我无法删除临时文件夹目录。这是我的代码：

private void button8_Click(object sender, EventArgs e)
{
    if(checkBox5.Checked == true)
    {
        try
        {
            string fileDirectory = @"C:\Users\Admin\AppData\Local\Temp";
            if(Directory.Exists(fileDirectory))
            {
                Directory.Delete(fileDirectory);
            }
        }
        catch(IOException ex)
        {
            MessageBox.Show(ex.Message);
        }
    }
    else
    {
        MessageBox.Show("System has been cleaned!");
    } 
}

您可以使用Path.GetTempPath()获取当前用户的临时文件夹。你不应该删除Temp目录本身。最好删除它的文件，跳过你无法删除的所有文件：

System.IO.DirectoryInfo tempDir = new DirectoryInfo(Path.GetTempPath());

foreach (FileInfo file in tempDir.GetFiles())
{
    try
    {
        file.Delete(); 
    }
    catch(IOException ex)
    {
        .....
    }
}
