C# send data from Windows Forms to WCF service

Question

Can i send a List from windows form to a wcf service? I'm using wcf web service. I'm reading from a file in form and i want to send result to service.

StreamReader file = new StreamReader(File.OpenRead(ofd.FileName));
List<string> lines = new List<string>();
List<double> fileResult = new List<double>();
while(!file.EndOfStream)
{
    var line = file.ReadLine();
    lines.Add(line);

}
file.Close();

for (int i = 0; i < lines.Count; i++)                
{                
    fileResult.Add(Convert.ToDouble(lines[i]));                   
}

Yes, you can.

However, you'll want to send/receive it either as an IEnumerable<double> or a double[]
