| GetType | Gets the Type of the current instance. (Inherited from Object) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object) |
| Reset | Reset all Counters |
| ToString | A string representation of this EndCriteria. (Overrides ObjectToString) |
| ToString(IFormatProvider) | A string representation of this EndCriteria. |
| ToString(String) | A string representation of this EndCriteria. |
| ToString(String, IFormatProvider) | A string representation of this EndCriteria. |
