winform窗体之间用委托传递参数

子窗体上:
public delegate void ChildFormSendMessage(string a,bool b);
public ChildFormSendMessage btnSaveClick;

private btnSave_Click(object sender,EventArgs e)
{
if(btnSaveClick!=null)
{
btnSaveClick(this.txtBoxName.Text,This.chkBoxIsNew.Checked);
}
}

父窗体上
ChildForm c=new ChildForm();
c.btnSaveClick+=new ChildFormSendMessage(process);
c.show();
private void process(string a, bool b)
{
....
}
