Question

我对PictureBox有疑问。

当我将PictureBox对接到右上方时，它会隐藏位于表单中心的标签的一部分。我怎样才能在PictureBox上贴上标签？我认为问题在于（Image和Label声明）中的停靠声明，这就是它被PictureBox隐藏的原因。

我该如何正确地做到这一点？

表格声明：

$Form = New-Object System.Windows.Forms.Form
$Form.Text = "Something"
$Form.StartPosition = "CenterScreen"
$Form.Topmost = $True
$Form.BackColor = "White"
$Form.Width = [System.Windows.Forms.SystemInformation]::PrimaryMonitorSize.Width 
$Form.Height = [System.Windows.Forms.SystemInformation]::PrimaryMonitorSize.Height - 50
#$Form.AutoSize = $True
$Form.AutoSizeMode = "GrowAndShrink"
$Form.ControlBox = $false
$Form.MinimumSize = New-Object System.Drawing.Size(1280,1024)
$Form.MaximumSize = New-Object System.Drawing.Size(1920,1080)

图片声明：

$Image = [system.drawing.image]::FromFile("C:\xxx.png")
$pictureBox = new-object Windows.Forms.PictureBox 
$pictureBox.Dock = [System.Windows.Forms.DockStyle]::Right
$pictureBox.BackColor = "Transparent"
#$pictureBox.Anchor = [System.Windows.Forms.AnchorStyles]::Right
$pictureBox.AutoSize = $True
$pictureBox.Image=$Image
$Form.Controls.Add($pictureBox)

标签声明：

$redLabel1 = New-Object System.Windows.Forms.Label
$redLabel1.Location = New-Object System.Drawing.Size($Form.Width, $Form.Height)
$redLabel1.AutoSize = $False
$redLabel1.TextAlign = "MiddleCenter"
$redLabel1.Dock = "Fill"
$redLabel1.Text = "Something"
$redLabel1.ForeColor = "Red"
$redLabel1.BackColor = "Transparent"
$Font = New-Object System.Drawing.Font("Arial", 55, [System.Drawing.FontStyle]::Bold)
$redLabel1.Font = $Font
$Form.Controls.Add($redLabel1)

修改

BringToFront()方法已经过测试并且工作率为50％。文本不在表单中居中，当标签符合PictureBox时，文本被包装..我希望该标签以某种方式跳过PictureBox ..

有一种名为Control.BringToFront的方法：https://msdn.microsoft.com/fr-fr/library/system.windows.forms.control.bringtofront(v=vs.110).aspx

所以它应该在你的代码中：

$redLabel1.BringToFront()

我很安静你的标签没有被图片隐藏，但是放在一边这取决于图像的Z顺序 - 以及标签控件（在示例中没有显示丢失控件））：

如果您fill dock是第一个控件，而right dock是第二个控件控制，第一个控件将填充可用的空间剩。
如果您right dock是第一个控件而是fill dock秒控制。第二个控件将占用第一个控件后面的所有空间控制

我已经快速修改了我的Windows-Form wrapper示例，以显示：

$Form    = Form-Control Form @{Text = "Dock test"; StartPosition = "CenterScreen"; Padding = 4}
$Table   = $Form  | Form TableLayoutPanel @{RowCount = 2; ColumnCount = 3; ColumnStyles = ("Percent", 50), "AutoSize", "AutoSize"; Dock = "Fill"}
$Panel   = $Table | Form Panel @{Dock = "Fill"; BorderStyle = "FixedSingle"; BackColor = "Teal"} -Set @{RowSpan = 2}
$Dock = ForEach ($i in 1..2) {
    $Button = $Panel | Form Button @{Location = "25, $(75 * $i - 50)";  Size = "50, 50"; BackColor = "Silver"; Enabled = $False; Text = $i}
    $Group  = $Table | Form GroupBox @{Text = "Dock $i"; AutoSize = $True}
    $Flow   = $Group | Form FlowLayoutPanel @{AutoSize = $True; FlowDirection = "TopDown"; Dock = "Fill"; Padding = 4}
    $Radio  = "None", "Top", "Left", "Bottom", "Right", "Fill" | ForEach {
        $Flow | Form RadioButton @{Text = $_; AutoSize = $True; Click = ([ScriptBlock]::Create("`$Dock[$($i - 1)].Button.Dock = `$This.Text"))}
    }
    New-Object PSObject -Property @{Button = $Button; Group = $Group; Flow = $Flow; Radio = $Radio}
}
$Close  = $Table | Form Button @{Text = "Close"; Dock = "Bottom"; Click = {$Form.Close()}} -Set @{ColumnSpan = 2}
$Form.ShowDialog()

仅举几例：

可能的解决方案：

不要将标签对接，而是将其定位或使用锚点（另请参阅： What is the difference between Dock and Anchor
使用其他对接组合，例如：图片right和标签Bottom？

使用Windows窗体在Powershell中由PictureBox隐藏的标签
