Remarks

A group contains one or multiple filter conditions combined with an operator:

If the operator is OR, the group evaluates to true, that is the Match method of the group returns true, when at least one of its conditions is true.
If the operator is AND, the group evaluates to true, that is the Match method of the group returns true, when all its conditions are true.

An object is checked against the group by calling the Match method. If the Match() method returns true, the specified object is excluded from schema compare operations.

Example

The following code creates a group that is part of a view filter. The group excludes the views the name of which starts with "temp" or ends with "tmp":

EntityFilter viewFilter = new EntityFilter(SqlEntityTypeEnum.View);
EntityFilterGroup group = new EntityFilterGroup(viewFilter);
                        
// combines the conditions in the group with the OR operator
group.ConditionOperator = EntityFilterOperatorEnum.OR;
                        
// add the group conditions
group.Conditions.Add(new EntityNameFilterCondition("temp", EntityFilterConditionTypeEnum.StartingWith, group));
group.Conditions.Add(new EntityNameFilterCondition("tmp", EntityFilterConditionTypeEnum.EndingWith, group));
                        
viewFilter.Groups.Add(group);
