c# - .Net GetProcesses 的访问被拒绝

Question

我无法连接到远程计算机以获取正在运行的进程列表。对于我的测试机器，我使用用户名@"ownme\veritas"。密码只是“veritas”。示例域是“ownme”。

return new System.Management.ConnectionOptions()
{
    //certainly these variables have been checked and are correct
    Username = UserCredential.DomainUser,
    Password = UserCredential.Password
};

这是我尝试进行连接的地方。我不知道，但这实际上可能是这里的问题。也可能是我没有在上面的 ConnectionOptions 中填写足够的字段。我引用了这两篇文章:

https://msdn.microsoft.com/en-us/library/system.management.connectionoptions.authentication.aspx

我不知道我做错了什么

ManagementScope scope = new ManagementScope($"\\\\{computer.DnsHostname}\\root\\cimv2", connectionOptions);
scope.Connect();

//Error: Access is denied
var processes = System.Diagnostics.Process.GetProcesses(dnsHostName);

Answer 1

GetProcesses 将使用当前用户凭据连接到远程计算机，而不是您通过 ConnectionOptions 指定的凭据。

您需要使用以正确的凭据创建的 WMI 范围对象来发出对进程的查询，如下所示:

//..

SelectQuery query = new SelectQuery("select * from Win32_Process"); //query processes

using (ManagementObjectSearcher searcher = new ManagementObjectSearcher(scope, query))
{
    using (ManagementObjectCollection collection = searcher.Get())
    {
        foreach (var process in collection) //loop through results
        {
            var name = process["name"]; //process name
            //Do something with process
        }
    }
}
