Lua读取和写入文件处理例子

function SaveTableContent(file, obj)
      local szType = type(obj);
      print(szType);
      if szType == "number" then
            file:write(obj);
      elseif szType == "string" then
            file:write(string.format("%q", obj));
      elseif szType == "table" then
            --把table的内容格式化写入文件
            file:write("{\n");
            for i, v in pairs(obj) do
                  file:write("[");
                  SaveTableContent(file, i);
                  file:write("]=\n");
                  SaveTableContent(file, v);
                  file:write(", \n");
             end
            file:write("}\n");
      else
      error("can't serialize a "..szType);
      end
end

function SaveTable()
      local file = io.open("e:\\00_00_00_海外组_学习\\写入.txt", "w");
      assert(file);
      file:write("cha = {}\n");
      file:write("cha[1] = \n");
      SaveTableContent(file, cha[1]);
      file:write("}\n");
      file:close();
end

SaveTable();
