我尝试了下面的代码

WindowsIdentity ImpersonatedIdentity = new WindowsIdentity(tokenHandle);
WindowsImpersonationContext MyImpersonation = ImpersonatedIdentity.Impersonate();

它抛出以下错误

我想您的主机和目标计算机都是基于Windows的。我以前做过,但我的代码看起来有点不同。将尝试制作一些场景(简而言之)。
首先导入这个dll。检查参数并播放输入格式。我真的不记得它们应该是什么样子
[System.Runtime.InteropServices.DllImport("advapi32.dll", SetLastError = true, CharSet = System.Runtime.InteropServices.CharSet.Unicode)]
public static extern bool LogonUser(String lpszUsername, String lpszDomain, String lpszPassword, int dwLogonType, int dwLogonProvider, ref IntPtr phToken);
public class TestClass
{
public void TestMethod()
{
IntPtr admin_token = default(IntPtr);
WindowsIdentity wid_current = WindowsIdentity.GetCurrent();
WindowsIdentity wid_admin = null;
WindowsImpersonationContext wic = null;
try
{
if (LogonUser(User, userDomain, Password, DwLogonType, DwLogonProvider, ref admin_token))
{
wid_admin = new WindowsIdentity(admin_token);
wic = wid_admin.Impersonate();
if (!Directory.Exists(@"C:\TempFiles")) Directory.CreateDirectory(@"C:\TempFiles");
file.SaveAs(@"C:\TempFiles\" + fileName
//+ GUID
+ "");
}
}
catch (Exception ex)
{
...
}
}
在这里,我将一些文件保存在另一个域中,但您可以检查代码以了解如何对其进行授权。谢谢您的帮助。
iStream=newfilestream(filepath,FileMode.Open,FileAccess.Read,FileShare.Read)代码>与之不同。顺便说一句:这个空洞的口号太可怕了。甚至不适用于示例代码。当然,模拟和访问unc位置是不同的事情,但可以根据作者的需要提供一些想法。啊哈,同意使用异常处理,但这已经足够了,例如,它并没有要求任何实际使用:)@Liamneesan是的,我看到了你的更新。1.您的帐户(用户名/密码)应该可以访问目标主机。对此要有把握;2.尝试使用用户名格式,我不记得它应该是什么。可能是域名域名\\UserName@IuriiMaksimov我给出了我的域\\用户名和密码
。但仍然不可能复制@UweKeim,我正在尝试one@UweKeim那么NetworkCredential
有什么用呢?我可以知道为什么我会投反对票吗?
