禁用c#套接字中的按钮

我在c#中创建了两个按钮。如果另一个按钮的功能出了问题，有没有办法使按钮失效?我给了一个样本代码片段。有两个按钮。一个用于连接，另一个用于浏览文件。如果连接按钮中的连接失败，我想禁用浏览按钮。如何做到这一点?

示例代码片段:

using System;
using System.Drawing;
using System.Net;
using System.Net.Sockets;
using System.Text;
using System.Windows.Forms;
using System.IO;
using System.Collections.Generic;
class Client:Form
{
public Client()
{
    Size = new Size(400, 380);
    Button connect = new Button();
    connect.Parent = this;
    connect.Text = "Connect";
    connect.Location = new Point(295, 20);
    connect.Size = new Size(6 * Font.Height, 2 * Font.Height);
    connect.Click += new EventHandler(ButtonConnectOnClick);
     Button browse = new Button();
    browse.Parent = this;
    browse.Text = "Browse";
    browse.Location = new Point(220, 20);
    browse.Size = new Size(6 * Font.Height, 2 * Font.Height);
    browse.Click += new EventHandler(ButtonbrowseOnClick);
   }
     void ButtonConnectOnClick(object obj, EventArgs ea)  
  {
    tcpClient = new TcpClient("127.0.0.1", 1234);
  }
 [STAThread]
public static void Main()
{
 Application.Run(new Client());
}
}

另一个问题:

是否有办法重置按钮(说，浏览按钮)活动在某个时间，等待再次点击?

bool connectButtonBroken = false;
private void ButtonbrowseOnClick(object sender, EventArgs e)
{
    if(!connectButtonBroken)
    {
        //do code
    }
}

    catch (Exception)
    {
       ButtonConnect.Enabled = false;
    }

    ButtonConnect.Enabled = true;
