struct System.HashCode
Assembly: System.Runtime
Combines the hash code for multiple values into a single hash code.
Methods
value
The span to add.
public
void
Add(T value)
Adds a single value to the hash code.
value
The value to add to the hash code.
public
void
Add(T value,
IEqualityComparer?<T> comparer)
Adds a single value to the hash code, specifying the type that provides the hash code function.
value
The value to add to the hash code.
comparer
The <see cref="T:System.Collections.Generic.IEqualityComparer`1" /> to use to calculate the hash code.
This value can be a null reference (Nothing in Visual Basic), which will use the default equality comparer for <typeparamref name="T" /> .
