created. Read content from a file Reading content from a file is roughly the same as writing content to the file, but pay attention to the following two things: 1. Use the streamreader class for File Reading 2. When the Readline method is used, an empty string ("") is used to mark the end of the text file to be read. The write code is now used to read the content from the aspnet.txt file created earlier: In ASP. NET, the entire process of file processing is centered around the namespace s

A few days ago, I/O processing encountered a problem that could not be operated.The file "D: \ log \ cargoabc \ logfilecargoabc.txt" is being used by another process. Therefore, this process cannot access the file.Logfilecargoabc.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.1. filestream FS = file. openread (URL );Streamreader sr = new streamreader (system. Io. Stream) FS, system. Text.

1. It is convenient to write --------- to cells one by one, but the speed is slow. 2. Using the Excel feature, the data in each column is first separated by \ t, each row is separated by \ r \ n, and finally pasted to the clipboard ---------- with a slightly higher speed, however, if a copy and paste task is executed externally, errors may occur. 3. assign values directly to the corresponding area of the array through arrays. ---------- Very convenient for datatable. You can assign a value dir
