推荐答案

我已经解决了这个问题，以防有人在寻找解决方案：



使用打开/保存对话框下载文件 [ ^ ]

I have solved this problem in case somebody looking for solution:

Download of file with open/save dialog box[^]

//尝试此代码，它会弹出保存按钮，弹出后也会选择//位置它将关闭弹出窗口。



按下下载按钮后插入此代码。弹出窗口打开后会触发。



线程th =新线程（（）=>

{

System.Threading.Thread.Sleep（10000）;

SendKeys.SendWait（{Tab}）;

SendKeys.SendWait（{Tab}） ;

SendKeys.SendWait（{Tab}）;

SendKeys.SendWait（{Enter}）;

System.Threading .Tread.Sleep（5000）;

SendKeys.SendWait（{Tab}）;

SendKeys.SendWait（{Tab}）;

SendKeys.SendWait（{Tab}）;

SendKeys.SendWait（{Enter}）;

}）;

th.SetApartmentState（ApartmentState.MTA）;

th.Start（）;

//try this code, it will press save button from popup and after it will also select //location and it will close popup.

insert this code after download button pressed. it will fire once your popup opened.

Thread th = new Thread(() =>
{
System.Threading.Thread.Sleep(10000);
SendKeys.SendWait("{Tab}");
SendKeys.SendWait("{Tab}");
SendKeys.SendWait("{Tab}");
SendKeys.SendWait("{Enter}");
System.Threading.Thread.Sleep(5000);
SendKeys.SendWait("{Tab}");
SendKeys.SendWait("{Tab}");
SendKeys.SendWait("{Tab}");
SendKeys.SendWait("{Enter}");
});
th.SetApartmentState(ApartmentState.MTA);
th.Start();
