推荐答案

尝试这样，

Hi,

try like this,

TextBox txt = (TextBox)childForm1.ParentForm.Controls["txtbox1"];
// txtbox1 ID or name of textbox
// childForm1 is the object of the child form
if(txt !=null)
{
   MessageBox.Show(txt.Text.Trim());
}

希望它有所帮助。

hope it helps.

也许这是好方法：

以子格式创建属性作为父级;

maybe this is good way :
make a property in child form as parent;

private ParentForm parent;
public ParentForm Parent
{
get{return parent;}
set{parent=value}
}

你有父表格对象作为你的孩子表格的成员这个属性。

然后使用这个父母形式的代码：

well you have parent form object as a member of your child form whith this property.
then use this code in parent form:

ChildForm child=new ChildForm();
child.Parent=this;
child.Show();

这样，您可以访问子表单中的父表单成员！ />
希望有帮助！

with this , you have access to parent form members in your child form!
hope help !
