I have previously written an article about deep learning training skills, which includes some of the assistant experience: Deep learning training experience. However, as a result of the general deep learning experiment, compared to ordinary machine learning tasks, time is longer, so the assistant skills are particularly important. At the same time, personal practice, there are s

Asp.net c file writing function example code StreamWriter and StreamReader write characters to the stream and read characters from the stream. The following code example opens the log.txt file (create a file if the file does not exist) for input and attaches the information to the end of the file. Then write the file content to the standard output for display.

C # When reading and writing a file, the file is being used by another process. Therefore, the process cannot access the file and encounters an I/O failure.
The file "D: \ log.txt" is being used by another process, so the process cannot access the file.
Log.txt is a log file and may be written to it by another program from time to time.
I/O streams need to be used to read log files and display them in log query.

2. Concept of stream:
A stream is an object used to transmit data. Data transmission has two directions:
If the data is transmitted from the external source to the program, this is the read stream; if the data is transmitted from the program to the external source during the summer vacation, This is the write stream.
