RelationshipQuery Constructors

Definition

Namespace:

System.Management

Assembly:

System.Management.dll

Package:

System.Management v9.0.0

Initializes a new instance of the RelationshipQuery class.

Overloads

RelationshipQuery()	Initializes a new instance of the RelationshipQuery class. This is the parameterless constructor.
RelationshipQuery(String)	Initializes a new instance of the RelationshipQuery class. If the specified string can be successfully parsed as a WQL query, it is considered to be the query string; otherwise, it is assumed to be the path of the source object for the query. In this case, the query is assumed to be an instances query.
RelationshipQuery(String, String)	Initializes a new instance of the RelationshipQuery class for the given source object and relationship class. The query is assumed to be an instance query (as opposed to a schema query).
RelationshipQuery(Boolean, String, String, String, String)	Initializes a new instance of the RelationshipQuery class for a schema query using the given set of parameters. This constructor is used for schema queries only, so the first parameter must be true.
RelationshipQuery(String, String, String, String, Boolean)	Initializes a new instance of the RelationshipQuery class for the given set of parameters. The query is assumed to be an instance query (as opposed to a schema query).

RelationshipQuery()

Source:

ManagementQuery.cs

Initializes a new instance of the RelationshipQuery class. This is the parameterless constructor.

public:
 RelationshipQuery();

public RelationshipQuery ();

Public Sub New ()

Remarks

.NET Framework Security

Full trust for the immediate caller. This member cannot be used by partially trusted code. For more information, see Using Libraries from Partially Trusted Code.

RelationshipQuery(String)

Source:

ManagementQuery.cs

Initializes a new instance of the RelationshipQuery class. If the specified string can be successfully parsed as a WQL query, it is considered to be the query string; otherwise, it is assumed to be the path of the source object for the query. In this case, the query is assumed to be an instances query.

public:
 RelationshipQuery(System::String ^ queryOrSourceObject);

public RelationshipQuery (string queryOrSourceObject);

new System.Management.RelationshipQuery : string -> System.Management.RelationshipQuery

Public Sub New (queryOrSourceObject As String)

Parameters

queryOrSourceObject

String

The query string or the class name for this query.

Examples

The following example sets the type of relationship between a WMI class and a RelatedObjectQuery.

using System;
using System.Management;

class Sample
{
    public static void Main(string[] args)
    {
        // Full query string is specified
        // to the constructor
        RelationshipQuery q =
            new RelationshipQuery(
            "references of {Win32_ComputerSystem.Name='mymachine'}");

        // Only the object of interest is
        // specified to the constructor
        RelationshipQuery query =
            new RelationshipQuery("Win32_Service.Name='Alerter'");
    }
}

Imports System.Management


Public Class Sample
    Public Overloads Shared Function _
        Main(ByVal args() As String) As Integer

        ' Full query string is specified
        ' to the constructor
        Dim q As New RelationshipQuery( _
            "references of {Win32_ComputerSystem.Name='mymachine'}")

        ' Only the object of interest is
        ' specified to the constructor
        Dim query As New RelationshipQuery( _
            "Win32_Service.Name='Alerter'")

    End Function
End Class

RelationshipQuery(String, String)

Source:

ManagementQuery.cs

Initializes a new instance of the RelationshipQuery class for the given source object and relationship class. The query is assumed to be an instance query (as opposed to a schema query).

public:
 RelationshipQuery(System::String ^ sourceObject, System::String ^ relationshipClass);

public RelationshipQuery (string sourceObject, string relationshipClass);

new System.Management.RelationshipQuery : string * string -> System.Management.RelationshipQuery

Public Sub New (sourceObject As String, relationshipClass As String)

Parameters

sourceObject

String

The path of the source object for this query.

relationshipClass

String

The type of relationship for which to query.

RelationshipQuery(Boolean, String, String, String, String)

Source:

ManagementQuery.cs

Initializes a new instance of the RelationshipQuery class for a schema query using the given set of parameters. This constructor is used for schema queries only, so the first parameter must be true.

public:
 RelationshipQuery(bool isSchemaQuery, System::String ^ sourceObject, System::String ^ relationshipClass, System::String ^ relationshipQualifier, System::String ^ thisRole);

public RelationshipQuery (bool isSchemaQuery, string sourceObject, string relationshipClass, string relationshipQualifier, string thisRole);

new System.Management.RelationshipQuery : bool * string * string * string * string -> System.Management.RelationshipQuery

Public Sub New (isSchemaQuery As Boolean, sourceObject As String, relationshipClass As String, relationshipQualifier As String, thisRole As String)

Parameters

isSchemaQuery

Boolean

true to indicate that this is a schema query; otherwise, false.

sourceObject

String

The path of the source class for this query.

relationshipClass

String

The type of relationship for which to query.

relationshipQualifier

String

A qualifier required to be present on the relationship class.

thisRole

String

The role that the source class is required to play in the relationship.

RelationshipQuery(String, String, String, String, Boolean)

Source:

ManagementQuery.cs

Initializes a new instance of the RelationshipQuery class for the given set of parameters. The query is assumed to be an instance query (as opposed to a schema query).

public:
 RelationshipQuery(System::String ^ sourceObject, System::String ^ relationshipClass, System::String ^ relationshipQualifier, System::String ^ thisRole, bool classDefinitionsOnly);

public RelationshipQuery (string sourceObject, string relationshipClass, string relationshipQualifier, string thisRole, bool classDefinitionsOnly);

new System.Management.RelationshipQuery : string * string * string * string * bool -> System.Management.RelationshipQuery

Public Sub New (sourceObject As String, relationshipClass As String, relationshipQualifier As String, thisRole As String, classDefinitionsOnly As Boolean)

Parameters

sourceObject

String

The path of the source object for this query.

relationshipClass

String

The type of relationship for which to query.

relationshipQualifier

String

A qualifier required to be present on the relationship object.

thisRole

String

The role that the source object is required to play in the relationship.

classDefinitionsOnly

Boolean

When this method returns, it contains a Boolean that indicates that only class definitions for the resulting objects are returned.
