[英]C# - WMI InvalidOperationException when trying to run a script on a remote machine
[英]Searching for a File on Remote Machine WMI C#
我想在遠程機器上搜索文件。 我不知道EXACT文件路徑,但我知道它在C:\\ Windows \\ System下
我的查詢在WMI中是這樣的
string querystr = "SELECT * FROM CIM_DataFile Where Path='C:\\Windows\\System'";
ObjectQuery query = new ObjectQuery(querystr );
ManagementObjectSearcher Searcher = new ManagementObjectSearcher(Scope, query);
我得到無效的查詢錯誤。
查詢有效嗎? 有什么方法可以指定Path Under嗎?
您的代碼中有兩個問題
\\
char,因為這是WMI中的保留符號 試試這個樣本
using System;
using System.Collections.Generic;
using System.Management;
using System.Text;
namespace GetWMI_Info
{
class Program
{
static void Main(string[] args)
{
try
{
string ComputerName = "localhost";
ManagementScope Scope;
if (!ComputerName.Equals("localhost", StringComparison.OrdinalIgnoreCase))
{
ConnectionOptions Conn = new ConnectionOptions();
Conn.Username = "";
Conn.Password = "";
Conn.Authority = "ntlmdomain:DOMAIN";
Scope = new ManagementScope(String.Format("\\\\{0}\\root\\CIMV2", ComputerName), Conn);
}
else
Scope = new ManagementScope(String.Format("\\\\{0}\\root\\CIMV2", ComputerName), null);
Scope.Connect();
string Drive = "c:";
//look how the \ char is escaped.
string Path = "\\\\Windows\\\\System32\\\\";
ObjectQuery Query = new ObjectQuery(string.Format("SELECT * FROM CIM_DataFile Where Drive='{0}' AND Path='{1}' ", Drive, Path));
ManagementObjectSearcher Searcher = new ManagementObjectSearcher(Scope, Query);
foreach (ManagementObject WmiObject in Searcher.Get())
{
Console.WriteLine("{0}",(string)WmiObject["Name"]);// String
}
}
catch (Exception e)
{
Console.WriteLine(String.Format("Exception {0} Trace {1}",e.Message,e.StackTrace));
}
Console.WriteLine("Press Enter to exit");
Console.Read();
}
}
}
