1.下載zedGraph控制項：http://download.csdn.net/detail/allisnew/3222512.添加引用 zedGraph.dll3.在工具箱的最後面添加常規控制項--瀏覽--選擇zedgraph.dll4.編寫如下初始化代碼(也可以直接拖一個控制項)：private ZedGraphControl zedGraphControl1 = new ZedGraphControl(); this.zedGraphControl1.Location = new

傳統型程式的開發中，經常考慮能在狀態列實現托盤快捷操作，托盤程式的實現在API時代，還是相對複雜的，首先在MSDN中可以查看其函數細節，然後在根據其要求的參數進行複雜的設定。 在.NET時代，MS封裝了這些麻煩的細節，開發人員可以很容易的實現托盤程式的控制和操作。現以簡單的執行個體為例來說明： 1.添加notifyIcon控制項和contextMenuStrip控制項

單擊工作列 顯示-隱藏切換，右鍵菜單，捕捉關閉表單事件 public partial class frmMain : Form { public frmMain() { InitializeComponent(); } #region 登出 public void Logout() { if

c# 中CountDownEvent的使用class Program { static CountdownEvent _count = new CountdownEvent(3); static void Main(string[] args) { Task.Factory.StartNew(() => { Thread.Sleep(2000);

在一些情境中，需要把多個圖片，合（拼）成為一張 ，合成效果樣本：縱向：橫向：代碼實現： enum ImageMergeOrientation { Horizontal, Vertical }private void CombineImages(FileInfo[] files, string toPath, ImageMergeOrientation mergeType = ImageMergeOrientation.Vertical) {

1.安裝 mongoDb Driver package 2. 使用Wrapper 類： public class MongoDbWrapper : IDisposable { private MongoServer _server; private MongoDatabase _db; public MongoDbWrapper() { var uri =

C#中擷取TimeZoneInfopublic TimeZoneInfo TimeZoneInfo { get { var timeZoneInfoString = _user.TimeZoneInfoString; if (!string.IsNullOrEmpty(timeZoneInfoString)) {

1. 判斷兩個起止時間是否相交：public static bool IsTimeBetween(TimeSpan input, TimeSpan start, TimeSpan end, bool fromInclusice, bool toInclusive) { //http://www.php.cn/ // see if start comes before end if (end < start)

C# 顯示過去了多長時間的函數public string HowLongBeforeNow { get { var ts = new TimeSpan(DateTime.UtcNow.Ticks - CreatedDate.Ticks); var delta = ts.TotalSeconds; const int second = 1;

通常每個Activity對應1個Layout，在onCreate時指定layout（否則引用的還是main的layout）,然後調用startActivity：protected override void OnCreate (Bundle bundle){SetContentView (Resource.Layout.UserRegister);base.OnCreate (bundle);// Create your application herevar btnBack =

public static class AlertExtension{public static void ShowAlert(this Activity activity ,string msg,string title = "", string btnText = "OK"){AlertDialog.Builder builder = new

C# 使用 Xamarin開發應用--list+search[Activity(Label = "ServiceBooking")] public class ServiceBooking : Activity { private SearchView _searchView; private ListView _lv; private ArrayAdapter<string> _adapter;
