	IQueryable<T>^ source, 
	Func<IQueryable<T>^, IQueryable<T>^>^ body, 
	Func<IQueryable<T>^, IQueryable<T>^, IQueryable<bool>^>^ cond
)

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
cond: Type: System.Func<IQueryable<T>, IQueryable<T>, IQueryable<Boolean>>
The termination condition of the DoWhile loop

Type Parameters

T: The type of the input records

Return Value

Type: IQueryable<T>
The output dataset

Usage Note
