在管理軟件研發過程中，特別是涉及項目管理或者生產計划方面，都需要一款類似微軟project的控件對項目下的分解任務進行圖形展示（甘特圖）。下面介紹一下在WindowsForm下如何實現類似微軟project軟件的甘特圖？最終的效果如下所示：
1、VS2012創建一個Windows應用程序GanttChartControl，並添加甘特圖控件庫，結構如下：
（注：此處甘特圖控件是一款開源庫，源碼可從網上自行下載）
2、自定義任務類和資源類，代碼如下：
1 #region 自定義任務和資源類
2 /// <summary>
3 ///自定義資源 4 /// </summary>
5 [Serializable] 6 public class MyResource 7 { 8 public string Name { get; set; } 9 } 10 /// <summary>
11 /// 自定義任務類,繼承 Task 接口 (可選) 12 /// </summary>
13 [Serializable] 14 public class MyTask : Task 15 { 16 public MyTask(ProjectManager manager) : base() 17 { 18 Manager = manager; 19 } 20
21 private ProjectManager Manager { get; set; } 22
23 public new int Start { get { return base.Start; } set { Manager.SetStart(this, value); } } 24 public new int End { get { return base.End; } set { Manager.SetEnd(this, value); } } 25 public new int Duration { get { return base.Duration; } set { Manager.SetDuration(this, value); } } 26 public new float Complete { get { return base.Complete; } set { Manager.SetComplete(this, value); } } 27 } 28 #endregion
為了能夠保存甘特圖信息，需要將任務類和資源類標志為[Serializable]。自定義任務類需要繼承Task接口。
3、創建項目和任務，代碼如下：
1 // 創建項目和任務
2 _mManager = new ProjectManager(); 3 var p項目= new MyTask(_mManager) { Name = "項目" }; 4 _mManager.Add(p項目); 5 var t售前任務組 = new MyTask(_mManager) { Name = "售前階段" }; 6 var t項目啟動 = new MyTask(_mManager) { Name = "項目啟動會" }; 7 var t需求調研 = new MyTask(_mManager) { Name = "需求調研" }; 8 var t方案撰寫 = new MyTask(_mManager) { Name = "方案撰寫" }; 9 var t方案確認 = new MyTask(_mManager) { Name = "方案確認" }; 10 // 用ProjectManager類Add方法添加任務
11 _mManager.Add(t售前任務組); 12 _mManager.Add(t項目啟動); 13 _mManager.Add(t需求調研); 14 _mManager.Add(t方案撰寫); 15 _mManager.Add(t方案確認);
首先需要用 ProjectManager _mManager = new ProjectManager();創建一個ProjectManager，后續所有的任務都需要添加到此類Add方法添加任務進行管理。
任務的其他屬性用下述代碼進行設置：
1 // 用ProjectManager類SetDuration方法設置任務工期
2 _mManager.SetDuration(t項目啟動, 3); 3 _mManager.SetDuration(t需求調研, 5); 4 _mManager.SetDuration(t方案撰寫, 7); 5 _mManager.SetDuration(t方案確認, 4); 6 _mManager.SetDuration(tUI設計, 3); 7 _mManager.SetDuration(t數據庫設計, 5); 8
9 //用ProjectManager類Split方法對任務進行分段
10 _mManager.Split(t數據庫設計, new MyTask(_mManager), new MyTask(_mManager), 2); 11
12 // 設置任務的完成率
13 t項目啟動.Complete = 0.9f; 14 t需求調研.Complete = 0.5f; 15 t方案撰寫.Complete = 0.4f;
4、任務分組和任務銜接關系定義
有了任務后，可以對任務的上下關系（分組）和接替關系進行定義，代碼如下：
1 // 給任務分組
2 _mManager.Group(p項目, t售前任務組); 3 _mManager.Group(p項目, t開發階段); 4 _mManager.Group(p項目, t實施階段); 5
6
7 _mManager.Group(t售前任務組, t項目啟動); 8 _mManager.Group(t售前任務組, t需求調研); 9 _mManager.Group(t售前任務組, t方案撰寫); 10 _mManager.Group(t售前任務組, t方案確認); 11 //任務銜接關系設置，不支持類型
