使用StreamWriter存储在特定路径中

本文关键字：路径 StreamWriter 存储 使用 | 更新日期: 2023-09-27 18:23:57

我正在尝试使用StreamWriter:指定创建文件的存储位置

string getCurrentPath = Environment.CurrentDirectory;
StreamWriter writeFile = new StreamWriter(@"" +getCurrentPath + "''NDependProject''OceanAPIDependencies.xml");
writeFile.Close();

我收到这个错误消息：

    Unhandled Exception: System.IO.DirectoryNotFoundException: Could not find a part
 of the path 'D:'Project_Summer'ExtensionDirectoryTraversal'ExtensionDirectoryTr
aversal'bin'Debug'NDependProject'OceanAPIDependencies.xml'.

使用StreamWriter存储在特定路径中

最可能的原因在错误消息中说明："找不到路径的一部分"-流写入程序不会创建文件夹，只会创建文件。

使用Directory.CreateDirectory和相关函数来确保文件夹存在。

附带说明：请使用特殊的Path.Combine方法来构造路径，而不是手动串接。
