清空控件的值

發現一個很有意思的方法

 

public void ClearCntrValue(Control parContainer)
{
for (int index = 0; index < parContainer.Controls.Count; index++)
{
// 如果是容器類控件，遞歸調用自己
if (parContainer.Controls[index].HasChildren)
{
ClearCntrValue(parContainer.Controls[index]);
}
else
{
switch(parContainer.Controls[index].GetType().Name)
{
case "TextBox":
parContainer.Controls[index].Text = "";
break;
case "RadioButton":
((RadioButton)(parContainer.Controls[index])).Checked = false;
break;
case "CheckBox":
((CheckBox)(parContainer.Controls[index])).Checked = false;
break;
case "ComboBox":
((ComboBox)(parContainer.Controls[index])).Text = "";
break;
}
}
}
}
