点击下载按钮后，会提示点击保存按钮.已尝试使用以下

想要发送键 (Alt+n + TAB + ENTER)，尝试通过更改一些内容但最终得到相同的结果.

want to send keys (Alt+n + TAB + ENTER), tried by changing few things but end up with the same result.

推荐答案

使用 System.Windows.Forms.SendKeys 类模拟发送键.

To emulate send keys you want to use System.Windows.Forms.SendKeys class.

加号 (+)、脱字符 (^)、百分号 (%)、波浪号 (~) 和括号 () 对 SendKeys 有特殊意义.指定其中之一这些字符，将其括在大括号 ({}) 中

The plus sign (+), caret (^), percent sign (%), tilde (~), and parentheses () have special meanings to SendKeys. To specify one of these characters, enclose it within braces ({})

在您的情况下，根据文档，代码示例应如下所示:

In your case, according to documentation, code sample should look like:

Add-Type -AssemblyName System.Windows.Forms
[System.Windows.Forms.SendKeys]::SendWait("%n{TAB}{ENTER}")

地点:

• % 代表 ALT 按钮；
• n 代表 n 按钮；
• {TAB} 代表 TAB 按钮；
• {ENTER} 代表 ENTER 按钮.

• % stands for ALT button;
• n stands for n button;
• {TAB} stands for TAB button;
• {ENTER} stands for ENTER button.
