所以，我有以下三行 c# 代码：

string pageAnnotationTextFilePath = currentPagePath.Substring(0, currentPagePath.Length-4) + ".txt";
print (pageAnnotationTextFilePath);
StreamWriter sw = new StreamWriter(pageAnnotationTextFilePath, false);

当我运行它时，我首先收到以下打印消息，表示名为 pageAnnotationTextFilePath 的字符串的值：

file://C:/Users/USER/Desktop/Accessible/Assets/IO/Books/A community of learners/king/pages/page1.txt

这是正确的，也应该如此。但是，程序中的下一行给了我下面的错误。似乎正在发生的事情是我的路径正在被 StreamWriter 初始化类改变——导致项目的位置被附加到我提供的路径的第一部分。为什么要这样做，为什么要这样做？我在堆栈跟踪中提到的路径就在顶部，这里：

DirectoryNotFoundException: Could not find a part of the path "C:\Users\USER\Desktop\Accessible\file:\C:\Users\USER\Desktop\Accessible\Assets\IO\Books\A community of learners\king\pages\page1.txt".
System.IO.FileStream..ctor (System.String path, FileMode mode, FileAccess access, FileShare share, Int32 bufferSize, Boolean anonymous, FileOptions options)

这是一个提示

'找不到路径的一部分“C:\Users\USER\Desktop\Accessible\file:\C:\Users\USER\Desktop\Accessible\Assets\IO\Books\A community of learners\king\pages\ page1.txt"'

并注意您的打印输出是

'file://C:/Users/USER/Desktop/Accessible/Assets/IO/Books/A community of learners/king/pages/page1.txt'

因此，您正在将此字符串提供给 StreamWriter。StreamWriter 正在获取此字符串并将其用作相对路径。您的工作目录必须是：

'C:\Users\USER\Desktop\Accessible\'

两者正在相互附加。长话短说，你必须去掉“file://”
