使用 GetDataType函数,请参阅Delphi的帮助:
TRegistry.GetDataType
Returns the enumerated data type of a specified data value associated with the current key.
type TRegDataType= (rdUnknown, rdString, rdExpandString, rdInteger, rdBinary);
function GetDataType(const ValueName: String): TRegDataType;
Description
Call GetDataType to determine the data type of a data value associated with the current key. ValueName is a string containing the name of the data value to query.
GetDataType returns an enumerated value of type TRegDataType. TRegDataType can be one of the following values
Value Meaning
rdUnknown Data value type is of no defined value type.
rdString Data value type is a null-terminated string. It is a Unicode or ANSI string depending on whether the application calls the Unicode or ANSI string functions.
rdExpandString Data value type is a null-terminated string that contains unexpanded references to environment variables (for example, "%PATH%"). It is a Unicode or ANSI string depending on whether the application calls the Unicode or ANSI string functions.
rdInteger Data value type is a32-bit number.
rdBinary Data value type is binary data, in any form.
