IFilterCriteria Interface

System Center
Use the IFilterCriteria interface to programmatically access to a single filter condition.

Namespace: Microsoft.SystemCenter.Orchestrator.Integration
Assembly: Microsoft.SystemCenter.Orchestrator.Integration (in Microsoft.SystemCenter.Orchestrator.Integration.dll)

Dim instance As IFilterCriteria

public interface IFilterCriteria
public interface IFilterCriteria
public interface IFilterCriteria

public SelectQuery GetSelectQueryFrom(IActivityRequest request)
    StringBuilder conditions = new StringBuilder();
    foreach (IFilterCriteria filter in request.Filters)
        if (conditions.Length != 0)     
            conditions.Append(" AND "); 


        switch (filter.Relation)
           case Relation.EqualTo:

            case Relation.NotEqualTo:

            // ...

        conditions.AppendFormat("'{0}'", filter.Value.AsString);

    string className = request.Inputs["Class Name"].AsString;
    return SelectQuery(className, conditions);

The IFilterCriteria interface will typically be used by those Activity classes that require customized querying solutions beyond the filtering support provided by IActivityRequest.
