使用XSLT制作HTML邮件模板并发送
之前有写过能发送邮件的小工具，基本做法就是先在代码中写死一封HTML邮件的格式，然后用适当的方法取得外部的几个值填到预设的参数里，最后把合体后的string类型邮件发出去。简单的邮件还好，当内容稍微多一点，比如输出数据库的一个表，又或者邮件格式经常要变动的，就感觉很麻烦很受拘束。
后来看到了别人用XSLT做的一个邮件模板，很受启发。自己也尝试了一下，就有了这篇文章。
下面这个方法是从数据库里搜索符合条件的数据（列出由指定用户管理并且已经超过有效期限的文档，以XML形式导出），然后使用指定的xslt文件格式化取得的XML格式数据。
///<summary>
///生成邮件内容
///</summary>
///<param name="date">预定删除日期</param>
///<param name="account">管理者ID</param>
privatestring GetSendMailBoby(DateTime
date,string account)
{
using (conn =newSqlConnection(
ConfigurationManager.ConnectionStrings["mainDB"].ConnectionString))
{
conn.Open();
string bodyString =string.Empty;
string commString =string.Empty;
commString +="SELECT item_name,item_url,parent_url FROM DocAddress ";
commString +="WHERE manger_id=@account AND due_date<=@executedate AND ";
commString +="send_flg = 0 FOR XML AUTO, ELEMENTS,ROOT('SendmailToUser')";
SqlCommand command =newSqlCommand(commString,
conn);
command.Parameters.AddWithValue("@account", account);
command.Parameters.AddWithValue("@executedate", date);
using (XmlReader reader = command.ExecuteXmlReader())
{
XslCompiledTransform transform =new System.Xml.Xsl.XslCompiledTransform();
transform.Load(
Application.StartupPath +@""" +ConfigurationManager.AppSettings["Mail.Template"]
);
XsltArgumentList argList =newXsltArgumentList();
argList.AddParam("deleteday","", date.AddDays(14).ToLongDateString());
using (StringWriter writer =newStringWriter())
{
transform.Transform(reader, argList, writer);
bodyString = writer.ToString();
}
}
conn.Close();
return bodyString;
}
}
