C # obtain hardware information Through WMI

Sometimes you need to obtain hardware information and bind the user to log on.

 

The Code is as follows:

  1  private string GetProcessSerialNumber()  2         {  3             try  4             {  5                 ManagementObjectCollection ProcessCollection = new ManagementObjectSearcher(  6                       new System.Management.ManagementScope("\\\\localhost\\root\\cimv2"),  7                       new System.Management.ObjectQuery("SELECT * FROM Win32_processor")  8                       ).Get();  9                 if (ProcessCollection != null && ProcessCollection.Count > 0) 10                 { 11                     StringBuilder sb = new StringBuilder(); 12                     foreach (ManagementObject mo in ProcessCollection) 13                     { 14                         sb.Append(mo["ProcessorId"]); 15                     } 16                     return sb.ToString(); 17                 } 18                 else 19                 { 20                     return ""; 21                 } 22             } 23             catch (Exception) 24             {                 25                 return ""; 26             } 27         } 28  29         private string GetMotherBoardSerialNumber() 30         { 31             try 32             { 33                 ManagementObjectCollection ProcessCollection = new ManagementObjectSearcher( 34                       new System.Management.ManagementScope("\\\\localhost\\root\\cimv2"), 35                       new System.Management.ObjectQuery("SELECT * FROM Win32_bios") 36                       ).Get(); 37                 if (ProcessCollection != null && ProcessCollection.Count > 0) 38                 { 39                     StringBuilder sb = new StringBuilder(); 40                     foreach (ManagementObject mo in ProcessCollection) 41                     { 42                         sb.Append(mo["SerialNumber"]); 43                     } 44                     return sb.ToString(); 45                 } 46                 else 47                 { 48                     return ""; 49                 } 50             } 51             catch (Exception) 52             { 53                 return ""; 54             } 55         } 56  57         private string GetHardDisk0SerialNumber() 58         { 59             try 60             { 61                 ManagementObjectCollection ProcessCollection = new ManagementObjectSearcher( 62                       new System.Management.ManagementScope("\\\\localhost\\root\\cimv2"), 63                       new System.Management.ObjectQuery("SELECT * FROM Win32_DiskDrive") 64                       ).Get(); 65                 if (ProcessCollection != null && ProcessCollection.Count > 0) 66                 { 67                     StringBuilder sb = new StringBuilder(); 68                     foreach (ManagementObject mo in ProcessCollection) 69                     { 70                         if(mo["Name"].ToString().IndexOf("DRIVE0")!=-1) 71                         sb.Append(mo["SerialNumber"]); 72                     } 73                     return sb.ToString(); 74                 } 75                 else 76                 { 77                     return ""; 78                 } 79             } 80             catch (Exception) 81             { 82                 return ""; 83             } 84         } 85  86         private string GetNetWorkMACSerialNumber() 87         { 88             try 89             { 90                 ManagementObjectCollection ProcessCollection = new ManagementObjectSearcher( 91                       new System.Management.ManagementScope("\\\\localhost\\root\\cimv2"), 92                       new System.Management.ObjectQuery("SELECT * FROM Win32_NetworkAdapterConfiguration") 93                       ).Get(); 94                 if (ProcessCollection != null && ProcessCollection.Count > 0) 95                 { 96                     StringBuilder sb = new StringBuilder(); 97                     foreach (ManagementObject mo in ProcessCollection) 98                     { 99                         if (mo["IPEnabled"].ToString() == "True")100                             sb.Append(mo["MacAddress"]);101                     }102                     return sb.ToString();103                 }104                 else105                 {106                     return "";107                 }108             }109             catch (Exception)110             {111                 return "";112             }113         }
