ContextInformation Class
Assembly: System.Configuration (in system.configuration.dll)
The ContextInformation object provides environment details related to an element of the configuration. For instance, you can use the IsMachineLevel property to determine whether a ConfigurationElement was set in Machine.config, or you can determine which hierarchy a ConfigurationElement belongs to by using the HostingContext property.
The following code example demonstrates how to use the ContextInformation type.
Imports System Imports System.Collections Imports System.Collections.Generic Imports System.Text Imports System.Configuration Imports System.Web Imports System.Web.Configuration Namespace Samples.Aspnet.ConfigurationSample Class UsingContextInformation Public Shared Sub Main() Try ' Set the path of the config file. Dim configPath As String = "" ' Get the Web application configuration object. Dim config As Configuration = _ WebConfigurationManager.OpenWebConfiguration(configPath) ' Get the section related object. Dim configSection As _ System.Web.Configuration.HealthMonitoringSection = _ CType(config.GetSection("system.web/healthMonitoring"), _ System.Web.Configuration.HealthMonitoringSection) ' Display title and info. Console.WriteLine("ASP.NET Configuration Info") Console.WriteLine() ' Display Config details. Console.WriteLine("File Path: {0", _ config.FilePath) Console.WriteLine("Section Path: {0", _ configSection.SectionInformation.Name) ' IsMachineLevel property. Console.WriteLine("IsMachineLevel: {0", _ config.EvaluationContext.IsMachineLevel) ' Create an object based on HostingContext. Dim myWC As WebContext = _ config.EvaluationContext.HostingContext ' Use the WebContext object to determine ' the ApplicationLevel. Console.WriteLine("ApplicationLevel: {0", _ myWC.ApplicationLevel) Catch e As System.Exception ' Error. Console.WriteLine(e.ToString()) End Try ' Display and wait. Console.ReadLine() End Sub End Class End Namespace
