我有一個兩個窗口基本系統不使用System.Windows.Forms但System.Windows.Controls,其中一個創建一個FontDialog,所以我不得不包含System.Windows.Forms,因爲否則我將無法使用字體對話框。在另一個窗口中,我有一個RichTextBox,它應該使用在另一個窗口的FontDialog中選擇的字體/大小/樣式。c#解析字體錯誤
這對於創建FontDialog類的窗口類:
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();
}
}
在這裏,我所說的WINDOW1和嘗試使用其字體。
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;
}
}
它輸出正是在FontDialog類選擇的,但隨後在崩潰行 「this.textBox2.FontFamily =克;」:
Value is: Microsoft Sans Serif; 8,25pt

除了你的Window1有點醜陋以外,還要拆分你的排隊並進行調試。你究竟在哪裏得到這個異常:它在'cvt.ConvertFromString()','FontFamily ='中,在...?另外,是字體大小的逗號扔你嗎? –
@lc。它在this.textBox2.FontFamily = g崩潰;如果我評論它然後它不會崩潰 –
好吧,那麼你從'cvt.ConvertFromString(s)'中得到什麼?注意你使用'as' *而不檢查你是否得到一個空結果......不知道你爲什麼不投。 –
