## IEqualityComparer class


Interface providing means to compare two objects for equality. Objects of this class should only be allocated using [System::MakeObject()](../../system/makeobject/) function. Never create instance of this type on stack or using operator new, as it will result in runtime errors and/or assertion faults. Always wrap this class into [System::SmartPtr](../../system/smartptr/) pointer and use this pointer to pass it to functions as argument.

```cpp
template<typename T>class IEqualityComparer : public virtual System::Object
```


| Parameter | Description |
| --- | --- |
| T | Type being compared. |
## Methods

| Method | Description |
| --- | --- |
| virtual [Equals](./equals/)(T, T) const | RTTI information. |
| virtual [GetHashCode](./gethashcode/)(T) const | Gets hash code for some object. |
