检查字体是否存在的方法

        这里贴一段VB的代码，C#参照也是类似的，读取C盘字体库中的字体，判断字体是否存在，不存在即可使用特殊方法对字体进行安装

这对部分B/S搭建的软件还是能起到作用的，毕竟有些软件设置的字体在系统库中并不存在，如果不安得话，会出现各种乱码的情况，所以

才需要这么做

Private Sub CheckPmingLiuFont() Implements IHealthCheck.CheckPmingLiuFont
        Try
            Dim lo_Fkey As RegistryKey = Registry.LocalMachine
            Dim lo_Rkey As RegistryKey = lo_Fkey.OpenSubKey("SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts")
            Dim ls_FontName() As String = lo_Rkey.GetValueNames()
            Print("20. Check the PMingLiu font.")
            For Each c In ls_FontName
                Dim myvalue As String = lo_Rkey.GetValue(c).ToString
                If myvalue = "mingliu.ttc" Then
                    Print("PMingLiu is existing.")
                    Exit Sub
                End If
            Next
        Catch ex As Exception
        End Try
    End Sub
