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.

Return Value

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

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