c#中小弟我在子窗口怎么访问MDI父窗口的状态栏

Answer 1

FormMain 中:
public void SetLabTipText(string tip)
{
this.tslabTip.Text = tip;
}
public void Button_Click(object (object sender, EventArgs e)
{
FormSub _FormSub =new FormSub(this);
_FormSub.Show();
}
FormSub 中:
private FormMain fm;
public FormSub(FormMain _fm)
{
this.fm=_fm
}
然后就可以通过 fm.SetLabTipText("你要设置的文本");
