Methods

CompareTo(DateTimeNanos)

Compares the current instance with another object of the same type and returns an integer that indicates whether the current instance precedes, follows, or occurs in the same position in the sort order as the other object.

public int CompareTo(DateTimeNanos other)

Parameters

other DateTimeNanos

An object to compare with this instance.

Returns

int

A value that indicates the relative order of the objects being compared. The return value has these meanings:

Value	Meaning
Less than zero	This instance precedes other in the sort order.
Zero	This instance occurs in the same position in the sort order as other.
Greater than zero	This instance follows other in the sort order.

CompareTo(object?)

Compares the current instance with another object of the same type and returns an integer that indicates whether the current instance precedes, follows, or occurs in the same position in the sort order as the other object.

public int CompareTo(object? obj)

Parameters

obj object

An object to compare with this instance.

Returns

int

A value that indicates the relative order of the objects being compared. The return value has these meanings:

Value	Meaning
Less than zero	This instance precedes obj in the sort order.
Zero	This instance occurs in the same position in the sort order as obj.
Greater than zero	This instance follows obj in the sort order.

Exceptions

ArgumentException

obj is not the same type as this instance.

Equals(DateTimeNanos)

Indicates whether the current object is equal to another object of the same type.

public bool Equals(DateTimeNanos other)

Parameters

other DateTimeNanos

An object to compare with this object.

Returns

bool

true if the current object is equal to the other parameter; otherwise, false.

Equals(object?)

Indicates whether this instance and a specified object are equal.

public override bool Equals(object? obj)

Parameters

obj object

The object to compare with the current instance.

Returns

bool

true if obj and this instance are the same type and represent the same value; otherwise, false.

FromDotnetTicks(long)

Make a new DateTimeNanos object from a specified dotnet ticks value

public static DateTimeNanos FromDotnetTicks(long dotnetTicks)

Parameters

dotnetTicks long

Returns

DateTimeNanos

GetHashCode()

Returns the hash code for this instance.

public override int GetHashCode()

Returns

int

A 32-bit signed integer that is the hash code for this instance.

ToString()

Converts this DateTimeNanos object to a string using a default formatting string with nanosecond precision and the current culture's formatting conventions.

public override string ToString()

Returns

string

String representation of this DateTimeNanos object

ToString(string?, IFormatProvider?)

Converts this DateTimeNanos object to a string using the specified format and culture-specific format information.

public string ToString(string? format, IFormatProvider? formatProvider = null)

Parameters

format string

A standard or custom format string. This supports dotnet DateTime format specifiers with the addition of "fffffffff" for the number of nanoseconds when using a custom format. If null, a default formatting string with nanosecond precision is used.

formatProvider IFormatProvider

An object that supplies culture-specific formatting information. If null, the current culture's formatting conventions are used.

Returns

string

String representation of this DateTimeNanos object
