C#FlowDocument RichTextBox对齐不会持续
我继承了一些C#代码,它定义了一个C#FlowDocument RichTextBox对齐不会持续,c#,xaml,alignment,richtextbox,C#,Xaml,Alignment,Richtextbox,我继承了一些C#代码,它定义了一个RichTextBox,带有用于文本左对齐、居中对齐和右对齐的按钮。运行程序时,使用“居中”按钮使文本居中,但当我保存文件并重新加载时,居中消失 将保留字体大小、样式和颜色等格式。当我查看Xaml文件输出时,我看到的是“TextAlignment=Justify”,而不是“TextAlignment=Center”。我使用的是Visual C#2010,如果有人能够验证这是一个已在更高版本中修复的问题,我将很乐意升级 代码如下: private void
