C# VS 2013一个.CS文件上的慢速文本编辑器

我在这里问这个问题是希望得到开发者的回应…因为我在网上搜索过，什么都找不到

我目前在Visual Studio 2013中使用windows服务。该项目运行良好，我能够使用没有任何问题的VS。当我打开一个特定文件时，文本编辑器变得非常慢，intelli sense和auto complete都非常慢，只有一个.cs文件。切换回任何其他.cs文件，然后文本编辑器按预期工作

为什么只有这一个文件的文本编辑器会变慢？我该如何修复它？只有大约1000行代码，.cs文件中最复杂的是并行foreach循环

可能解析文档需要很长时间

编辑：

似乎Parallel.ForEach会导致编辑器运行缓慢。如果我用普通的ForEach替换Parallel.ForEach，那么就没有问题了

为什么会发生这种情况？我如何修复它
