您可以检查该键的值（如Access.Application.12）代替。 HKEY_LOCAL_MACHINE \ SOFTWARE \ Classes下\ Access.Application \ CURVER

You can check this key for a value (eg. Access.Application.12) instead. HKEY_LOCAL_MACHINE\SOFTWARE\Classes\Access.Application\CurVer

所以，你的code线将是：

So your line of code would be:

RegistryKey rootKey = Registry.ClassesRoot.OpenSubKey(@"Access.Application\CurVer", false);

if (rootKey == null) return false;

string value = rootKey.GetValue("").ToString();
int verNum = int.Parse(value.subString(value.indexOf("Access.Application.")));
if (value.StartsWith("Access.Application.") && verNum >= 12)
{ return true; }
