Answer 1

you probably dont have enough permissions....

try adding credentials :

    Process p = new Process();
    process.StartInfo.UserName = "aaaa";  
    process.StartInfo.Password = "xxxxx";
...
...

also , verify that :

read permissions for : d:\\123.png

write permissions for : C:\\windows\\system32

Answer 2

Access Denied may be caused by several reasons, such as user permissions or file being in use. Since the command line seems to be OK, I suggest to check whether your application was run by a Windows user that has permission to write to C:\\windows\\system32.

Answer 3

you need to run CMD.exe as admin try following

        Process p = new Process();
        p.StartInfo.FileName = "cmd.exe";
        p.StartInfo.Verb = "runas";
        p.StartInfo.UseShellExecute = false;
        p.StartInfo.RedirectStandardInput = true;
        p.Start();

        p.StandardInput.WriteLine(@"/c xcopy d:\123.png C:\windows\system32");
