示例1: StringCopy
Delegate Sub StringCopy(stringArray1() As String, _
stringArray2() As String, _
indexToStart As Integer)
Module TestDelegate
Public Sub Main()
Dim ordinals() As String = {"First", "Second", "Third", "Fourth", "Fifth"}
Dim copiedOrdinals(ordinals.Length - 1) As String
Dim copyOperation As StringCopy = AddressOf CopyStrings
copyOperation(ordinals, copiedOrdinals, 3)
For Each ordinal As String In copiedOrdinals
Console.WriteLine(ordinal)
Next
End Sub
Private Sub CopyStrings(source() As String, target() As String, startPos As Integer)
If source.Length <> target.Length Then
Throw New IndexOutOfRangeException("The source and target arrays must have the same number of elements.")
End If
For ctr As Integer = startPos to source.Length - 1
target(ctr) = String.Copy(source(ctr))
Next
End Sub
End Module示例2: TestAction3
Module TestAction3
Public Sub Main()
Dim ordinals() As String = {"First", "Second", "Third", "Fourth", "Fifth"}
Dim copiedOrdinals(ordinals.Length - 1) As String
Dim copyOperation As Action(Of String(), String(), Integer) = AddressOf CopyStrings
copyOperation(ordinals, copiedOrdinals, 3)
For Each ordinal As String In copiedOrdinals
Console.WriteLine(ordinal)
Next
End Sub
Private Sub CopyStrings(source() As String, target() As String, startPos As Integer)
If source.Length <> target.Length Then
Throw New IndexOutOfRangeException("The source and target arrays must have the same number of elements.")
End If
For ctr As Integer = startPos to source.Length - 1
target(ctr) = String.Copy(source(ctr))
Next
End Sub
End Module示例3: TestLambda
Public Module TestLambda
Public Sub Main()
Dim ordinals() As String = {"First", "Second", "Third", "Fourth", "Fifth"}
Dim copiedOrdinals(ordinals.Length - 1) As String
Dim copyOperation As Action(Of String(), String(), Integer) = _
Sub(s1, s2, pos) CopyStrings(s1, s2, pos)
copyOperation(ordinals, copiedOrdinals, 3)
For Each ordinal As String In copiedOrdinals
If String.IsNullOrEmpty(ordinal) Then
Console.WriteLine("<None>")
Else
Console.WriteLine(ordinal)
End If
Next
End Sub
Private Function CopyStrings(source() As String, target() As String, startPos As Integer) As Integer
If source.Length <> target.Length Then
Throw New IndexOutOfRangeException("The source and target arrays must have the same number of elements.")
End If
For ctr As Integer = startPos To source.Length - 1
target(ctr) = String.Copy(source(ctr))
Next
Return source.Length - startPos
End Function
End Module输出：
Fourth Fifth
