asp.net生成静态文件-优快云博客

本文介绍了一个ASP.NET中的文件读写示例，包括如何使用C#代码创建新的HTML文件，并从模板文件中读取内容进行替换。此外，还展示了如何读取特定文件的内容。

public static bool WriteFile(string strText, string strContent, string strAuthor)
{

string path = HttpContext.Current.Server.MapPath("~/news/");

Encoding code = Encoding.GetEncoding("gb2312");

// 读取模板文件

string temp = HttpContext.Current.Server.MapPath("~/news/text.htm");

StreamReader sr = null;

StreamWriter sw = null;

string str = "";

        try
        {
            sr = new StreamReader(temp, code);
            str = sr.ReadToEnd(); // 读取文件
        }
        catch (Exception exp)
        {
            HttpContext.Current.Response.Write(exp.Message);
            HttpContext.Current.Response.End();
            sr.Close();
        }

string htmlfilename = DateTime.Now.ToString("yyyyMMddHHmmss") + ".html";

// 替换内容

// 这时,模板文件已经读入到名称为str的变量中了

        str = str.Replace("{ShowArticle}", strText); //模板页中的ShowArticle
        //str = str.Replace("{biaoti}", strText);
        //str = str.Replace("{content}", strContent);
        //str = str.Replace("{author}", strAuthor);

        // 写文件
        try
        {
            sw = new StreamWriter(path + htmlfilename, false, code);
            sw.Write(str);
            sw.Flush();
        }
        catch (Exception ex)
        {
            HttpContext.Current.Response.Write(ex.Message);
            HttpContext.Current.Response.End();
        }
        finally
        {
            sw.Close();
        }
        return true;
    }

        sr.Close();
        return str;
    }
