DotNET 长文章分页方法

 

自己写的一个长文章分页：

用的时候只要传入三个参数：文章的内容；文章显示页面的链接；每页估计显示的字数；

该方法不会截断HTML的标签。

 

Code
        #region 长文章分页方法
/// <summary>
/// 长文章分页方法
/// </summary>
/// <param name="content">整篇文章的所有内容</param>
/// <param name="url">文章显示页的路径</param>
/// <param name="contenLength">每页预计的字数</param>
/// <returns>每页的内容</returns>

        {

string _tempString = "";
if(content.Length<contenLength)
            {
                newContentArray.Add(content);
            }
else
            {

                {
                    _tempString += contentArray[i];
