.NET 控制台应用程序按计划抛出错误。 手动执行时运行良好

Question

So I decided to make a console application to automate some repetitive jobs that I generally do on a daily basis. The objective is to move some files to a network location as backup. The application runs fine when executed manually. But when scheduled, it throws an error. On examining the log file (to which all program output is mapped), I found the following stack trace and exception message:

at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)
   at System.IO.File.InternalCopy(String sourceFileName, String destFileName, Boolean overwrite, Boolean checkHost)
   at System.IO.File.Copy(String sourceFileName, String destFileName)
   at automateDump.Program.Main(String[] args) in D:\software\automateDump\Program.cs:line 78
 The user name or password is incorrect.

I'm using the File.Copy(src, dest) method in System.IO .

And for context, the file paths are:

Source: D:\u01\test.file . Destination: \\NetDrive\test.file

Any help would be appreciated.

EDIT 1

Code:

if (File.Exists(movePath + et1))
{
     Console.WriteLine($"Copying {et1} to network location. Size - {sizeInMegaBytes(new FileInfo(movePath + et1).Length)}");
     File.Copy(movePath + et1, networkPath + et1);
     Console.WriteLine("Done Copying");
}

movePath and networkPath are source and destination paths, and et1 is the file.

sizeInMegaBytes() is a utility function that I wrote. It's irrelevant in this context.

EDIT 2

Exception Handling code:

catch (Exception ex)
{
    using (logger = File.AppendText(@"D:\u01\logs.txt"))
    {
         logger.WriteLine($"{ex.StackTrace} \n {ex.Message}");
    }    
}

Theory: you have not checked the option to save the user password for the task:

Note the explanatory text: using a UNC path means you are trying to access a non-local resource!
