Parameters

source: Type: System.Linq IQueryable T1
The first input dataset

otherSources: Type: System.Linq IQueryable T1
Other input datasets

applyFunc: Type: System.Linq.Expressions Expression Func IEnumerable T1 , IEnumerable T2
The function to be applied to the input datasets

isFirstOnly (Optional): Type: System Boolean
True if only distributive over the first dataset

Type Parameters

T1: The type of the records of input
T2: The type of the records of output

Return Value

Type: IQueryable T2
The result of computing applyFunc(source, otherSources)

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type IQueryable T1 . When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).