12 _mManager.Relate(t項目啟動, t需求調研); 13 _mManager.Relate(t需求調研, t方案撰寫); 14 _mManager.Relate(t方案撰寫, t方案確認); 15
16
17 _mManager.Group(t開發階段, tUI設計); 18 _mManager.Group(t開發階段, t數據庫設計); 19 _mManager.Group(t開發階段, t編碼); 20 _mManager.Group(t開發階段, t測試); 21
22 _mManager.Relate(t方案確認, tUI設計); 23
24 _mManager.Relate(tUI設計, t數據庫設計); 25 _mManager.Relate(t數據庫設計, t編碼); 26 _mManager.Relate(t編碼, t測試); 27
28 _mManager.Group(t實施階段, t系統安裝和初始化); 29 _mManager.Group(t實施階段, t系統培訓); 30 _mManager.Group(t實施階段, t系統驗收); 31 _mManager.Group(t實施階段, t結項); 32
33 _mManager.Relate(t測試, t系統安裝和初始化); 34 _mManager.Relate(t系統安裝和初始化, t系統培訓); 35 _mManager.Relate(t系統培訓, t系統驗收); 36 _mManager.Relate(t系統驗收, t結項);
5、資源分配
1 // 創建並設置任務資源（人、材料、設備等），任務資源可自定義
2 var jake = new MyResource() { Name = "Jake" }; 3 var peter = new MyResource() { Name = "Peter" }; 4 var john = new MyResource() { Name = "John" }; 5 var lucas = new MyResource() { Name = "Lucas" }; 6 var james = new MyResource() { Name = "James" }; 7 var mary = new MyResource() { Name = "Mary" }; 8 // 給任務分配資源
9 _mManager.Assign(t項目啟動, jake); 10 _mManager.Assign(t項目啟動, peter); 11 _mManager.Assign(t項目啟動, john); 12 _mManager.Assign(t需求調研, jake); 13 _mManager.Assign(t需求調研, james); 14 _mManager.Assign(t數據庫設計, james); 15 _mManager.Assign(t數據庫設計, lucas); 16 _mManager.Assign(t方案撰寫, mary); 17 _mManager.Assign(t方案撰寫, lucas); 18 _mManager.Assign(t方案撰寫, john);
6、甘特圖初始化
1 //甘特圖初始化並創建任務代理
2 _mChart.Init(_mManager); 3 _mChart.CreateTaskDelegate = delegate() { return new MyTask(_mManager); }; 4
5 // 任務事件監聽
6 _mChart.TaskMouseOver += new EventHandler<TaskMouseEventArgs>(_mChart_TaskMouseOver); 7 _mChart.TaskMouseOut += new EventHandler<TaskMouseEventArgs>(_mChart_TaskMouseOut); 8 _mChart.TaskSelected += new EventHandler<TaskMouseEventArgs>(_mChart_TaskSelected); 9 _mChart.PaintOverlay += _mOverlay.ChartOverlayPainter; 10 //允許任務拖拽
11 _mChart.AllowTaskDragDrop = true; 12
13 // 設置任務提示內容，可自定義
14 _mChart.SetToolTip(t項目啟動, string.Join(", ", _mManager.ResourcesOf(t項目啟動).Select(x => (x as MyResource).Name))); 15 _mChart.SetToolTip(t需求調研, string.Join(", ", _mManager.ResourcesOf(t需求調研).Select(x => (x as MyResource).Name))); 16 _mChart.SetToolTip(t數據庫設計, string.Join(", ", _mManager.ResourcesOf(t數據庫設計).Select(x => (x as MyResource).Name))); 17 _mChart.SetToolTip(t方案撰寫, string.Join(", ", _mManager.ResourcesOf(t方案撰寫).Select(x => (x as MyResource).Name))); 18
19 //設置圖形日期信息
20 _mManager.TimeScale = TimeScale.Day; 21 var span = DateTime.Today - _mManager.Start; 22 _mManager.Now = (int)Math.Round(span.TotalDays); 23 // 設置圖形標題顯示日期格式
24 _mChart.TimeScaleDisplay = TimeScaleDisplay.DayOfWeek;
