vb.net - 字体安装了吗？功能

Question

我可以改进我的功能，不按每个元素进行搜索吗？

#Region " Font Is Installed? Function "

    ' [ Font Is Installed? Function ]
    '
    ' Examples :
    ' MsgBox(Font_Is_Installed("Lucida Console"))

    Private Function Font_Is_Installed(ByVal FontName As String) As Boolean
        Dim AllFonts As New Drawing.Text.InstalledFontCollection
        For Each Font As FontFamily In AllFonts.Families
            If Font.Name.ToLower = FontName.ToLower Then Return True
        Next
        Return False
    End Function

#End Region

UPDATE:

好吧，现在我看到了“.tolist”函数，现在我的代码是这样的:

Private Function Font_Is_Installed(ByVal FontName As String) As Boolean
    Dim AllFonts As New Drawing.Text.InstalledFontCollection
    Dim FontFamily As New FontFamily(FontName)
    If AllFonts.Families.ToList().Contains(FontFamily) Then Return True Else Return False
End Function

我也有同样的问题:是最好用第二种方式改进，还是我可以改进得更好？

Answer 1

这里是

    Public Shared Function IsFontInstalled(ByVal FontName As String) As Boolean
        Using TestFont As Font = New Font(FontName, 10)
            Return CBool(String.Compare(FontName, TestFont.Name, StringComparison.InvariantCultureIgnoreCase) = 0)
        End Using
    End Function
