楼上正解
按照楼上的,你要的结果是再把S输出就行了
那如何得到它的二进制码呢?

}
换成2进制代码??
不会
帮顶
关注中
怎么输出呀大哥,换成二进制码...
这样好象可以,没测试,你去试试吧;
var
S: TMemoryStream;
x: string;
begin
S := TMemoryStream.Create;
S.LoadFromFile('目录\文件名');
SetLength(x, s.Size);
move(s.memory^, x[1], s.size);
s.free;
显示X;
end;
流里面本身就是二进制码,你说的应该是如何显示二进制码
to zhang3652 非常感谢,我试过了,不行哦。
procedure TForm1.Button1Click(Sender: TObject);
var
GetString,filenamepath:string;
astream:TMemoryStream;
buffer:array of char;
begin
if OpenDialog1.Execute then
begin
filenamepath:=OpenDialog1.FileName;
astream:=TMemoryStream.Create;
astream.LoadFromFile(filenamepath);
setlength(buffer,astream.size);
move(astream.memory^,buffer[0],astream.Size);
GetString:=string(buffer);
Edit1.Text:= GetString;
end;
得不到二进码
procedure TForm1.Button1Click(Sender: TObject);
var
S: TStream;
B: TStream;
I: Integer;
C: Byte;
D: string;
begin
B := TMemoryStream.Create;
Image1.Picture.Bitmap.SaveToStream(B);
B.Position := 0;
S := TFileStream.Create('d:\111.txt', fmCreate);
for I := 0 to B.Size - 1 do
begin
B.Read(C, 1);
D := IntToHex(C, 2);
S.Write(D[1], 2);
if (I <> 0) and ((I mod 32) = 0) then
begin
D := #13 + #10;
S.Write(D[1], 2);
end;
end;
B.Free;
S.Free;
end;
按搂住的要求应该把
Image1.Picture.Bitmap.SaveToStream(B);
改为
TMemoryStream(B).LoadFromFile('目录\文件名');
呵呵,谢谢楼上两位,我试试。
呵呵,搞定了。。
procedure TForm1.Button2Click(Sender: TObject);
var
S: TStream;
B: TStream;
I: Integer;
C: Byte;
D: string;
begin
B := TMemoryStream.Create;
// Image1.Picture.Bitmap.SaveToStream(B);
TMemoryStream(B).LoadFromFile('E:\Delphi程序\Picture\jz12.jpg');
B.Position := 0;
S := TFileStream.Create('d:\111.txt', fmCreate);
for I := 1 to B.Size do
begin
B.Read(C, 1);
D := IntToHex(C, 2);
S.Write(D[1], 2);
if ((I mod 32) = 0) then
begin
D := #13 + #10;
S.Write(D[1], 2);
end;
end;
B.Free;
S.Free;
end;
呵呵,搞定了。。
=============================================================
你提问表达方式有问题,这不是二进制流输出,应该叫二进制流的文本格式输出,你早说清楚,答案早出来了.
