这两句过不了

关闭窗体时报错： private void LogInfo_FormClosing(object sender, FormClosingEventArgs e) { DialogResult meDR = MessageBox.Show("是否结束备份！", "提示信息", MessageBoxButtons.YesNoCancel, MessageBoxIcon.Information); if (meDR == DialogResult.Yes) { HasDispose = true; BackupClass.KillProcess("cmd"); BackupClass.KillProcess("exp"); this.Dispose(); } else if (meDR == DialogResult.Yes) { HasDispose = true; e.Cancel = false; } else if (meDR == DialogResult.Cancel) { e.Cancel = true; }

[qbilbo]

HasDispose是自己定义的变量？为什么不用窗体的IsDisposed属性？

[gishys]

isdispose也试过，还是同样的结果，我是想怎么能让他不进入CmdProcess_ErrorDataReceived、CmdProcess_OutputDataReceived这两个事件

[gishys]

进程还在这个窗体就关不了，因为是oracle 数据库备份，事件很长，我想关闭窗体进程还在运行

引用 4 楼 gishys 的回复:

1、你不要注册这两个事件 2、FormClosing事件加上try catch
