C# winform在子窗体操作父窗体报错

Question

用事件//父窗体代码
GrantStuICCard stuForm = new GrantStuICCard(stuInfo);
stuForm.RefeshStuData+=RefeshStuData;
                    stuForm.Owner = this;//子窗体代码
public delegate void RefeshStuDataHandler();
public event RefeshStuDataHandler RefeshStuData;
//子窗体调用
if(RefeshStuData!=null)
{
RefeshStuData();
}

Answer 1

或者public void RefeshStuData()
{
studentBindingPage.Invoke(new MethodInvoker( delegate() {  pageIndex = Convert.ToInt32(studentBindingPage.PositionItem.Text); }));
                // studentBindingPage.PositionItem.Text = pageIndex.ToString();
 stuTchName.Invoke(new MethodInvoker( delegate() { stuTchName = txtStuTchName.Text; }));
this.cmbICCardStatus.Invoke(new MethodInvoker( delegate() {  ICCardStatus = this.cmbICCardStatus.SelectedIndex + 1;}));
}
