Sample: Using the WMI Event Provider with the .NET Framework
The following sample creates an application in C# that uses the WMI Event Provider to return event data for all data definition language (DDL) events that occur on a default installation instance of SQL Server.
Example
The example compiles by using the following command file:
set compiler_path=C:\WINNT\Microsoft.NET\Framework\v2.0.50110
%compiler_path%\csc %1
using System;
using System.Management;
class SQLWEPExample
{
public static void Main(string[] args)
{
string query = @"SELECT * FROM DDL_EVENTS " ;
// Default namespace for default instance of SQL Server
string managementPath =
@"\\.\root\Microsoft\SqlServer\ServerEvents\MSSQLSERVER";
ManagementEventWatcher watcher =
new ManagementEventWatcher(new WqlEventQuery (query));
ManagementScope scope = new ManagementScope (managementPath);
scope.Connect();
watcher.Scope = scope;
Console.WriteLine("Watching...");
while (true)
{
ManagementBaseObject obj = watcher.WaitForNextEvent();
Console.WriteLine("Event!");
foreach (PropertyData data in obj.Properties)
{
Console.Write("{0}:", data.Name);
if (data.Value == null)
{
Console.WriteLine("<null>");
}
else
{
Console.WriteLine(data.Value.ToString());
}
}
Console.WriteLine("-----");
Console.WriteLine();
Console.WriteLine();
}
}
}
