Question

C# ArcGis Engine二次开发 一个窗口调用另一个窗口的控件

比如 Mapcontrol1控件是窗口1中的 并且有

public void button1_Click(object sender, EventArgs e)
{

OpenFileDialog openFileDialog1 = new OpenFileDialog();
openFileDialog1.Filter = "lyr文件(*.lyr)|*.lyr";
openFileDialog1.InitialDirectory = @"D:\\图层文件";
openFileDialog1.Multiselect = false;
DialogResult pDialogResult = openFileDialog1.ShowDialog();
if (pDialogResult != DialogResult.OK)
return;
string pFileName = openFileDialog1.FileName;
axMapControl1.AddLayerFromFile(pFileName);
axMapControl1.ActiveView.Refresh(）;
}
按按钮实现了往地图中加载了一个图层。
现在我想在另外一个窗口form中实现一个功能，就是按一个form2中按钮就实现form1中按钮的功能
我是这样的
private void sddata_SelectionChangeCommitted(object sender, EventArgs e)
{
Form1 frm1 = new Form1();

string a = sddata.SelectedItem.ToString();//方法2 选中日期传入字符串a
MessageBox.Show(a);

OpenFileDialog openFileDialog1 = new OpenFileDialog();
openFileDialog1.Filter = "lyr文件(*.lyr)|*.lyr";
openFileDialog1.InitialDirectory = @"D:\\图层文件";
openFileDialog1.Multiselect = false;
DialogResult pDialogResult = openFileDialog1.ShowDialog();
if (pDialogResult != DialogResult.OK)
return;
string pFileName = openFileDialog1.FileName;
frm1.axMapControl1.AddLayerFromFile(pFileName);
frm1.axMapControl1.ActiveView.Refresh();

}
但是不能实现，我是新手，请大神赐教啊 分都了

Answer 1

Form1 frm1 = new Form1();

frm1.button1_Click(null,null);

追问

还是不能实现，点form2中的按钮毫无反应，但是点form1中按钮可以成功实现。
