void __fastcall TForm1::CheckBanben(int num,int Address,byte array[]) 
{
                 String str="";  
                  str=str+array[Address+1]+"."; 
                  str=str+array[Address+2]+"."; 
                  str=str+array[Address+3]+"."; 、 
                  str=str+array[Address+4]; 
                  Memo1->Lines->Add(str) ; 

          上面这样写我可以读到正确的ip:192.168.0.236 
      问题1: 
              如果是 
                  String str="";  
                  str=array[Address+1]+".";//这句变化 
                  str=str+array[Address+2]+"."; 
                  str=str+array[Address+3]+"."; 、 
                  str=str+array[Address+4]; 
                  Memo1->Lines->Add(str) ; 
                为什么会出现8v@168.0.236这样的乱码? 
      问题2: 
              如果是 
                  str=array[Address+1]+".";//四句都变化 
                  str+=array[Address+2]+"."; 
                  str+=array[Address+3]+"."; 
                  str+=array[Address+4]; 
                  Memo1->Lines->Add(str) ;              
                为什么会出现.236(前面只剩下若干空格) 
}

调用上述的函数 
void __fastcall TForm1::banben(byte ReBuf[],int len)  

    String str=""; 
    for(int i=6;i <len-1;i++) 
    { 
        AnsiString TempStr="0x"+IntToHex(ReBuf[i],2) ; 
      str+= AnsiString((char)(TempStr. ToInt())); 
      if(IntToHex(ReBuf[i],2)=="5C")              
        { 
          CheckBanben(ReBuf[i+1],i+1,ReBuf); 
        } 
    } 

}
