Here is the simple example to access the file on remote machine and copy it to local machine.
if (!File.Exists(localFilePath))
{
if (!File.Exists("\\\\\\NeartoME\\sharefolder"))
throw new Exception(localFilePath + "and" + \\NeartoME\sharefolder + "files not found.");
else
File.Copy("\\\\\\NeartoME\\sharefolder, localFilePath);
}
You have to make sure that you have the read permission on the complete path you have specified otherwise though file exists it will throw exception that file not found.
