Question

c#对象实例化的对象如何在另一个事件中调用

public void Form1_Load(object sender, EventArgs e)
{
int port = 8089;
string host = "192.168.1.116";
IPAddress ip = IPAddress.Parse(host);
IPEndPoint ipe = new IPEndPoint(ip, port);
Socket c = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
c.Connect(ipe);

}

private void button1_Click(object sender, EventArgs e)
{

string sendStr = "hello!This is a socket test";
byte[] bs = Encoding.ASCII.GetBytes(sendStr);
c.Send(bs, bs.Length, 0);

}
在一个窗体下这个对象c想被多个事件中使用 但是提示
错误 1 当前上下文中不存在名称“c”
请高手给想个什么办法解决！

Socket c =null;
public void Form1_Load(object sender, EventArgs e)
        {
            int port = 8089;
            string host = "192.168.1.116";
            IPAddress ip = IPAddress.Parse(host);
            IPEndPoint ipe = new IPEndPoint(ip, port);
            c = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
            c.Connect(ipe);
        }
        private void button1_Click(object sender, EventArgs e)
        {
            string sendStr = "hello!This is a socket test";
            byte[] bs = Encoding.ASCII.GetBytes(sendStr);
            c.Send(bs, bs.Length, 0);
        }
