示例1: Main
' 导入命名空间
Imports System.IO
Imports System.Threading.Tasks
Module Example
Public Sub Main()
Dim tasks(1) As Task
Dim files() As String = Nothing
Dim dirs() As String = Nothing
Dim docsDirectory As String = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments)
tasks(0) = Task.Factory.StartNew( Sub()
files = Directory.GetFiles(docsDirectory)
End Sub )
tasks(1) = Task.Factory.StartNew( Sub()
dirs = Directory.GetDirectories(docsDirectory)
End Sub )
Task.Factory.ContinueWhenAll(tasks, Sub(completedTasks)
Console.WriteLine("{0} contains: ", docsDirectory)
Console.WriteLine(" {0} subdirectories", dirs.Length)
Console.WriteLine(" {0} files", files.Length)
End Sub)
End Sub
End Module输出：
C:\Users\\Documents contains: 24 subdirectories 16 files
