Question

我在web.config中设置了ASP.Net运行状况监控：

<healthMonitoring enabled="true">
<providers>
<clear />
<add name="CriticalMailEventProvider" type="System.Web.Management.SimpleMailWebEventProvider"
from="appErrors@myhost.com" to="me@myhost.com"
bodyHeader="Application Error!" bodyFooter="Please investigate ASAP." 
subjectPrefix="ERROR: " buffer="true" bufferMode="Critical Notification" 
maxEventLength="8192" maxMessagesPerNotification="1"
/>
</providers></healthMonitoring>

我试图在代码中读取此提供程序的配置：

Dim HealthMonitoring As System.Web.Configuration.HealthMonitoringSection
Dim ToAddress As String
HealthMonitoring = CType(WebConfigurationManager.GetWebApplicationSection("system.web/healthMonitoring"), HealthMonitoringSection)
ToAddress = HealthMonitoring.Providers(0).ElementInformation.Properties("to").Value.ToString

[注意：不是实际的生产代码，硬编码＆amp;为简洁而浓缩]
问题：虽然ElementInformation.Properties集合包含预期的键，但Value是“Nothing”，所以“Properties（”to“）”的所有其他属性也是如此。如何访问提供商的设置？

Answer 1

在C＃中：

HealthMonitoringSection section = WebConfigurationManager.GetWebApplicationSection("system.web/healthMonitoring") as HealthMonitoringSection;

section.Providers [3] .Parameters [“to”] 返回“me@myhost.com”。

（3假设在web.config中没有清除提供者列表。）

Answer 2

我已经将web.config文件作为XML文档阅读，并使用XPath选择的节点：configuration / system.web / healthMonitoring / providers / * [@ name]

Answer 3

根据AUSteve的回答，我使用了以下代码。

Dim xmldoc As New System.Xml.XmlDocument
xmldoc.Load(HttpContext.Current.Server.MapPath("Web.config"))
Dim xmlnsManager As System.Xml.XmlNamespaceManager = New System.Xml.XmlNamespaceManager(xmldoc.NameTable)
xmlnsManager.AddNamespace("nc", "http://schemas.microsoft.com/.NetConfiguration/v2.0")

Dim emailTo As String = xmldoc.SelectSingleNode("/configuration/system.web/healthMonitoring/providers/add", xmlnsManager).Attributes("to").Value.ToString

Answer 4

您可以使用Initialize方法访问您在web.config中指定的属性。只需访问NameValueCollection（并在调用base.Initialize之前删除它的自定义属性）

本文展示了C＃实现：http://www.tomot.de/en-us/article/6/asp.net/how-to-create-a-custom-healthmonitoring-provider-that-sends-e-mails
