客户端调用代码

procedure TMainForm.b_ChaXunClick(Sender: TObject);
var i,len:integer;
zpByte:TByteDynArray;
tmpstream:TMemorystream;
begin
DeleteFile('c:\xp.jpg');
zpImg.Picture:=nil;

tmpstream:=TMemorystream.Create;
try
zpByte:=(HTTPRIO1 as WebServiceSoap).GetPhoto(Str1,Str1,Str1);//Str1,Str1,Str1已赋值，类型是String
except
tmpstream.Free;
exit;
end;

len:= length(zpByte);
for i:=0 to len-1 do
tmpstream.Write(zpByte[i],sizeof(zpByte[i]));
tmpstream.SaveToFile('c:\xp.jpg');

if FileExists('c:\xp.jpg') then
zpImg.Picture.LoadFromFile('c:\xp.jpg');
tmpstream.Free;
end;




报错位置

try
zpByte:=(HTTPRIO1 as WebServiceSoap).GetPhoto(Str1,Str1,Str1);
