Examples

The following example lists qualifier information about the Win32_Service class using the QualifierData class. For more information about Win32_Service, see the Windows Management Instrumentation documentation.

using System;
using System.Management;

public class Sample
{
    public static void Main()
    {
        // Get the WMI class
        ManagementClass mClass =
            new ManagementClass("Win32_Service");

        mClass.Options.UseAmendedQualifiers = true;

        // Get the Qualifiers for the class
        QualifierDataCollection qualifiers =
            mClass.Qualifiers;

        // display the Qualifier names
        Console.WriteLine(mClass.ClassPath.ClassName +
            " Qualifiers: ");
        foreach (QualifierData q in qualifiers)
        {
            Console.WriteLine(q.Name);
        }
        Console.WriteLine();

        Console.WriteLine("Class Description: ");
        Console.WriteLine(
            mClass.Qualifiers["Description"].Value);

Properties

Count	Gets the number of QualifierData objects in the QualifierDataCollection.
IsSynchronized	Gets a value indicating whether the object is synchronized (thread-safe).
Item[String]	Gets the specified QualifierData from the QualifierDataCollection.
SyncRoot	Gets the object to be used for synchronization.

Methods

Add(String, Object, Boolean, Boolean, Boolean, Boolean)	Adds a QualifierData to the QualifierDataCollection. This overload specifies all property values for a QualifierData.
Add(String, Object)	Adds a QualifierData to the QualifierDataCollection. This overload specifies the qualifier name and value.
CopyTo(Array, Int32)	Copies the QualifierDataCollection into an array.
CopyTo(QualifierData[], Int32)	Copies the QualifierDataCollection into a specialized QualifierData array.
Equals(Object)	Determines whether the specified object is equal to the current object. (Inherited from Object)
GetEnumerator()	Returns an enumerator for the QualifierDataCollection. This method is strongly typed.
GetHashCode()	Serves as the default hash function. (Inherited from Object)
GetType()	Gets the Type of the current instance. (Inherited from Object)
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
Remove(String)	Removes a QualifierData from the QualifierDataCollection by name.
ToString()	Returns a string that represents the current object. (Inherited from Object)

Explicit Interface Implementations

IEnumerable.GetEnumerator()

Returns an IEnumerator that iterates through the QualifierDataCollection.

Extension Methods

Cast<TResult>(IEnumerable)	Casts the elements of an IEnumerable to the specified type.
OfType<TResult>(IEnumerable)	Filters the elements of an IEnumerable based on a specified type.
AsParallel(IEnumerable)	Enables parallelization of a query.
AsQueryable(IEnumerable)	Converts an IEnumerable to an IQueryable.
