Counts the number of nanosecond boundaries between two specified dates.
Overloads
| DateDiffNanosecond(Nullable<DateTimeOffset>, Nullable<DateTimeOffset>) |
Counts the number of nanosecond boundaries between two nullable dates. |
| DateDiffNanosecond(Nullable<DateTime>, Nullable<DateTime>) |
Counts the number of nanosecond boundaries between two nullable dates. |
| DateDiffNanosecond(DateTime, DateTime) |
Counts the number of nanosecond boundaries between two non-nullable dates. |
| DateDiffNanosecond(DateTimeOffset, DateTimeOffset) |
Counts the number of nanosecond boundaries between two non-nullable dates. |
Counts the number of nanosecond boundaries between two nullable dates.
public:
static Nullable<int> DateDiffNanosecond(Nullable<DateTimeOffset> startDate, Nullable<DateTimeOffset> endDate);public static int? DateDiffNanosecond(DateTimeOffset? startDate, DateTimeOffset? endDate);static member DateDiffNanosecond : Nullable<DateTimeOffset> * Nullable<DateTimeOffset> -> Nullable<int>Public Shared Function DateDiffNanosecond (startDate As Nullable(Of DateTimeOffset), endDate As Nullable(Of DateTimeOffset)) As Nullable(Of Integer)Parameters
- startDate
- Nullable<DateTimeOffset>
The start date for the time period.
- endDate
- Nullable<DateTimeOffset>
The end date for the time period.
Returns
When both parameters are not null, returns the number of nanosecond boundaries between the two specified dates. When one or both parameters are null, returns a null value.
Remarks
Corresponds to the SQL Server DATEDIFF function using nanosecond to specify the type of time boundary crossed. For more about this SQL Server function, see DATEDIFF.
