JScript does not support generic types and methods.

Type Parameters

  • TLeft
    The type of left.

  • TRight
    The type of right.

  • TLeftDuration
    The type of left duration.

  • TRightDuration
    The type of right duration.

  • TResult
    The type of result.

Parameters

Return Value

Type: System.Reactive.Linq.IQbservable<TResult>
A queryable observable sequence that contains result elements computed from source elements that have an overlapping duration.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type IQbservable<TLeft>. When you use instance method syntax to call this method, omit the first parameter. For more information, see or .
