Question

我使用这段代码来获取远程计算机上进程的好处。代码在99.9％的情况下运行良好，但有时它会一直挂在scope.Connect()上，即使我指定超时为10秒。

有人知道如何防止这种WMI挂断吗？

代码：

// Configure the connection settings.
ConnectionOptions options = new ConnectionOptions();
options.Timeout = new TimeSpan(0, 0, 10);
ManagementPath path = new ManagementPath(String.Format("\\\\{0}\\root\\cimv2", machine));
ManagementScope scope = new ManagementScope(path, options);

// Try and connect to the remote (or local) machine.
try {
    scope.Connect();
} catch (ManagementException ex) {
    // Failed to authenticate properly.
    return "Failed to authenticate: " + ex.Message;
} catch (System.Runtime.InteropServices.COMException) {
    // Unable to connect to the RPC service on the remote machine.
    return "Unable to connect to RPC service";
} catch (System.UnauthorizedAccessException) {
    // User not authorized.
    return "Error: Unauthorized access";
}

有趣的是，我发现这个代码挂在哪台远程PC上。我尝试使用PowerShell连接到它，PowerShell也挂起了！我用这个代码：

Get-WmiObject -Namespace "root\cimv2" -Class Win32_Process -ComputerName pcname

应用程序挂起在WMI Connect上
