我正在寻找一个Windows api功能或其他方式来获取位于我LAN上的计算机中的文件夹的内容(文件夹和文件)。当然,我有一个有效的Windows用户和密码,我想访问的每台机器。

您可以使用WMI,查看CIM_DataFile
和CIM_Directory
类。
1.首先,您必须在客户端计算机中启用wmi远程访问。阅读这些文章,看看这个以及Windows版本Connecting to WMI on a Remote Computer
,Securing a Remote WMI Connection
之间的差异。
2.始终必须使用过滤器(Where条件)来限制这些WMI类的结果。
3.总是必须使用Drive
字段作为条件,因为这些类会返回所有驱动器的文件。
4.Wmi将\
(反斜杠)字符解释为保留符号,因此您必须转义该字符以避免WQL语句出现问题。

没有授权部分,它很简单。执行授权的正确方法是调用Windows.pas方法WNetAddConnection2
并按此方式执行。
但是,因为我处于一个简单的黑客模式,我试过这个,它基本上有效:
uses Types, IOUtils, ShellApi; // Works in Delphi XE.
procedure TForm5.Button1Click(Sender: TObject);
var
dirs:TStringDynArray;
files:TStringDynArray;
apath, dir,filename:String;
begin
ListBox1.Items.Clear;
apath := '\\hostname\sharename';
// This should be calling WNetAddConnection2:
// instead It's an evil (portable) hack.
ShellExecute(HWND(0), 'open', PChar('net use /delete '+ apath),
nil,nil,SW_SHOW );
ShellExecute(HWND(0), 'open', PChar('net use '+ apath+' /user:uid pswd'),
nil,nil,SW_SHOW );
dirs := TDirectory.GetDirectories(apath);
if Length(dirs)=0 then
ListBox1.Items.Add('None found.')
else
for dir in dirs do
ListBox1.Items.Add('Directory: '+dir);
files := TDirectory.GetFiles(apath);
for filename in files do
ListBox1.Items.Add('File: '+filename );
end;
为ShellExecute“net use”的丑陋黑客道歉。 (Grin)请注意,我已选择“挂载”此共享文件夹而不给它一个驱动器号,从而避免了如果已映射该驱动器该怎么办的问题。
这是一个带有WNetAddConnection2代码示例的good link,我将链接到该代码而不是偷猎。它显示了一个非邪恶方式的样本。 :-)然后你可以使用我上面显示的目录枚举代码。

我认为这包含在Warren的回答中,但是为了切入追逐, IOUtils.TDirectory 支持UNC:
implementation
uses IOUtils,types;
procedure GetFiles;
var
i: integer;
files: TStringDynArray;
begin
files := TDirectory.GetFiles('\\aServer\aPath\aShare\', '*.aFileFilter');
for i := Low(files)to High(files) do
memo1.Lines.Add(files[i]);
end;
等等...
