C# 如何以编程方式更改有效的windows图标?
我需要创建10万个不同的测试图标,可以在C#或powershell中。 实际上,我有10k个同名的图标文件,我想我可以很容易地读入二进制图标,转换成字节,注入一些随机数,然后写回一个文件,但它不像我看到的那样工作C# 如何以编程方式更改有效的windows图标?,c#,powershell,binary,icons,C#,Powershell,Binary,Icons,我需要创建10万个不同的测试图标,可以在C#或powershell中。 实际上,我有10k个同名的图标文件,我想我可以很容易地读入二进制图标,转换成字节,注入一些随机数,然后写回一个文件,但它不像我看到的那样工作 $fi = @(Get-ChildItem D:\icons -rec | ForEach-Object -Process {$_.FullName}) # | select -first $amount) $no = 0 foreach($i in $fi) { $
$fi = @(Get-ChildItem D:\icons -rec | ForEach-Object -Process {$_.FullName}) # | select -first $amount)
$no = 0
foreach($i in $fi)
{
$array = Read-FileByte $i;
$array = $array + [System.Text.Encoding]::UTF8.GetBytes($no)
[System.IO.File]::WriteAllBytes($i, $array)
$no++
}
在此代码运行之后,windows仍然认为图标相同
另一种方法是通过编程方式创建有效的10k图标,
有办法做到这一点吗?
谢谢您可以使用此代码生成任意数量的随机图标:
