1.循环遍历

|
private void GetControls(Control fatherControl){ Control.ControlCollection sonControls = fatherControl.Controls; foreach (Control control in sonControls) { listBox1.Items.Add(control.Name); }} |
结果：能获取到Panel、GroupBox、TabControl等控件
问题：Panel等控件上面的子控件获取不到
2.递归遍历

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); } }} |
结果：能获取到绝大多数控件
问题：Timer、ContextMenuStrip等控件获取不到
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); }} |
结果：所有控件都被获取到了
DevExpress控件无法使用this.Controls进行遍历，只能通过反射的方法获得，如下代码：

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); } } }} |
