public class QualifierDataCollection : ICollection, IEnumerable

NameDescription
System_CAPS_pubpropertyCount

Gets the number of QualifierData objects in the QualifierDataCollection.

System_CAPS_pubpropertyIsSynchronized

Gets a value indicating whether the object is synchronized.

System_CAPS_pubpropertyItem[String]

Gets the specified QualifierData from the QualifierDataCollection.

System_CAPS_pubpropertySyncRoot

Gets the object to be used for synchronization.

NameDescription
System_CAPS_pubmethodAdd(String, Object)

Adds a QualifierData to the QualifierDataCollection. This overload specifies the qualifier name and value.

System_CAPS_pubmethodAdd(String, Object, Boolean, Boolean, Boolean, Boolean)

Adds a QualifierData to the QualifierDataCollection. This overload specifies all property values for a QualifierData.

System_CAPS_pubmethodCopyTo(Array, Int32)

Copies the QualifierDataCollection into an array.

System_CAPS_pubmethodCopyTo(QualifierData[], Int32)

Copies the QualifierDataCollection into a specialized QualifierData array.

System_CAPS_pubmethodEquals(Object)

Determines whether the specified object is equal to the current object.(Inherited from Object.)

System_CAPS_protmethodFinalize()

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)

System_CAPS_pubmethodGetEnumerator()

Returns an enumerator for the QualifierDataCollection. This method is strongly typed.

System_CAPS_pubmethodGetHashCode()

Serves as the default hash function. (Inherited from Object.)

System_CAPS_pubmethodGetType()

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_protmethodMemberwiseClone()

Creates a shallow copy of the current Object.(Inherited from Object.)

System_CAPS_pubmethodRemove(String)

System_CAPS_pubmethodToString()

Returns a string that represents the current object.(Inherited from Object.)

NameDescription
System_CAPS_pubinterfaceSystem_CAPS_privmethodIEnumerable.GetEnumerator()

Returns an IEnumerator that iterates through the QualifierDataCollection.

NameDescription
System_CAPS_pubmethodAsParallel()

Overloaded. Enables parallelization of a query.(Defined by ParallelEnumerable.)

System_CAPS_pubmethodAsQueryable()

Overloaded. Converts an IEnumerable to an IQueryable.(Defined by Queryable.)

System_CAPS_pubmethodCast<TResult>()

Casts the elements of an IEnumerable to the specified type.(Defined by Enumerable.)

System_CAPS_pubmethodOfType<TResult>()

Filters the elements of an IEnumerable based on a specified type.(Defined by Enumerable.)

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 in the MSDN Library at http://msdn.microsoft.com/library.

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);
    }
}
