首先得要将远程目录设置为共享，然后需要设置权限，具体操作为：在文件夹右键-》属性 弹出的面板中，“共享“项中设置共享此文件夹，然后点”权限”按钮设置权限，添加Administrator(连接是用的用户名)，ASPNET，NETWORK SERVICES用户，并将它们附上“完全控制“权限，同样在”安全”项中也添加上述三个用户，设置“完全控制“权限。
以下为具体代码：
private RemoteCopy m_remoteCopy;
public void WriteData()
{
FileStream stream = null;
StreamWriter streamwriter = null;
try
{
String m_RemoteHost = ConfigurationManager.AppSettings["RemoteHost"]; //"10.150.39.188"远程主机
String m_RemoteUser = ConfigurationManager.AppSettings["RemoteUser"]; //"Administrator"用户名
String m_RemotePwd = ConfigurationManager.AppSettings["RemotePwd"]; //"123456"密码
// m_remoteCopy = new RemoteCopy(m_RemoteHost, m_RemoteUser, m_RemotePwd);//初使化远程主机、用户名、密码
// int n = m_remoteCopy.Initialize();//初始化与远程主机的连接，在已经连接过的情况下将不再连接
(以上两句不要也是可行的，为了程序严谨和程序健壮，还是要加上的）
string FileName = @"\\" + "10.150.39.26" + "\\RemoteCopy\\resultaa.txt";
stream = File.Open(FileName, FileMode.Create, FileAccess.ReadWrite, FileShare.ReadWrite);
streamwriter = new StreamWriter(stream);
streamwriter.WriteLine(0.123555 + "," +0.256885 + "," + 4568 + "," + 54555);//随便写一行数据
streamwriter.Flush();
}
catch (Exception e)
{
//此处还需添加异常处理
}
finally
{
streamwriter.Close();
stream.Close();
// m_remoteCopy.UnInitialize();//断开与远程主机的连接(与前面连接初始化两句一样，为了严谨和程序健壮，还是需要加上）
}
//连接与断开远程主机类
