.NET Framework 类库
Form.ActiveMdiChild 属性
获取当前活动的多文档界面 (MDI) 子窗口。

命名空间:System.Windows.Forms
程序集:System.Windows.Forms（在 system.windows.forms.dll 中）

示例:
public void ClearAllChildFormText()
{
// Obtain a reference to the currently active MDI child form.
Form tempChild = this.ActiveMdiChild;

// Loop through all controls on the child form.
for (int i = 0; i < tempChild.Controls.Count; i++)
{
// Determine if the current control on the child form is a TextBox.
if (tempChild.Controls[i] is TextBox)
{
// Clear the contents of the control since it is a TextBox.
tempChild.Controls[i].Text = "";
}
}
}
