            {
                REG_NONE= 0,
                REG_SZ = 1,
                REG_EXPAND_SZ = 2,
                REG_BINARY = 3,
                REG_DWORD = 4,
                REG_DWORD_LITTLE_ENDIAN = 4,
                REG_DWORD_BIG_ENDIAN = 5,
                REG_LINK = 6,
                REG_MULTI_SZ = 7,
                REG_RESOURCE_LIST = 8,
                REG_FULL_RESOURCE_DESCRIPTOR = 9,
                REG_RESOURCE_REQUIREMENTS_LIST = 10,
                REG_QWORD_LITTLE_ENDIAN = 11
            }

            [DllImport("advapi32.dll", CharSet = CharSet.Auto, BestFitMapping = false)]
            private static extern int RegSetKeyValueW  (
            HKEY hkey, 
            string lpSubKey,
            string lpValueName,
            VALUE_TYPE type, 
            byte[] data, 
            uint dataLength);
            public int set_key(HKEY hkey, string subkey, string valuename){
                return RegSetKeyValueW(hkey, subkey, valuename, VALUE_TYPE.REG_NONE, null, 0);
            }
       }
}

在我的例子中，数据等于null，类型是REG_NONE。您可以根据需要更改set_key对象：

$Advapiobject = New-Object 'AdvapiSolution.Advapi'
$Advapiobject.set_key('HKEY_CURRENT_USER',$yoursubkey, $yourvaluename, 'REG_NONE')

另一种方法是使用静态方法set_key。 将set_key更改为public static int set_key：

[AdvapiSolution.Advapi]::set_key('HKEY_CURRENT_USER',$yoursubkey, $yourvaluename, 'REG_NONE')。

如果返回0，则没有问题。如果函数失败，则返回值为Winerror.h中定义的非零错误码。
