	Name	Description
	Append(Object)	Appends the field to the hash code calculation.
	AppendT(ICollectionT)	Appends the values in a collection field to the hash code calculation.
	AppendBase	Appends the result of the base.GetHashCode method.
	AppendManyT	Appends the values in a collection field to the hash code calculation.
	Equals	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Gets the hash code computed for the fields supplied to this object. (Overrides ObjectGetHashCode.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Remarks

This class allows you to add field to the hash code calculation in a fluent style.

This is a partial port of the Apache Commons HashCodeBuilder utility class.

Examples

Copy

class Foo 
{
    private int field1;
    private int[] field2;

    ...

    public override int GetHashCode()
    {
        return new HashCodeBuilder()
            .Append(field1)
            .AppendMany(field2)
            .GetHashCode();
    }
}
