可以修改,代码如下:
form1:
private void button10_Click(object sender, System.EventArgs e)
{
Form2 mFrm=new Form2();
mFrm.Frm=this;
mFrm.Show();
}
form2:
private Form1 _Frm;
public Form1 Frm
{
set
{
_Frm=value;
}
}
form1:
private void button10_Click(object sender, System.EventArgs e)
{
Form2 mFrm=new Form2();
mFrm.Frm=this;
mFrm.Show();
}
form2:
private Form1 _Frm;
public Form1 Frm
{
set
{
_Frm=value;
}
}

比如:Form1 pForm1=new Form1();
pForm1.Text="a";
这样就可以了。至于在另一个窗口中操作form1的text属性,也要先实例化一个form1的对象,然后操作,这样是可以的。
比如在form2中,先声明form1的对象:
private form1 pForm1;然后在按钮事件下添加代码:
if(pForm1!=null)
{
pForm1.Close();
pForm1=null;
}
pForm1=new form1();
pForm1.Text="a";
pForm1.Show();this.Hide(); //隐藏form2
