【问题描述】：

刚刚新建了一个应用，把信任级别Medium放到web.config中

<trust level="Medium" />

我需要在中等信任级别测试应用程序，因为我必须托管在共享服务器上。

现在运行应用程序并在这一行得到错误

@Html.ActionLink("XYZ", "Index", "Home", new {area=""}, new {@class="link" })

这是完整的错误：

描述：应用程序试图执行安全策略不允许的操作。要授予此应用程序所需的权限，请联系您的系统管理员或在配置文件中更改应用程序的信任级别。

异常详细信息：System.Security.SecurityException：请求“System.Security.Permissions.SecurityPermission, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089”类型的权限失败。

来源错误：

                 <span class="icon-bar"></span>
            </button>
             @Html.ActionLink("xyz", "Index", "Home", 
             new { area = "" }, new { @class = "navbar-brand" })
         </div>
        <div class="navbar-collapse collapse">

【解决方案1】：

几周前我遇到了同样的问题。我对信任中等级别的问题是我的 cshtml 在 javascript 标记处有一个“~”，例如：

<script src="~/Scripts/foo.js"></script>

删除“~”简单地解决了我的问题。

这是一个奇怪的错误，因为它指向 Razor 声明而不是“~”行。虽然在这种情况下“~”是一个特殊的 Razor 符号。

希望这可能会有所帮助。
