试过给予信任等级=满，这将得到解决

解决方案

你没有。如果中等信任级别限制太多，您需要托管公司来创建和应用自定义策略：

如何：在ASP.NET 2.0中使用中信任⇒步骤3.（可选）基于中等信任创建自定义策略 [ ^ ]



你的代码中没有任何东西可以解决这个问题。如果有，那么首先拥有信任级别就没有任何意义！ ：）

How to resolve "Request for the permission of type 'System.Net.WebPermission, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed." for medium trust levels in IIS, if the trust level is "full" we will not get this error! Please provide me with a solution for this. Many thanks in advance.

What I have tried:

I have tried giving trust level = "Full", this will get resolved

解决方案

You don't. If the medium trust level is too restrictive, you need to get the hosting company to create and apply a custom policy:

There's nothing you can do in your code to work around this. If there was, then there wouldn't be any point in having the trust levels in the first place! :)
