C＃中的VB.NET委托

Question

I'm trying to convert this working .NET2 C# into .NET2 VB.NET, using NUnit 2.6.4

[Test]
public void Test() {
    Assert.Throws<Exception>(delegate {
        DoSomething(2);
    });
}

public void DoSomething(int i) {
    throw new Exception();
}

then into VB:

<Test> _
Public Sub Test()
    Assert.Throws(Of Exception)(Sub() DoSomething(2))
End Sub

Public Sub DoSomething(i As Integer)
    Throw New Exception()
End Sub

this works in .NET4 but not .NET2 - as I'm using an anonymous method... but how to express a delegate in .NET2 in VB.NET

Something like: AddressOf DoSomething(2)

Answer 1

You can create a new named method, rather than using an anonymous method.

Public Sub Test()
    Assert.Throws(Of Exception)(AddressOf DoSomethingPassingTwo)
End Sub

Public Sub DoSomethingPassingTwo()
    DoSomething(2)
End Sub

Public Sub DoSomething(i As Integer)
    Throw New Exception()
End Sub
