DELPHI 如何将二进制dump文件转换为txt文本格式

procedure TForm1.btn3Click(Sender: TObject);
var
iFileHandle, iFileLength, iBytesRead : Integer;
byteBuff : array of Byte;

i : Integer;
str, stra, strb : string;
begin
iFileHandle := FileOpen('C://myFile1.txt', fmOpenRead);
iFileLength := FileSeek(iFileHandle, 0, 2);
ShowMessage('iFileLength = ' + IntToStr(iFileLength));

FileSeek(iFileHandle, 0, 0);

SetLength(byteBuff, iFileLength);

iBytesRead := FileRead(iFileHandle, byteBuff[0], iFileLength);

FileClose(iFileHandle);

stra := StrPas( PChar(@byteBuff[1]));
ShowMessage('stra=' + stra);

strb := StrPas(@byteBuff[0]);
ShowMessage('strb=' + strb);

SetLength(str, 5);
Move(byteBuff[0], str[1], 5);
ShowMessage('str=' + str);

str := '';
for i:=0 to iBytesRead do
begin
str := str + chr(byteBuff[i]);
end;

ShowMessage(str);
byteBuff := nil;
end;

myFile1.txt  内容：
[true我是中国人]c

对应的二进制内容为：

弹出结果顺序：

注意:  
byteBuff
