人气:0想了解asp.net读取磁盘文件、删除实例代码的相关内容吗，在本文为您仔细讲解asp.net读取磁盘文件、删除的相关知识和一些Code实例，欢迎阅读和指正，我们先划重点：asp.net,磁盘文件，下面大家一起来学习吧。
复制代码 代码如下:
protected void ReadFile() //读取文件夹，文件
{
string savePath = @"common";
StringBuilder outstring = new StringBuilder();
string absSavePath = Server.MapPath(savePath);
string[] Directorys = Directory.GetDirectories(absSavePath + @"/" + Page.User.Identity.Name);
//for (int i = 0; i < Directorys.Length; i++)
//{
// Response.Write(Directorys[i] + " <br/ >");
//}
//Response.Write("Directorys count：" + Directorys.Length + "个 <br/ >--------- <br >");
string[] Files = Directory.GetFiles(absSavePath + @"" + Page.User.Identity.Name, "*");
outstring.Append("<ul>");
for (int i = 0; i < Files.Length; i++)
{
if (Path.GetFileName(Files[i]) != "Thumbs.db")
{
outstring.Append("<li><img src=/"common/" + Path.GetFileName(Files[i]) + "/" style=/"width:100px;height:100px;/" /><br/><input type=/"checkbox/" value=/"common/" + Path.GetFileName(Files[i]) + "/" name=/"picname/" onclick=/"getpicid();/" id=/"imgid" + i.ToString() + "/" /><label for=/"imgid" + i.ToString() + "/">" + Path.GetFileName(Files[i]) + "</label></li>");
}
}
outstring.Append("</ul>");
Response.Write(outstring.ToString());
}
//删除文件
string[] strpicname = Request["imgids"].Split(new char[] { ',' });
for (int i = 0; i < strpicname.Length; i++)
{
File.Delete(Server.MapPath(strpicname[i].ToString()));
}
复制代码 代码如下:
//循环遍历复选框
<script language="javascript" type="text/javascript" defer="defer">
var imgnum = document.getElementsByTagName("input");
var imgids = "";
function getpicid()
{
document.getElementById("hidimgid").value = "";
for (var i=0;i<imgnum.length;i++)
{
if ( imgnum[i].type == "checkbox" && imgnum[i].name == "picname" && imgnum[i].checked)
{
imgids += imgids == "" ? imgnum[i].value : "," + imgnum[i].value;
}
}
document.getElementById("hidimgid").value = imgids;
}
</script>
