訪問HealthMonitoring提供者設定編程

Question

我已經建立了ASP.Net健康監測在web.config中：

<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> 

而且我試圖讀取該供應商的配置代碼：

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：不是實際的產品代碼，爲了簡明起見硬編碼&]
問題：儘管ElementInformation.Properties集合包含如預期的那樣，值是「Nothing」，「Properties（」to「）」的所有其他屬性也是如此。
如何訪問提供程序的設置？

Answer 1

在C＃：

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

section.Providers [3] .Parameters [ 「到」]返回「me@myhost.com」。

（3假定供應商名單並沒有在web.config中清除。）

Answer 2

我使出讀取web.config文件爲一個XML文檔，並使用與XPath的選擇節點：基於AUSteve的配置/ System.Web程序/ healthMonitoring /供應商/ * [@名稱]

Answer 3

回答我用下面的代碼。

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

可以使用初始化方法來訪問你在web.config中指定的屬性。剛剛訪問NameValueCollection中（和刪除您的自定義屬性被稱爲base.Initialize之前）
