我正在尝试按照this教程保存一些简单的用户数据。我正在为Android构建。
在第一次编译中，一切正常。但是-我今天回到我的项目，并且遇到以下错误：（从那时起我做了一些工作，但是我不认为是什么引起了问题。）
DirectoryNotFoundException: Could not find a part of the path

之所以使用“ Log71”，是因为为每个创建的新文件分配了一个数字，该数字在每次创建新文件时都会递增。
我尝试了以下解决方案：
这是保存文件的代码：
string sessionNumber = PlayerPrefs.GetInt("sessionNumberKey").ToString();
string customFileName = "/Log:" + sessionNumber + ".test";
// Save the data
BinaryFormatter formatter = new BinaryFormatter();
string path = Application.persistentDataPath + customFileName;
FileStream stream = new FileStream(path, FileMode.Create);
SaveSession saveSessionData = new SaveSession(inputcontroller);
formatter.Serialize(stream, saveSessionData);
stream.Close();
Debug.Log("The file has been saved with the filename: " + path);
预期结果是消息“文件已用文件名（{filename）保存”，并在持久数据路径中（在我的计算机C:\Users\Ben\AppData\LocalLow\Top Notch Development\Simple Swim上创建一个新文件）
但是，目前，我收到错误消息，没有新文件。
答案 0 :(得分：1)
在Windows中，文件名不能包含冒号。
您应该删除冒号。 （：）
