Question

我正在尝试在文本框中读取插入的字符，但是我发现它很难，因为如果我的最后一个字符是空格（字符串必须“按原样”读取，这是一个要求），文本框Text属性返回类似“\ r \ n”的东西（是的，有8个空格）。

有关如何避免这种情况的任何建议？我需要阅读最后一个空格，而不是删除它，但我不想要那么奇怪的事情。

感谢您的回答。

            bool restart = false;
            lock (a.SyncRoot)
            {
                var w = new ConfigureWindow(Properties.Settings.Default.SecondsPerWord, Properties.Settings.Default.ShowWhenMessageIncoming, Properties.Settings.Default.UseMessageSeparator, Properties.Settings.Default.MessageSeparator);
                var result = w.ShowDialog();
                if (result.HasValue && result.Value == true)
                {
                    Properties.Settings.Default.SecondsPerWord = w.SecondsPerWord;
                    Properties.Settings.Default.ShowWhenMessageIncoming = w.ShowWhenMessageIncoming;
                    Properties.Settings.Default.MessageSeparator = w.MessageSeparator;
                    Properties.Settings.Default.UseMessageSeparator = w.UseMessageSeparator;
                    Properties.Settings.Default.Save();
                    restart = true;
                }
            }
            if (restart)
                App.Restart();
        }), this);
    }

注意：我在这一刻用xml：space测试过，通常不存在。

Answer 1

对不起，好像我自己发现了这个问题并且非常愚蠢。

事实上，我出于某种原因在“设置”字符串中存储了“\ r \ n”。在我的配置窗口重新加载后，我似乎无法从文本框中的文本中删除该字符串，因为我的文本框是单行，而\ r \ n是在第二行。

我仍然不确定为什么我不能删除所有这些空格，但我认为这就是答案。如果有人有更好的，我会很高兴他/她。

感谢。

编辑1： 似乎在app.config和.settings文件之间出现了问题，我通过手动编辑它们来修复它。

编辑2： 我发现了问题：如果我在保存后立即重新启动应用程序，我不知道为什么我的字符串会被这些字符填充。我不明白为什么会这样。

当空格是最后一个字符时，Textbox返回一个奇怪的字符串
