推荐答案

dlg.ShowDialog没有这样的属性。

if（result == System.Windows.Forms.DialogResult。好的）

更改这样的条件



将线路更改为bool？ result = dlg.ShowDialog（）to bool result = dlg.ShowDialog（）

dlg.ShowDialog no such property exists.
if (result ==System.Windows.Forms.DialogResult.OK)
change condition like this

change the line to bool? result = dlg.ShowDialog() to bool result = dlg.ShowDialog()

是的它会：ShowDialog是一种方法。

改变这个：

Yes it will: ShowDialog is a method.
Change this:

if (dlg.ShowDialog ==System.Windows.Forms.DialogResult.OK)

对此：

To this:

if (dlg.ShowDialog() == System.Windows.Forms.DialogResult.OK)
