重用类fileOpr.cs：
fileOpr.ReadFileContentToArrayList(filepath);中的方法：
public static ArrayList ReadFileContentToArrayList(string filepath)
{
ArrayList al = new ArrayList();
FileStream fs = new FileStream(filepath, FileMode.Open, FileAccess.Read);
StreamReader srd = new StreamReader(fs, Encoding.Default);
//使用StreamReader类来读取文件
srd.BaseStream.Seek(0, SeekOrigin.Begin);
string strLine = srd.ReadLine();
while (strLine != null)
{
strLine = srd.ReadLine();
al.Add(strLine + "\n");
}
//关闭此StreamReader对象
srd.Close();
fs.Dispose();
fs.Close();
return al;
}
注：有种文章分页的思路是用截取文本字符数的方法来处理，这个方法当文章内容是html代码的话，分页后会引起排版问题。
上面代码的方法思路是按行数来处理，这个方法个人认为相对更好些。在后台管理文章内容文件时，保证html代码的良好排版换行即可。

RTX 5090要首发 性能要翻倍！三星展示GDDR7显存
三星在GTC上展示了专为下一代游戏GPU设计的GDDR7内存。
首次推出的GDDR7内存模块密度为16GB，每个模块容量为2GB。其速度预设为32 Gbps（PAM3），但也可以降至28 Gbps，以提高产量和初始阶段的整体性能和成本效益。
据三星表示，GDDR7内存的能效将提高20%，同时工作电压仅为1.1V，低于标准的1.2V。通过采用更新的封装材料和优化的电路设计，使得在高速运行时的发热量降低，GDDR7的热阻比GDDR6降低了70%。
