在Lua中,可以使用io庫(kù)來(lái)進(jìn)行文件讀寫(xiě)操作。以下是一些常用的文件讀寫(xiě)操作示例:

  1. 讀取文件內(nèi)容:
local file = io.open("file.txt", "r")
if file then
  local content = file:read("*a")
  print(content)
  file:close()
else
  print("Error: Unable to open file")
end
  1. 寫(xiě)入內(nèi)容到文件:
local file = io.open("file.txt", "w")
if file then
  file:write("Hello, world!")
  file:close()
else
  print("Error: Unable to open file")
end
  1. 追加內(nèi)容到文件:
local file = io.open("file.txt", "a")
if file then
  file:write("\nThis is a new line")
  file:close()
else
  print("Error: Unable to open file")
end

在進(jìn)行文件讀寫(xiě)操作時(shí),需要確保文件的讀寫(xiě)權(quán)限并在操作完成后關(guān)閉文件流。
