# Accessing the WMI Provider Programmatically

## WMI Provider Overview  
 The namespace used to obtain information about [!INCLUDE[ssRSnoversion](../includes/ssrsnoversion-md.md)] in the code samples shown in this topic is the **System.Management** namespace, found in the [!INCLUDE[msCoName](../includes/msconame-md.md)] [!INCLUDE[dnprdnshort](../includes/dnprdnshort-md.md)]. The **System.Management** namespace provides a set of managed code classes through which [!INCLUDE[dnprdnshort](../includes/dnprdnshort-md.md)] applications can access and manipulate management information. For more information on using the Reporting Services WMI classes using the **System.Management** namespace, see "Accessing Management Information with System.Managment" in the [!INCLUDE[msCoName](../includes/msconame-md.md)] [!INCLUDE[dnprdnshort](../includes/dnprdnshort-md.md)] SDK.  
  
## Finding a Report Server Instance  
 The preferred way of finding information on your report server installations is to enumerate through the WMI instance collection. The example below shows how to find properties on every report server instance by creating a collection, and looping through the collection to display the properties.  
  
```vb  
Imports System  
Imports System.Management  
Imports System.IO  
  
Module Module1  
    Sub Main()  
        Const WmiNamespace As String = "\\<ServerName>\root\Microsoft\SqlServer\ReportServer\<InstanceName>\v10\Admin"  
        Const WmiRSClass As String = _  
           "\\<ServerName>\root\Microsoft\SqlServer\ReportServer\<InstanceName>\v13\admin:MSReportServer_ConfigurationSetting"  
  
        Dim serverClass As ManagementClass  
        Dim scope As ManagementScope  
        scope = New ManagementScope(WmiNamespace)  
        'Connect to the Reporting Services namespace.  
        scope.Connect()  
  
        'Create the server class.  
        serverClass = New ManagementClass(WmiRSClass)  
        'Connect to the management object.  
        serverClass.Get()  
        If serverClass Is Nothing Then Throw New Exception("No class found")  
  
        'Loop through the instances of the server class.  
        Dim instances As ManagementObjectCollection = serverClass.GetInstances()  
        Dim instance As ManagementObject  
        For Each instance In instances  
            Console.Out.WriteLine("Instance Detected")  
            Dim instProps As PropertyDataCollection = instance.Properties  
            Dim prop As PropertyData  
            For Each prop In instProps  
                Dim name As String = prop.Name  
                Dim val As Object = prop.Value  
                Console.Out.Write("Property Name: " + name)  
                If val Is Nothing Then  
                    Console.Out.WriteLine("     Value: <null>")  
                Else  
                    Console.Out.WriteLine("     Value: " + val.ToString())  
                End If  
            Next  
        Next  
  
        Console.WriteLine("--- Press any key ---")  
        Console.ReadKey()  
  
    End Sub  
End Module  
```  
  
```csharp  
using System;  
using System.Management;  
using System.IO;  
[assembly: CLSCompliant(true)]  
  
class Class1  
{  
    [STAThread]  
    static void Main(string[] args)  
    {  
        const string WmiNamespace = @"\\<ServerName>\root\Microsoft\SqlServer\ReportServer\<InstanceName>\v10\Admin";  
        const string WmiRSClass =  
          @"\\<ServerName>\root\Microsoft\SqlServer\ReportServer\<InstanceName>\v13\admin:MSReportServer_ConfigurationSetting";  
        ManagementClass serverClass;  
        ManagementScope scope;  
        scope = new ManagementScope(WmiNamespace);  
  
        // Connect to the Reporting Services namespace.  
        scope.Connect();  
        // Create the server class.  
        serverClass = new ManagementClass(WmiRSClass);  
        // Connect to the management object.  
        serverClass.Get();  
        if (serverClass == null)  
            throw new Exception("No class found");  
  
        // Loop through the instances of the server class.  
        ManagementObjectCollection instances = serverClass.GetInstances();  
  
        foreach (ManagementObject instance in instances)  
        {  
            Console.Out.WriteLine("Instance Detected");  
            PropertyDataCollection instProps = instance.Properties;  
            foreach (PropertyData prop in instProps)  
            {  
                string name = prop.Name;  
                object val = prop.Value;  
                Console.Out.Write("Property Name: " + name);  
                if (val != null)  
                    Console.Out.WriteLine("     Value: " + val.ToString());  
                else  
                    Console.Out.WriteLine("     Value: <null>");  
            }  
        }  
        Console.WriteLine("\n--- Press any key ---");  
        Console.ReadKey();  
    }  
}  
```
