Please give Google a try: http://www.google.co.uk/search?gcx=w&sourceid=chrome&ie=UTF-8&q=Parallel+Programming+in+.net+4.0[^]

In future, at least try a simple google search instead of asking a basic question. Otherwise you waste your time, and ours.

请求不明确，但并行编程与函数的参数及其返回无关.

The request is not clear, but parallel programming has nothing to do with argument of a function and its return.

示例代码:

Dim ds2 As New DataSet
Dim T1 As New Task(Of DataSet)((Function() FUNCTION_NAME(ARGUMENT)))
Dim T2 As New Task(Of DataSet)((Function() FUNCTION_NAME(ARGUMENT)))  
T1.Start()
T2.Start()      
ds2 = T1.Result 'DS from Function 
ds2 = T3.Result 'DS from Function
