Question Converting a C# Lambda expression to VB.NET

[njsokalski]

I will probably sound like a bad developer here, but I am attempting to convert some code from the following page from C# to VB.NET:

http://msdn.microsoft.com/en-us/library/hh286407(v=VS.92).aspx

The code I am having trouble converting is from Step 4 of "Joining a Multicast Group" on the page, and here is the code with the comment lines removed:

private void Join()
{
_receiveBuffer = new byte[MAX_MESSAGE_SIZE];
_client = new UdpAnySourceMulticastClient(IPAddress.Parse(GROUP_ADDRESS), GROUP_PORT);
_client.BeginJoinGroup(
result =>
{
_client.EndJoinGroup(result);
_client.MulticastLoopback = true;
_joined = true;
Send("Joined the group");
Receive();
}, null);
}

Any help would be greatly appreciated. Thanks.

Conversion of C# lambdas to VB lambdas is quite simple. This:

arg => returnValue

becomes this:

Function(arg) returnValue

while this:

arg => action

becomes this:

Sub(arg) action

In that case the lambda doesn't return anything so you would use Sub rather than Function. Also, that is a multine lambda, which would look like this in VB:

Function(arg)
    Return returnValue
End Function

Sub(arg)
    action
End Sub
