Constructors

Wrapper()

Initializes a new instance of the Wrapper<T> class.

protected Wrapper()

Wrapper(T)

Initializes a new instance of the Wrapper<T> class with the specified value.

protected Wrapper(T value)

Parameters

value T

The value to wrap.

Properties

HasValue

Gets a value indicating whether the wrapped value is not equal to the default value of type T.

public bool HasValue { get; }

Property Value

bool

IsDisposed

Gets a value indicating whether this instance has already been disposed.

public bool IsDisposed { get; }

Property Value

bool

Value

Gets or sets the wrapped value.

public virtual T Value { get; set; }

Property Value

T

Methods

Dispose()

Releases all resources used by the current instance.

public void Dispose()

DisposeManaged()

Releases managed resources used by the current instance.

protected virtual void DisposeManaged()

DisposeNative()

Releases unmanaged (native) resources used by the current instance.

~Wrapper()

Finalizes an instance of the Wrapper<T> class.

protected ~Wrapper()

GetHashCode()

Returns a hash code for this instance based on the wrapped value.

public override int GetHashCode()

Returns

int

A hash code for the current object.

OnEquals(Wrapper<T>)

Determines whether the wrapped value of this instance equals the wrapped value of another instance.

protected override bool OnEquals(Wrapper<T> other)

Parameters

other Wrapper<T>

Another instance of Wrapper<T> to compare with.

Returns

bool

true if the wrapped values are equal; otherwise, false.

ToString()

Returns a string that represents the current instance.

public override string ToString()

Returns

string

A string representation of the wrapped value, or an empty string if no value is present.

Operators

explicit operator T(Wrapper<T>)

Defines an explicit conversion operator from Wrapper<T> to T.

Parameters

wrapper Wrapper<T>

The wrapper instance.

Returns

T
