Parameters

source: Type: System.Linq IQueryable T
The input dataset

body: Type: System Func IQueryable T , IQueryable T
The code body of the DoWhile loop

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type IQueryable T . 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).
