2.HtmlInputFiles控件运用
下图为该控件使用中的截图
“添加上传”按钮用来增加上传附件，“减少上传”按钮用来减少上传附件。
具体使用如下:
前台代码：
<div>
<cc1:HtmlInputFiles ID="HtmlInputFiles1" runat="server" AddButtonVisible="True" MaxCount="15" RecordCount="1" FileFilter=".GIF|.JPG|.JPEG|.RAR|.TXT" />
<br />
<asp:Button ID="BtnUpfile" runat="server" onclick="BtnUpfile_Click" Text="上 传" />
</div>
<cc1:HtmlInputFiles ID="HtmlInputFiles1" runat="server" AddButtonVisible="True" MaxCount="15" RecordCount="1" FileFilter=".GIF|.JPG|.JPEG|.RAR|.TXT" />
<br />
<asp:Button ID="BtnUpfile" runat="server" onclick="BtnUpfile_Click" Text="上 传" />
</div>
后台代码：
protected void BtnUpfile_Click(object sender, EventArgs e)
{
if (this.HtmlInputFiles1.CheckAllPostedFile(true))
{
for (int i = 0; i <= this.HtmlInputFiles1.RecordCount; i++)
{
System.IO.FileInfo info = new FileInfo(this.HtmlInputFiles1[i].PostedFile.FileName);
string fileName = info.Name;
string filePath = "UpLoads/" + System.Guid.NewGuid().ToString() + fileName;
this.HtmlInputFiles1[i].PostedFile.SaveAs(Server.MapPath(filePath));
}
}
}
{
if (this.HtmlInputFiles1.CheckAllPostedFile(true))
{
for (int i = 0; i <= this.HtmlInputFiles1.RecordCount; i++)
{
System.IO.FileInfo info = new FileInfo(this.HtmlInputFiles1[i].PostedFile.FileName);
string fileName = info.Name;
string filePath = "UpLoads/" + System.Guid.NewGuid().ToString() + fileName;
this.HtmlInputFiles1[i].PostedFile.SaveAs(Server.MapPath(filePath));
}
}
}
