我已经使用 GUI .net 框架构建了一个 powershell 脚本，该框架为用户提供了一个图形界面，以将备用数据流 (ADS) 添加到 NTFS 文件系统上的文件。

下面是我为 powershell 脚本编写的代码：

<# 
This script is a GUI featured way to add extended attributes to files 
#>

Add-Type -AssemblyName System.Windows.Forms
[System.Windows.Forms.Application]::EnableVisualStyles()

#region begin GUI{ 

$Form                            = New-Object system.Windows.Forms.Form
$Form.ClientSize                 = '600,600'
$Form.text                       = "Add Extended Attributes"
$Form.TopMost                    = $false

# Add Extended Attributes Label
$mainLabel                       = New-Object system.Windows.Forms.Label
$mainLabel.text                  = "Add Extended Attributes"
$mainLabel.AutoSize              = $true
$mainLabel.width                 = 25
$mainLabel.height                = 10
$mainLabel.location              = New-Object System.Drawing.Point(180,10)
$mainLabel.Font                  = 'Microsoft …

我遇到一个问题，我使用扩展运算符设置状态，但函数调用useEffect仅将从 API 拉出的最后一个值设置为状态。

// get all events to display on load
const getEvents = () => {
    console.log(props.id);
    axios.get(API.EVENTS.ROOT + props.id).then(
        res => {
            const data = res.data;
            setEvent(data);
            console.log(data);
            // event start and end dates
            setStart(new Date(data.start));
            setEnd(new Date(data.finish));
            // breakout dates
            for (let i = 0; i < data.breakouts.length; i++) {
                console.log(data.breakouts[i].start);
                data.breakouts[i].start = new Date(data.breakouts[i].start);
                data.breakouts[i].end = new Date(data.breakouts[i].end);
                console.log(data.breakouts[i].name, "test" + data.breakouts[i].start);
                // set date picker initial value 
                setFields({
                    ...fields,
                    [data.breakouts[i].name]: data.breakouts[i].start
                })
                console.log(fields); …
