Question

C#开发 new form3时报错 “.Form3”不包含采用“0”参数的构造函数。

form2代码：
private void 缓冲区分析ToolStripMenuItem_Click(object sender, EventArgs e)
{
Form t = new Form3();
t.ShowDialog();
}
fom3部分代码：
public partial class Form3 : Form
{
public Form3(IHookHelper hookHelper)
{
InitializeComponent();
m_hookHelper=hookHelper;
MapControl=m_hookHelper as IMapControl4;
}

Answer 1

//Form3需要一个IHookHelper类型作为参数。
IHookHelper hookHelper=这里得到对象实例
Form t = new Form3(hookHelper);
