测试方法：
publicvoidTestNetWorkConnection()
{
stringlocalpath="X:";
//intstatus=NetworkConnection.Connect(@"//192.168.0.2/test",localpath,@"test","test");
intstatus=NetworkConnection.Connect("////192.168.0.2//test",localpath,@"test","test");
if(status==(int)ERROR_ID.ERROR_SUCCESS)
{
FileStreamfs=newFileStream(localpath+@"//123.txt",FileMode.OpenOrCreate);
using(StreamWriterstream=newStreamWriter(fs))
{
stream.WriteLine("你好呀，成功了");
stream.Flush();
stream.Close();
}
fs.Close();
}
else
{
Console.WriteLine(status);
}
NetworkConnection.Disconnect(localpath);
}
