我在文件player.cs中的CS代码是:
My cs code in file players.cs is:
enter code here
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class AddPlayers : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void ListView1_SelectedIndexChanged(object sender, EventArgs e)
{
}
protected void ListView1_ItemCommand(object sender,ListViewInsertEventArgs e)
{
FileUpload fu2 = (FileUpload)ListView1.InsertItem.FindControl("FileUpload2");
if (fu2.HasFile)
{
string aut = "pol.jpg";
fu2.SaveAs(Server.MapPath("~/images/" + aut.ToString() ));
ErrorLabel1.Text = "ok";
}
else
{
ErrorLabel1.Text = "no";
}
}
}
fileuploader无法正常工作.我不想获取每个上载图像的文件名.我只想获取"SURNAME"字符串并将文件另存为"SURNAME" +".jpg"非常感谢你
The fileuploader is not working. I don't want to get the file name of every image that is uploaded. I only want to get the "SURNAME" string and save file as "SURNAME" +".jpg"thank you very much
推荐答案
我将在标记中附加ItemCommand事件:
I would attach the ItemCommand event in mark up:
<asp:ListView ID="ListView1" runat="server" DataKeyNames="ID,IDOTEAM,IDOCOUNTRY"
DataSourceID="SqlDataSource1" InsertItemPosition="LastItem"
OnItemCommand="ListView1_ItemCommand" >
并在代码中:(已编辑，以反映请求的更改)
protected void ListView1_ItemCommand(object sender, ListViewCommandEventArgs e)
{
if (e.CommandName == "Update")
{
TextBox txtSurName = (TextBox)ListView1.InsertItem.FindControl("SURNAMETextBox");
TextBox txtFirstName = (TextBox)ListView1.InsertItem.FindControl("FIRSTNAMETextBox");
FileUpload fu1 = (FileUpload)ListView1.InsertItem.FindControl("FileUpload1");
if (fu1.HasFile)
{
string aut = String.Format("{0}{1}{3}", txtFirstName.Text, txtFirstName.Text, ".jpg");
fu1.SaveAs(Server.MapPath("~/images/" + aut));
ErrorLabel1.Text = "ok";
}
else
{
ErrorLabel1.Text = "no";
}
}
else if (e.CommandName == "INSERT")
{
TextBox txtSurName = (TextBox)ListView1.InsertItem.FindControl("SURENAMETextBox");
TextBox txtFirstName = (TextBox)ListView1.InsertItem.FindControl("TextBox1");
FileUpload fu2 = (FileUpload)ListView1.InsertItem.FindControl("FileUpload2");
if (fu2.HasFile)
{
string aut = String.Format("{0}{1}{3}", txtFirstName.Text, txtFirstName.Text, ".jpg");
fu2.SaveAs(Server.MapPath("~/images/" + aut));
ErrorLabel1.Text = "ok";
}
else
{
ErrorLabel1.Text = "no";
}
}
}
我也强烈建议遵循一些命名惯例:什么是ASP.NET控件的命名准则?.
I would also strongly recommend to follow some naming convension:What are the naming guidelines for ASP.NET controls?.
