c#解析字体错误
c#解析字体错误
提问于 2013-02-01 12:43:51
我有一个两个窗口的基本系统，不是使用System.Windows.Forms，而是System.Windows.Controls，其中一个创建了FontDialog，所以我必须包括System.Windows.Forms，因为否则我就不能有字体对话框。在另一个窗口中，我有一个RichTextBox，它应该使用在另一个窗口的FontDialog中选择的字体/大小/样式。
这是用于创建FontDialog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并尝试使用它的字体。
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；“行崩溃：
Value is: Microsoft Sans Serif; 8,25pt

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;两个输出是相等的。
