EntityFunctions.DiffNanoseconds Method

Definition

Namespace:

System.Data.Entity.Core.Objects

Assembly:

EntityFramework.dll

Overloads

DiffNanoseconds(Nullable<DateTimeOffset>, Nullable<DateTimeOffset>)	When used as part of a LINQ to Entities query, this method invokes the canonical DiffNanoseconds EDM function to calculate the number of nanoseconds between two date/times.
DiffNanoseconds(Nullable<TimeSpan>, Nullable<TimeSpan>)	When used as part of a LINQ to Entities query, this method invokes the canonical DiffNanoseconds EDM function to calculate the number of nanoseconds between two time spans.
DiffNanoseconds(Nullable<DateTime>, Nullable<DateTime>)	When used as part of a LINQ to Entities query, this method invokes the canonical DiffNanoseconds EDM function to calculate the number of nanoseconds between two date/times.

Public Shared Function DiffNanoseconds (timeValue1 As Nullable(Of DateTimeOffset), timeValue2 As Nullable(Of DateTimeOffset)) As Nullable(Of Integer)

Parameters

timeValue1

Nullable<DateTimeOffset>

The first date/time.

timeValue2
