用Asp.Net上传文件,首用到的是FileUpload控件
<asp:FileUpload ID="FileUpload1" runat="server" /><br />
<asp:Button ID="btn" runat="server" Text="确定" OnClick="btn_Click"/>
C#代码
protected void btn_Click(object sender, EventArgs e)
{
//判断是否选择了文件
if (this.FileUpload1.HasFile)
{
try{
//获取文件
HttpPostedFile filename = this.FileUpload1.PostedFile;
//判断文件大小,字节为单位
if (filename.ContentLength>0)
{
FileUpload1.SaveAs(@"D:\" + FileUpload1.FileName);
s_alert("上传成功");
}
}
catch (Exception ex)
{
s_alert ("上传失败,出现错误");
}
}
else
{
s_alert("你还没有选择文件");
}
}
public static void s_alert(string str)
{
Page page = (Page)HttpContext.Current.Handler;
page.ClientScript.RegisterStartupScript(page.GetType(), Guid.NewGuid().ToString(), "alert('" + str + "');", true);
}
