开发过程中用到的一些知识
在后台给前台控件赋值16进制的颜色
控件名.Background = new SolidColorBrush((Color)ColorConverter.ConvertFromString("#FF54C0DC"));
wpf监控方法
Timer timer; timer = new System.Threading.Timer(new TimerCallback(MyDelegate)); //实例化一个Timer时间器并启动 timer.Change(0, 1000); delegate void UpdateTimer(); void MyDelegate(object state) { this.Dispatcher.BeginInvoke(new UpdateTimer(MyEventFunc)); } //需要实现的方法 void MyEventFunc() { }
另外一种
DispatcherTimer t = null; 下面的可以写在load事件里面 t = new DispatcherTimer(); t.Interval = new TimeSpan(0, 0, 1); t.Tick += OnTimer; t.IsEnabled = true; t.Start(); 在别的地方实现OnTimer方法
C# 轻松获取路径中文件名、目录、扩展名等
string path = "C:\\dir1\\dir2\\foo.txt";
string str = "GetFullPath:" + Path.GetFullPath(path) + "\r\n";
str += "GetDirectoryName:" + Path.GetDirectoryName(path) + "\r\n";
str += "GetFileName:" + Path.GetFileName(path) + "\r\n";
str += "GetFileNameWithoutExtension:" + Path.GetFileNameWithoutExtension(path) + "\r\n";
str += "GetExtension:" + Path.GetExtension(path) + "\r\n";
str += "GetPathRoot:" + Path.GetPathRoot(path) + "\r\n";
MessageBox.Show(str);
结果:
GetFullPath:C:\dir1\dir2\foo.txt
GetDirectoryName:C:\dir1\dir2
GetFileName:foo.txt
GetFileNameWithoutExtension:foo
GetExtension:.txt
GetPathRoot:C:\
