确定，这里就是我在做蒸馏只System.Management电话：

OK, here's what I'm doing distilled to only the System.Management calls:

简单的查询和方法调用通过相同的连接工作。该查询不会。而该文件存在于远程计算机上。线索？

Simple queries and Method invokes work over the same connection. This query won't. And the file exists on the remote machine. Clues?

myQuery = "Select * from CIM_DataFile Where Drive = 'C:' AND Path = '\\Users\\someguy\\Documents\\' AND FileName = 'Default' AND Extension = 'rdp'";

options = new ConnectionOptions();
options.Username = myUsername;
options.Password = myPassword;
options.Authority = "ntlmdomain:MYDOMAIN";
scope = new ManagementScope("\\\\REMOTEMACHINE\\root\\CIMV2", options);
scope.Connect();
searcher = new ManagementObjectSearcher(scope, new ObjectQuery(myQuery));
myResults = searcher.Get();

ManagementObjectSearcher.Get（）让我一个ManagementException说：无效的查询。一个简单的查询，比如，说：SELECT * FROM Win32_NetworkAdapter这工作。

ManagementObjectSearcher.Get() gets me a ManagementException saying "Invalid query." A simpler query, like, say, "SELECT * FROM Win32_NetworkAdapter", works.

我试图减少哪来到只有一个，即SELECT * FROM CIM_DataFile凡拓='RDP'。它的工作原理，但显然没有得到我想要的。 （编辑之前，我误以为它没有工作，即使是这样，见注释）。我在这里穷途末路

I tried to reduce the WHERE's to just one, i.e. "Select * from CIM_DataFile Where Extension = 'rdp'". It works, although obviously it doesn't get me what I want. (Before the edit I mistakenly thought it didn't work even then; see comments) I'm at the end of the rope here.

推荐答案

我是个白痴。请不要打我。

I am an idiot. Please don't beat me up.

首先，查询功能仅对如果你通过文件名的所有组件在WHERE子句。

Firstly, the query only works reliably if you pass ALL components of the file name in WHERE clauses.

其次，我不得不反斜线一倍，在路径组成部分，我是做错了。我所做的：

Secondly, I had to double the backslashes in the path component, and I was doing it wrong. I did:

pathPath.Replace("\\", "\\\\");

而我所要做的就是：

Whereas what I had to do was:

pathPath = pathPath.Replace("\\", "\\\\");

这是正确的。我的工作是与string.replace（）改变了字符串在线的假设下。坏C＃新手。坏的。

That's right. I worked under the assumption that String.Replace() changed the string in-line. Bad C# newbie. Bad.
