Syntax

public IEnumerable<CimInstance> QueryInstances(
    string namespaceName,
    string queryDialect,
    string queryExpression,
    CimOperationOptions options
)

public:
IEnumerable<CimInstance^>^ QueryInstances(
    String^ namespaceName,
    String^ queryDialect,
    String^ queryExpression,
    CimOperationOptions^ options
)

member QueryInstances : 
        namespaceName:string *
        queryDialect:string *
        queryExpression:string *
        options:CimOperationOptions -> IEnumerable<CimInstance>

Public Function QueryInstances (
    namespaceName As String,
    queryDialect As String,
    queryExpression As String,
    options As CimOperationOptions
) As IEnumerable(Of CimInstance)

Parameters

• namespaceName
  Type: System.String

  A null-terminated string that contains the optional namespace name to carry out the operation. If none is specified, the server will pick a default. The namespace cannot include a computer name. It can only be in the form of a namespace name separated by a slash mark character (/). For example, the following would be a valid namespaceName value: root/cimv2.

• queryDialect
  Type: System.String

  A string that contains the dialect of the query being passed. This value can be either WQL or CQL. Note that some servers do not support all query types.

• queryExpression
  Type: System.String

  A string that contains the query expression to be carried out. Usually a query is needed, but if a WS-Management endpoint is being used, a resource URI can be passed. For WMI DCOM transport, this value must be specified.

• options
  Type: Microsoft.Management.Infrastructure.Options.CimOperationOptions

  A CimOperationOptions object that specifies options, such as timeouts, and how to control the CIM semantics.

Return Value

Type: System.Collections.Generic.IEnumerable<CimInstance>

An IEnumerable<T> interface that can be used to enumerate the instances.
