      id = myFile.Read();

      published = myFile.Read();
      stock = myFile.Read();
      price = myFile.Read();
      type = myFile.ReadLine();
      title = myFile.ReadLine();
      author = myFile.ReadLine();

      myFile.Close();
    }

    void write_one_record(int id, int newstock, 
      int published, double price, string type, 
      string title, string author)
    {
      StreamWriter myFile = File.OpenWrite("Inventory.dat");

      myFile.WriteLine(id);
      myFile.WriteLine(newstock);
      myFile.WriteLine(published);
      myFile.WriteLine(price);
      myFile.WriteLine(type);
      myFile.WriteLine(title);
      myFile.WriteLine(author);

      myFile.Close();
    }
  }
}

代码意味着打开一个库存文件，拉入信息，将其传递回main，主要我将要求用户更新库存＃。然后将该数字传递给它写入的writefunction。出于某种原因，当我尝试启动以查看它是否有效时（代码不是100 $完成但仍应编译）。它说的是项目.exe缺少并且无法调试的内容。

Answer 1

您没有获得EXE，因为您的代码

中有错误

StreamWriter myFile = File.OpenWrite("Inventory.dat");

FileStream与StreamWriter不同，但您可以使用

创建StreamWriter

StreamWriter myFile = new StreamWriter(File.OpenWrite("Inventory.dat"));

尝试构建解决方案（调试它）并收到错误，说明.exe丢失了
