引言: 小弟使用TRegistry想将注册表中的一些值读出,但是出错了 我是这样做的: 在头文件中添加

#include 

在单元文件中的代码如下

void __fastcall TForm1::Button1Click(TObject *Sender)
{
    TRegistry *RegInfo = new TRegistry();
    try
    {
         RegInfo->RootKey = HKEY_LOCAL_MACHINE;
         RegInfo->OpenKeyReadOnly("\\HARDWARE\\DESCRIPTION\\System");             Label1->Caption  = RegInfo->ReadString("SystemBiosVersion");
         Label2->Caption  = RegInfo->ReadString("SystemBiosDate");
         Label3->Caption  = RegInfo->ReadString("VideoBiosVersion");
         Label4->Caption  = RegInfo->ReadString("VideoBiosDate");
        }
        __finally
        {
            RegInfo->CloseKey();
            delete RegInfo;
        }
}

在单击Button1后就会出现错误: Project Project1.exe raised exception class ERegistryException with message 'Invalid data type for 'SystemBiosVersion'.Process stopped.Use Step or Run to continue. 它的意思是说在读取SystemBiosVersion的时候有错误,我打开注册表,发现SystemBiosVersion的类型不是一般的REG_SZ,而是REG_MULTI_SZ,我就不知道该用什么函数来读取了,想请大大们告诉我应该这样来做呢?谢谢 人生在勤，不索何获？

    int iLen;
    char Buf[4096];
    TRegistry *RegInfo = new TRegistry();
    try
    {
        RegInfo->RootKey = HKEY_LOCAL_MACHINE;
        RegInfo->OpenKeyReadOnly("\\HARDWARE\\DESCRIPTION\\System");
        memset(Buf,0,4096);
        iLen=RegInfo->ReadBinaryData("SystemBiosVersion",Buf,4095);
        for(int i=0;iCaption  = String(Buf);
        Label2->Caption  = RegInfo->ReadString("SystemBiosDate");
        memset(Buf,0,4096);
        iLen=RegInfo->ReadBinaryData("VideoBiosVersion",Buf,4095);
        for(int i=0;iCaption  = String(Buf);
        Label4->Caption  = RegInfo->ReadString("VideoBiosDate");
    }
    __finally
    {
        RegInfo->CloseKey();
        delete RegInfo;
    }
