为什么我的BackgroundWork不起作用?

[langya001]

        private void button2_Click(object sender, EventArgs e)
        {
            //安装APK
            this.backgroundWorker1.RunWorkerAsync();
        }

        private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
        {
            //安装APK
            //this.backgroundWorker1.RunWorkerAsync();
            System.Diagnostics.Process InstallApk = new System.Diagnostics.Process();
            InstallApk.StartInfo.FileName = Application.StartupPath + @"\tools\adb.exe";
            InstallApk.StartInfo.UseShellExecute = false;
            InstallApk.StartInfo.RedirectStandardInput = true;
            InstallApk.StartInfo.RedirectStandardOutput = true;
            InstallApk.StartInfo.RedirectStandardError = false;
            InstallApk.StartInfo.CreateNoWindow = true;
            System.IO.DirectoryInfo ApkFolder = new System.IO.DirectoryInfo(Application.StartupPath + @"\apk");
            foreach (System.IO.FileInfo ApkFile in ApkFolder.GetFiles("*.apk", System.IO.SearchOption.AllDirectories))
            {
                InstallApk.StartInfo.Arguments = "install -r " + @"apk\" + ApkFile.Name;
                InstallApk.Start();
                InstallApk.WaitForExit();
                //通过这个函数将处理的百分比传递给进度条控件
                //this.backgroundWorker1.ReportProgress();
                label1.Text += ApkFile.Name + "安装完成!\n";
                label1.Update();
                InstallApk.Close();
            }
            //执行

        }

这样不起作用.我如果把DoWork里的代码复制到Click里的话又有效...救命呀~~~~~~~~~~~~~

不可能吧...你调试下呗,看是 不能运行 ONWOEK 还是怎么的..应该是不能运行的问题吧...
查看下 事件绑定..

调试了..完全不起作用..我还傻等了半天..看不到执行...

完全不起 作用 是 什么意思?不能执行 backgroundWorker1_DoWork么?
那么是你没有绑定方法啊应该是..去隐藏代码中看看绑定好了没有 .就是desinger后缀名字的文件

你不会是网上直接复制的吧

[langya001]

确定是自己手工打的..光是函数名你也看得出呀.都是专用的函数..怎么可能复制..

        private void button2_Click(object sender, EventArgs e)
        {
            //安装APK
            //this.backgroundWorker1.RunWorkerAsync();
            System.Diagnostics.Process InstallApk = new System.Diagnostics.Process();
            InstallApk.StartInfo.FileName = Application.StartupPath + @"\tools\adb.exe";
            InstallApk.StartInfo.UseShellExecute = false;
            InstallApk.StartInfo.RedirectStandardInput = true;
            InstallApk.StartInfo.RedirectStandardOutput = true;
            InstallApk.StartInfo.RedirectStandardError = false;
            InstallApk.StartInfo.CreateNoWindow = true;
            System.IO.DirectoryInfo ApkFolder = new System.IO.DirectoryInfo(Application.StartupPath + @"\apk");
            foreach (System.IO.FileInfo ApkFile in ApkFolder.GetFiles("*.apk", System.IO.SearchOption.AllDirectories))
            {
                InstallApk.StartInfo.Arguments = "install -r " + @"apk\" + ApkFile.Name;
                InstallApk.Start();
                InstallApk.WaitForExit();
                //通过这个函数将处理的百分比传递给进度条控件
                //this.backgroundWorker1.ReportProgress();
                label1.Text += ApkFile.Name + "安装完成!\n";
                label1.Update();
                InstallApk.Close();
            }
        }

        private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
        {
            //安装APK
            //this.backgroundWorker1.RunWorkerAsync();

            //执行

        }

代码放到前面.这样就能运行..虽然会卡..
