DateTimeOffset.GreaterThan(DateTimeOffset, DateTimeOffset) Operator

Definition

Namespace:

System

Assembly:

System.Runtime.dll

Source:

DateTimeOffset.cs

Determines whether one specified DateTimeOffset object is greater than (or later than) a second specified DateTimeOffset object.

public:
 static bool operator >(DateTimeOffset left, DateTimeOffset right);

public static bool operator > (DateTimeOffset left, DateTimeOffset right);

static member ( > ) : DateTimeOffset * DateTimeOffset -> bool

Public Shared Operator > (left As DateTimeOffset, right As DateTimeOffset) As Boolean

Parameters

left

DateTimeOffset

The first object to compare.

right

DateTimeOffset

The second object to compare.

Returns

Boolean

true if the UtcDateTime value of left is later than the UtcDateTime value of right; otherwise, false.

Remarks

The GreaterThan method defines the operation of the greater than operator for DateTimeOffset objects. It enables code such as the following:

DateTimeOffset date1 = new DateTimeOffset(2007, 6, 3, 14, 45, 0,
             new TimeSpan(-7, 0, 0));
DateTimeOffset date2 = new DateTimeOffset(2007, 6, 3, 15, 45, 0,
             new TimeSpan(-6, 0, 0));
DateTimeOffset date3 = new DateTimeOffset(date1.DateTime,
             new TimeSpan(-6, 0, 0));
Console.WriteLine(date1 > date2);        // Displays False
Console.WriteLine(date1 > date3);        // Displays True

let date1 =
    DateTimeOffset(2007, 6, 3, 14, 45, 0, TimeSpan(-7, 0, 0))

let date2 =
    DateTimeOffset(2007, 6, 3, 15, 45, 0, TimeSpan(-6, 0, 0))

let date3 =
    DateTimeOffset(date1.DateTime, TimeSpan(-6, 0, 0))

printfn $"{date1 > date2}" // Displays False
printfn $"{date1 > date3}" // Displays True

Dim date1 As New DateTimeOffset(#6/3/2007 2:45PM#, _
             New TimeSpan(-7, 0, 0))
Dim date2 As New DateTimeOffset(#6/3/2007 3:45PM#, _
             New TimeSpan(-6, 0, 0))
Dim date3 As New DateTimeOffset(date1.DateTime, _
             New TimeSpan(-6, 0, 0))
Console.WriteLine(date1 > date2)        ' Displays False
Console.WriteLine(date1 > date3)        ' Displays True

Languages that do not support custom operators can call the Compare method instead. They can also call the GreaterThan method directly, as the following example shows.

Dim date1 As New DateTimeOffset(#6/3/2007 2:45PM#, _
             New TimeSpan(-7, 0, 0))
Dim date2 As New DateTimeOffset(#6/3/2007 3:45PM#, _
             New TimeSpan(-6, 0, 0))
Dim date3 As New DateTimeOffset(date1.DateTime, _
             New TimeSpan(-6, 0, 0))
Console.WriteLine(DateTimeOffset.op_GreaterThan(date1, date2))  ' Displays False
Console.WriteLine(DateTimeOffset.op_GreaterThan(date1, date3))  ' Displays True

Before evaluating the left and right operands, the operator converts both values to Coordinated Universal Time (UTC). The operation is equivalent to the following:

return left.UtcDateTime > right.UtcDateTime;

left.UtcDateTime > right.UtcDateTime

Return left.UtcDateTime > right.UtcDateTime

The equivalent method for this operator is DateTimeOffset.Compare(DateTimeOffset, DateTimeOffset)
