C# 分析字体错误

本文关键字：错误 字体 | 更新日期: 2023-09-27 17:56:51

我有两个窗口基本系统，不使用System.Windows.Forms，而是使用System.Windows.Controls，其中一个创建一个FontDialog，所以我必须包含System.Windows.Forms，否则我将无法拥有字体对话框。在另一个窗口中，我有一个富文本框，它应该使用在另一个窗口的字体对话框中选择的字体/大小/样式。

这是创建字体对话框的窗口的类：

public partial class Window1 : Window
{
    public FontDialog font;
    public Window1(String name)
    {
        InitializeComponent();
        this.textBox1.Text = name;
    }
    private void button2_Click(object sender, RoutedEventArgs e)
    {
        font = new FontDialog();
        font.ShowDialog();
    }
}

在这里，我调用 Window1 并尝试使用其字体。

private void button2_Click(object sender, RoutedEventArgs e)
{
    Window1 a = new Window1(this.name);
    a.ShowDialog();
    var cvt = new FontConverter();
    string s = cvt.ConvertToString(a.font.Font);
    Console.Out.WriteLine("Value is: " + s);
    System.Windows.Media.FontFamily g = (System.Windows.Media.FontFamily) cvt.ConvertFromString(s);
    if (g != null)
    {
         this.textBox2.FontFamily = g;
    }
}

它准确地输出在 FontDialog 中选择的内容，但随后在"this.textBox2.FontFamily = g;"行处崩溃：

Value is: Microsoft Sans Serif; 8,25pt
'_.NetworkingGT_Incrementer.vshost.exe' (Managed (v4.0.30319)): Loaded 'C:'Windows'Microsoft.Net'assembly'GAC_MSIL'WindowsBase.resources'v4.0_4.0.0.0_pt-BR_31bf3856ad364e35'WindowsBase.resources.dll'

C# 分析字体错误

已解决：

var cvt = new FontConverter();
string s = cvt.ConvertToString(a.font.Font);
Console.Out.WriteLine("Value is: " + s);
System.Windows.Media.FontFamily g = new System.Windows.Media.FontFamily(s);
Console.Out.WriteLine("Value is: " + g.ToString());
this.textBox2.FontFamily = g;

两个输出相等。
