C# listview add items
- by Eyla
Greetings,
I have a method to capture packets. after capturing I want to add each packet as a row in listview in runting time so as soon as I capture packet I want to add it to the list view.
the problem that when I use items.Add() I will get overload argument error.
please advice!!
here is my code:
private void packetCapturingThreadMethod()
{
Packet packet = null;
int countOfPacketCaptures = 0;
while ((packet = device.GetNextPacket()) != null)
{
packet = device.GetNextPacket();
if (packet is TCPPacket)
{
TCPPacket tcp = (TCPPacket)packet;
myPacket tempPacket = new myPacket();
tempPacket.packetType = "TCP";
tempPacket.sourceAddress = Convert.ToString(tcp.SourceAddress);
tempPacket.destinationAddress = Convert.ToString(tcp.DestinationAddress);
tempPacket.sourcePort = Convert.ToString(tcp.SourcePort);
tempPacket.destinationPort = Convert.ToString(tcp.DestinationPort);
tempPacket.packetMessage = Convert.ToString(tcp.Data);
packetsList.Add(tempPacket);
string[] row = { packetsList[countOfPacketCaptures].packetType, packetsList[countOfPacketCaptures].sourceAddress, packetsList[countOfPacketCaptures].destinationAddress, packetsList[countOfPacketCaptures].sourcePort, packetsList[countOfPacketCaptures].destinationPort, packetsList[countOfPacketCaptures].packetMessage };
try {
listView1.Items.Add(packetsList[countOfPacketCaptures].packetType, packetsList[countOfPacketCaptures].sourceAddress, packetsList[countOfPacketCaptures].destinationAddress, packetsList[countOfPacketCaptures].sourcePort, packetsList[countOfPacketCaptures].destinationPort, packetsList[countOfPacketCaptures].packetMessage)
; countOfPacketCaptures++;
lblCapturesLabels.Text = Convert.ToString(countOfPacketCaptures);}
catch (Exception e) { }
}
else if (packet is UDPPacket)
{
UDPPacket udp = (UDPPacket)packet;
myPacket tempPacket = new myPacket();
tempPacket.packetType = "UDP";
tempPacket.sourceAddress = Convert.ToString(udp.SourceAddress);
tempPacket.destinationAddress = Convert.ToString(udp.DestinationAddress);
tempPacket.sourcePort = Convert.ToString(udp.SourcePort);
tempPacket.destinationPort = Convert.ToString(udp.DestinationPort);
tempPacket.packetMessage = Convert.ToString(udp.Data);
packetsList.Add(tempPacket);
string[] row = { packetsList[countOfPacketCaptures].packetType, packetsList[countOfPacketCaptures].sourceAddress, packetsList[countOfPacketCaptures].destinationAddress, packetsList[countOfPacketCaptures].sourcePort, packetsList[countOfPacketCaptures].destinationPort, packetsList[countOfPacketCaptures].packetMessage };
try { dgwPacketInfo.Rows.Add(row);
countOfPacketCaptures++;
lblCapturesLabels.Text = Convert.ToString(countOfPacketCaptures);
}
catch (Exception e) { }
}
}
}
