Parameters

source1: Type: System.Linq IQueryable T1
The first input dataset

source2: Type: System.Linq IQueryable T2
The second input dataset

procFunc: Type: System.Linq.Expressions Expression Func T1, T2, T3
The function to apply to each pair of the cross product

Type Parameters

T1: The type of the records of dataset source1
T2: The type of the records of dataset source2
T3: The type of the records of the result dataset

Return Value

Type: IQueryable T3
The output dataset

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).
