Question

我试图使用StreamWriter指定存储创建文件的位置：

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

我收到此错误消息：

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

最有可能的原因在错误消息中说明：“找不到路径的一部分” - 流编写器不会创建文件夹，只会创建文件。

使用Directory.CreateDirectory及相关功能确保文件夹存在。

附注：请使用特殊的Path.Combine方法来构造路径而不是手动字符串连接。

使用StreamWriter存储在特定路径中
