C# WinForm遍歷窗體控件的3種方法

1.循環遍歷

private void GetControls(Control fatherControl) { Control.ControlCollection sonControls = fatherControl.Controls; foreach (Control control in sonControls) { listBox1.Items.Add(control.Name); } } 

結果：能獲取到Panel、GroupBox、TabControl等控件
問題：Panel等控件上面的子控件獲取不到

2.遞歸遍歷

private void GetControls(Control fatherControl) { Control.ControlCollection sonControls = fatherControl.Controls; foreach (Control control in sonControls) { listBox1.Items.Add(control.Name); if (control.Controls != null) { GetControls(control); } } } 

結果：能獲取到絕大多數控件
問題：Timer、ContextMenuStrip等控件獲取不到

3.使用反射

private void GetControls(Control fatherControl) { System.Reflection.FieldInfo[] fieldInfo = this.GetType().GetFields(BindingFlags.NonPublic | BindingFlags.Instance); for (int i = 0; i < fieldInfo.Length; i++) { listBox1.Items.Add(fieldInfo[i].Name); } } 

結果：所有控件都被獲取到了

DevExpress控件無法使用this.Controls進行遍歷，只能通過反射的方法獲得，如下代碼：

public void SearchBarManager() { Type FormType = this.GetType(); FieldInfo[] fi = FormType.GetFields(BindingFlags.NonPublic | BindingFlags.Instance | BindingFlags.Public); foreach (FieldInfo info in fi) { if (info.FieldType == typeof(DevExpress.XtraBars.BarManager)) { DevExpress.XtraBars.BarManager bar = (info.GetValue(this)) as DevExpress.XtraBars.BarManager; foreach (DevExpress.XtraBars.BarItem bi in bar.Items) { MessageBox.Show(bi.Name); } } } }
