无法从web.config中读取值 [英] Failing to read value from web.config

问题描述

我正在使用推荐的方法从web.config文件中读取值(我认为).使用Visual Studio内置的Web服务器时，此方法工作正常，但如果使用本地IIS服务器，则失败.这是我正在使用的代码:

Hi,

I am using the recommended way to read values from the web.config file (I think). This works fine when using the web server built into Visual Studio but fails if I use the local IIS server. This is the code I am using:

public class Global : System.Web.HttpApplication
{
    protected void Application_Start( object sender, EventArgs e )
    {
        KeyValueConfigurationElement settingKeyValuePair;
        System.Configuration.Configuration rootWebConfig = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration( "/" );
        settingKeyValuePair = rootWebConfig.AppSettings.Settings[ "DomainForEmails" ];
        var v = settingKeyValuePair.Value;
}

变量 rootWebConfig 返回为NULL.我不知道为什么.任何帮助或建议，将不胜感激.

帕特里克

The variable rootWebConfig comes back as NULL. I have no idea why. Any help or advice would be very much appreciated.

Kind wishes, Patrick

推荐答案

您是否已将appsetting设置为:

Have you set appsetting as:

<appsettings>
     <add key="XmlFilePath" value="C:\yourpath here" /> 
</appsettings> 

如果已设置，则调试WebConfigurationManger对象上的值.

If it is already set, then debug the value on WebConfigurationManger object.
