EntityFunctions.DiffMicroseconds Method

Definition

Namespace:

System.Data.Entity.Core.Objects

Assembly:

EntityFramework.dll

Overloads

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