WMI 로 쿼리 할수 있는 객체 정보를 볼수 있는 쿼리는 다음과 같음.

 //WMI ~~
            using (System.Management.ManagementObjectSearcher s = new System.Management.ManagementObjectSearcher())
            {
                s.Query = new System.Management.ObjectQuery(
@"SELECT * FROM Meta_Class WHERE __Class LIKE ""%Win32%"" ");
                //s.Query = new System.Management.ObjectQuery(@"SELECT * FROM Win32_Process WHERE NAME = ""NateOnMain.exe"" ");
                //s.Query = new System.Management.ObjectQuery("Select * from Win32_Processor");
                //Win32_Processor
                var k = s.Get();
                foreach (var M in k)
                {
                    foreach (var Q in M.Qualifiers)
                    {
                        string text = string.Format(
                              "Q}} Name:{0}, Value:{1}",
                              Q.Name,
                              Q.Value
                          );
                        this.textBox1.AppendText(text + Environment.NewLine);
                    }

                    foreach (var P in M.Properties)
                    {
                        string text = string.Format(
                            "P}} Name:{0}, Value:{1}",
                            P.Name,
                            P.Value
                        );

                        this.textBox1.AppendText(text + Environment.NewLine);
                    }

                    this.textBox1.AppendText(
                        Environment.NewLine
                        );
                }
            }


위처럼 하면 쿼리 할수 있는 객체들로 나타나고.. 이를 바탕으로 정보를 쿼리 할 수 있음.

여기서 
 디스크 정보를 알고 싶을때 : Win32_LogicalDisk  관련 객체를 위 쿼리결과에서 찾아보고

파라미터명으로 GetPropertyValue를 통해서 값을 취할수 있다. 

  s.Query = new System.Management.ObjectQuery("Select * from Win32_LogicalDisk");
                var k = s.Get();
                foreach (var M in k)
                {
                    this.textBox1.AppendText("> " + M.GetPropertyValue("Caption") + Environment.NewLine);
                    this.textBox1.AppendText(
                        Environment.NewLine
                        );
                }
