关于ASPxGauges安全性问题 [英] About ASPxGauges Secutity Problem

问题描述

大家好，

我在项目中添加了一些AspxGauges，这是一个问题.我设置了自定义的Gauge控件，并将其另存为XML.页面加载如下:

Hello guys,

There is a problem that I added a few AspxGauges to my project. I set the customize Gauge control and save them out as XML. The page load is below:

protected void Page_Load(object sender, EventArgs e)
{
                this.gauges_yil.RestoreLayoutFromXml(MapPath("~/aspx/gauges_yil.xml"));
                this.gauges_m2.RestoreLayoutFromXml(MapPath("~/aspx/gauges_m2.xml"));
                this.gauges_kasa.RestoreLayoutFromXml(MapPath("~/aspx/gauges_kasa.xml"));
                this.ASPxGaugeControl4.RestoreLayoutFromXml(MapPath("~/aspx/ASPxGaugeControl4.xml"));
                this.ASPxGaugeControl5.RestoreLayoutFromXml(MapPath("~/aspx/ASPxGaugeControl5.xml"));
                this.ASPxGaugeControl6.RestoreLayoutFromXml(MapPath("~/aspx/ASPxGaugeControl6.xml"));
                
}

但是，在将其发送到服务器后出现了此错误:

However, I got this error after I sent it to the server:

Server Error in '/' Application.

推荐答案

错误看起来很容易理解:应用程序尝试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.

您似乎没有权限在服务器上保存文件.
看看是否有帮助: FIX:如何解决安全异常(ASP.NET)? [ MSDN:ASP.NET信任级别和策略文件 [ MSDN:如何:使用代码访问安全策略约束程序集 [

Error looks self explanatory: The application attempted to perform an operation not allowed by the security policy. To grant this application the required permission please contact your system administrator or change the application''s trust level in the configuration file.

Looks like you don''t have permission to save file on server.
