Filter group in C#

IIRC, you need to create an EntitySchemaQueryFilterCollection and then populate it with another EntitySchemaQueryFilterCollection for the nested Or. Something like this, but going off top of my head - hopefully this gets you close:

// create filter collection with And
var filterGroup = new EntitySchemaQueryFilterCollection(esq, LogicalOperationStrict.And);
 
// add CreatedOn filter
filterGroup.Add(esq.CreateFilterWithParameters(FilterComparisonType.GreaterOrEqual, "CreatedOn", ThreeHoursAgo));
 
// add another filter collection for Status with Or
filterGroup.Add(new EntitySchemaQueryFilterCollection(esq, LogicalOperationStrict.Or) {
    esq.CreateFilterWithParameters(FilterComparisonType.Equal, "Status.Text", "Complete"),
    esq.CreateFilterWithParameters(FilterComparisonType.Equal, "Status.Text", "Pending")
});
 
// now add filter collection to esq
esq.Filters.Add(filterGroup);

EntitySchemaQuery esqResult = new EntitySchemaQuery(userConnection.EntitySchemaManager, "YourEntityHere");
 
esqResult.AddColumn("CreatedOn ");
esqResult.AddColumn("Status ");
 
Guid StatusComplete = Guid.Parse("XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX"); // insert your guid
Guid StatusPending = Guid.Parse("XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX"); // insert your guid
 
//Status Filter
esqResult.Filters.Add(
    new EntitySchemaQueryFilterCollection(
        esqResult,
        Terrasoft.Common.LogicalOperationStrict.Or,
        esqResult.CreateFilterWithParameters(FilterComparisonType.Equal, "Status", StatusComplete),
        esqResult.CreateFilterWithParameters(FilterComparisonType.Equal, "Status", StatusPending)
        )
    );
 
//Date Filter
TimeZoneInfo userTimeZonInfo = userConnection.CurrentUser.TimeZone;
DateTime createdOn = TimeZoneInfo.ConvertTimeToUtc(activity.GetTypedColumnValue<DateTime>("CreatedOn"), userTimeZonInfo);
DateTime ThreeHoursAgo = DateTime.Now.AddHours(-3);
 
 
var dateFilter = new EntitySchemaQueryFilterCollection(
    esqResult,
    Terrasoft.Common.LogicalOperationStrict.And,
    esqResult.CreateFilterWithParameters(FilterComparisonType.GreaterOrEqual, "CreatedOn", ThreeHoursAgo)
);
 
esqResult.Filters.Add(
    new EntitySchemaQueryFilterCollection(
        esqResult,
        Terrasoft.Common.LogicalOperationStrict.And,
        dateFilter1,
    )
);
EntityCollection entitites = esqResult.GetEntityCollection(userConnection);
