In summary, File,fileinfo,filestream is the class used for file I/O, and StreamReader is the class used to read from and write to the stream, using System.IO before use.Define a TXT document path First: string Txtpath = (@ "d:\c# exercise \1.txt"); To read into this document.(1) File provides static methods for creating, copying, deleting, moving, and opening files, and assists in creating FileStream.FileStream fs = File.Open (Txtpath, FileMode.Open);
Programming access files are carried out through file stream objects, when the application Program To access a file, you must first create a file stream object, which corresponds to the file. In. net, the abstract base class system. Io. stream is used to represent the stream. It provides two methods: read and write. Due to the orderliness of the data stream, the stream object also has a read/write pointer. For this reason, the stream class also has a seek Method for moving read/write pointers.

Q: I use form-based authentication in ASP. NET applications. I want to use FileStream (file stream), but verification becomes a barrier. How can I set it? A:If you are using anonymous access and form-based authentication, you cannot combine them with Windows users. Therefore, you cannot verify Windows users from web clients in SQL Server. The solution is to use IIS process-level identity to log on to SQL Server with integrated security. Even if you ac
