Equals(obj)
Summary
Indicates whether this instance and a specified object are equal.
Returns
true if obj and this instance are the same type and represent the same value; otherwise, false.
Parameters
| Name | Type | Description |
|---|---|---|
| obj | System.Object | The KeyWrapper<TKey> instance to compare with. |
GetHashCode()
Summary
Returns a hash code for this instance.
Returns
A hash code for this instance, suitable for use in hashing algorithms and data structures like a hash table.
