推荐答案

根据您的评论，正在创建文件，但是在 bin \Debug 项目下的文件夹。您希望在特定路径中创建文件。



问题是您只在<中指定了相对路径code> FileStream 构造函数：

Based on your comments, the file is being created, but in the bin\Debug folder under your project. You want the file to be created in a specific path.

The problem is that you've only specified a relative path in the FileStream constructor:

new FileStream("test.pdf",FileMode.Create)

此路径将相对于当前路径进行解析，该路径通常与运行应用程序的路径相同。换句话说，项目下的 bin \Debug 路径。



要保存到特定路径，你需要将完整路径传递给 FileStream 构造函数：

This path will be resolved relative to the current path, which is usually the same as the path from which the application is running. In other words, the bin\Debug path under your project.

To save to a specific path, you'll need to pass the full path to the FileStream constructor:

new FileStream(@"C:\Your\Path\Here\test.pdf",FileMode.Create)

注意：小心试图保存记录到 C：驱动器的根目录;大多数应用程序无权写入该目录。确保选择了应用程序具有写权限的路径。

NB: Be careful trying to save the document to the root of your C: drive; most applications won't have permission to write to that directory. Make sure you chose a path to which your application has write permissions.

Quote：

FileStream fs = new FileStream("Chapter1_Example1.pdf", FileMode.Create, FileAccess.Write, FileShare.None);

但是您只在创建模式下初始化。我希望它能解决这个问题。否则，请告诉我。

But you have initialized only in Create mode. I hope it solves the issue. Otherwise, let me know.
