调用 TextPointer.GetCharacterRect(LogicalDirection 方向) 时挂起

[英]Hanging When Calling TextPointer.GetCharacterRect(LogicalDirection direction)

原文 2019-09-18 21:46:41 5 0 c#/ .net/ wpf/ richtextbox

When I call TextPointer.GetCharacterRect(LogicalDirection direction) my WPF application sometimes hangs for 3 to 10 minutes or more.当我调用TextPointer.GetCharacterRect(LogicalDirection direction)时，我的 WPF 应用程序有时会挂起 3 到 10 分钟或更长时间。

The TextPointer is valid. TextPointer 是有效的。 The RichTextBox text is long - just under 3 million characters, but I've ran this code on longer text and not had this issue. RichTextBox 文本很长 - 不到 300 万个字符，但我已经在更长的文本上运行了此代码并且没有遇到此问题。

Some TextPointers return the from the call to GetCharacterRect almost immediately and then others take minutes - I can't find any pattern except it is always the same TextPointers.一些TextPointers 几乎立即从对GetCharacterRect 的调用中返回，然后其他人需要几分钟——我找不到任何模式，除非它总是相同的TextPointers。

Any suggestions?有什么建议么？
