使用系统拥有权限的目录

C:\\ProgramData\\

C:\\Documents and Settings\\All Users\\Application Data\\


   var baseDir = "C:\\ProgramData\\screenshot\\";
                        //var baseDir = "C:\\Documents and Settings\\All Users\\Application Data\\screenshot\\";
                        // 创建截图保存目录
                        Directory.CreateDirectory(baseDir);
