c# - C#中的InitializeComponent不存在

我正在使用.net 4，但没有看到InitializeComponent方法。有吗

这是我正在使用的班级文件

using System;

    private System.ComponentModel.Container components = null;

    //default constructor

        InitializeComponent();

        readThread = new Thread(new ThreadStart(RunClient));
        readThread.Start();
    }

    [STAThread]
    static void Main()
    {
        Application.Run(new Client());

    protected void Client_Closing(object sender, CancelEventArgs e)

    }


    //sends text the user typed to server
    protected void inputText_KeyDown(object sender, KeyEventArgs e)
    {

        try

                inputTextBox.Clear();

        }

            //Step 1: create TcpClient and connect to server
            client = new TcpClient();
            client.Connect("localhost", 5000);

            //Step 2: Get NetworkStream associated with TcpClient
            output = client.GetStream();

            //creates objects for writing and reading across streams
            writer = new BinaryWriter(output);
            reader = new BinaryReader(output);

            displayTextBox.Text += "\r\nGot I/O stream\r\n";

            inputTextBox.ReadOnly = false;

            //loop until server signals termination
            do
            {

                //Step 3: processing phase
                try
                {
                    //read message from the server
                    message = reader.ReadString();
                    displayTextBox.Text += "\r\n" + message;
                }

                //handle exception if error in reading server data
                catch (Exception)
                {
                    System.Environment.Exit(System.Environment.ExitCode);
                }


            } while (message != "SERVER>>> TERMINATE");

            displayTextBox.Text += "\r\nClosing connection.\r\n";

            //Step 4: close connection
            writer.Close();
            reader.Close();
            output.Close();
            client.Close();
            Application.Exit();

        }
        catch (Exception error)
        {
            MessageBox.Show(error.ToString());
        }
    }

}

最佳答案

Control或其任何子级（如Form）未定义或抽象方法InitializeComponent；它是由设计师从头开始100％生成的。它也是私人的；您不能从控件类外部调用它。如果尚未从设计器开发此Control类，则除非您自己创建一个，否则就没有InitializeComponent方法。
