In C#, the FileStream class is used for reading and writing files. Here are some common usage methods:<\/p>\n

    \n
  1. Create a FileStream object.<\/li>\n<\/ol>\n
    FileStream fileStream = new<\/span> FileStream(\"example.txt\"<\/span>, FileMode.OpenOrCreate);\r\n<\/code><\/pre>\n
      \n
    1. Read the content of the file:<\/li>\n<\/ol>\n
      byte<\/span>[] buffer = new<\/span> byte<\/span>[1024<\/span>];\r\nint<\/span> bytesRead = fileStream.Read(buffer, 0<\/span>, buffer.Length);\r\nstring<\/span> content = Encoding.UTF8.GetString(buffer, 0<\/span>, bytesRead);\r\n<\/code><\/pre>\n
        \n
      1. Write the content to a file.<\/li>\n<\/ol>\n
        string<\/span> content = \"Hello, world!\"<\/span>;\r\nbyte<\/span>[] buffer = Encoding.UTF8.GetBytes(content);\r\nfileStream.Write(buffer, 0<\/span>, buffer.Length);\r\n<\/code><\/pre>\n
          \n
        1. Close the FileStream object.<\/li>\n<\/ol>\n
          fileStream.Close();\r\n<\/code><\/pre>\n
          When using FileStream, it is important to make sure to promptly close the file stream after the operation is complete to release resources. Additionally, resources can also be automatically released using the using statement, as shown below:<\/p>\n
