 Retrieve View :

        QueryExpression mySavedQuery = new QueryExpression
        {
            ColumnSet = new ColumnSet("savedqueryid", "name", "querytype", "isdefault", "returnedtypecode", "isquickfindquery"),
            EntityName = SavedQuery.EntityLogicalName,
            Criteria = new FilterExpression
            {
                Conditions =
{
    new ConditionExpression
    {
        AttributeName = "querytype",
        Operator = ConditionOperator.Equal,
        Values = {0}
    },
    new ConditionExpression
    {
        AttributeName = "returnedtypecode",
        Operator = ConditionOperator.Equal,
        Values = {Opportunity.EntityTypeCode}
    }
}
            }
        };
        RetrieveMultipleRequest retrieveSavedQueriesRequest = new RetrieveMultipleRequest { Query = mySavedQuery };

        RetrieveMultipleResponse retrieveSavedQueriesResponse = (RetrieveMultipleResponse)_serviceProxy.Execute(retrieveSavedQueriesRequest);

        DataCollection<Entity> savedQueries = retrieveSavedQueriesResponse.EntityCollection.Entities;

        //Display the Retrieved views
        foreach (Entity ent in savedQueries)
        {
            SavedQuery rsq = (SavedQuery)ent;
            Console.WriteLine("{0} : {1} : {2} : {3} : {4} : {5},", rsq.SavedQueryId, rsq.Name, rsq.QueryType, rsq.IsDefault, rsq.ReturnedTypeCode, rsq.IsQuickFindQuery);
        }

Deactivate Views

If you do not want a public view to appear in the application, you can deactivate it. You cannot deactivate a public view that is set as the default view. The following sample deactivates the Closed Opportunities in Current Fiscal Year view for the Opportunity entity:

C#

System.String SavedQueryName = "Closed Opportunities in Current Fiscal Year";
QueryExpression ClosedOpportunitiesViewQuery = new QueryExpression
{
    ColumnSet = new ColumnSet("savedqueryid", "statecode", "statuscode"),
    EntityName = SavedQuery.EntityLogicalName,
    Criteria = new FilterExpression
    {
        Conditions =
        {
            new ConditionExpression
            {
                AttributeName = "querytype",
                Operator = ConditionOperator.Equal,
                Values = {0}
            },
            new ConditionExpression
            {
                AttributeName = "returnedtypecode",
                Operator = ConditionOperator.Equal,
                Values = {Opportunity.EntityTypeCode}
            },
                            new ConditionExpression
            {
                AttributeName = "name",
                Operator = ConditionOperator.Equal,
                Values = {SavedQueryName}
            }
        }
    }
};

RetrieveMultipleRequest retrieveOpportuntiesViewRequest = new RetrieveMultipleRequest { Query = ClosedOpportunitiesViewQuery };

RetrieveMultipleResponse retrieveOpportuntiesViewResponse = (RetrieveMultipleResponse)_serviceProxy.Execute(retrieveOpportuntiesViewRequest);

SavedQuery OpportunityView = (SavedQuery)retrieveOpportuntiesViewResponse.EntityCollection.Entities[0];
_viewOriginalState = (SavedQueryState)OpportunityView.StateCode;
_viewOriginalStatus = OpportunityView.StatusCode;


SetStateRequest ssreq = new SetStateRequest
{
    EntityMoniker = new EntityReference(SavedQuery.EntityLogicalName, (Guid)OpportunityView.SavedQueryId),
    State = new OptionSetValue((int)SavedQueryState.Inactive),
    Status = new OptionSetValue(2)
};
_serviceProxy.Execute(ssreq);
