问题描述

protected void btnSave_Click1(object sender, EventArgs e)
{
    List<string> img=new List<string>();
    HttpFileCollection httpFileCollection = Request.Files;
    for (int i = 0; i < httpFileCollection.Count; i++)
    {
        HttpPostedFile httpPostedFile = httpFileCollection[i];
        string fileNameExtension = Path.GetFileName(httpPostedFile.FileName);
        if (httpPostedFile.ContentLength > 0)
        {
            httpPostedFile.SaveAs(Server.MapPath("~/Upload/Testimonial/")+ "\\"+ fileNameExtension);
            img.Add(Server.MapPath("~/Upload/Testimonial/") + Path.GetFileName(FileUpload1.PostedFile.FileName));
        }
        

    }
    if (btnSubmit.Text == "Submit")
    {
        bool a = video.SaveUpdatetestimonial(1, Editor.Content, img.ToArray().Length > 0 ? string.Join(",", img.ToArray()) : Path.GetFileName(FileUpload1.FileName), txtEmbed.Text, TextBox1.Text, 0);
        if (a == true)
        {
            txtEmbed.Text = "";
            TextBox1.Text = "";
            Editor.Content = "";
            lblInfo.Text = "Record Inserted Successfully";
            BindGrid(1);
        }
        else
        {
            lblInfo.Text = "Record not Saved";
        }
    }
    else
    {
        if (btnSubmit.Text == "Update")
        {
            int Sno = Convert.ToInt32(grdImg.Rows[temp].Cells[1].Text);
            bool a = video.SaveUpdatetestimonial(2, Editor.Content, img.ToArray().Length > 0 ? string.Join(",", img.ToArray()) : System.IO.Path.GetFileName(FileUpload1.FileName), txtEmbed.Text, TextBox1.Text,Sno);
            if (a == true)
            {
                txtEmbed.Text = "";
                Editor.Content = "";
                lblInfo.Text = "Record Updated";
                BindGrid(1);
                TextBox1.Text = "";
            }
            else
            {
                lblInfo.Text = "Record Not Updated";
            }
        }
    }
}

错误是什么？所以它只存储最后选择的图像。帮助我，提前谢谢

what is error in it ? so it is storing only last selecting image. Help me, Thanks in advance

推荐答案

对于此代码，将文件名创建为变量，然后将其添加到集合中。在2行中，您使用了来自2个不同项目的2个不同名称

For this code, create file name as variable and then add it to the collection. In 2 lines you have used 2 different names coming out of 2 different items

httpPostedFile.SaveAs(Server.MapPath("~/Upload/Testimonial/")+ "\\"+ fileNameExtension);
            img.Add(Server.MapPath("~/Upload/Testimonial/") + Path.GetFileName(FileUpload1.PostedFile.FileName));

第一行来自httpPostedfFile，另一行来自FileUpload控件。所以这是一个矛盾。文件上传控件将始终具有单个文件名，因此它将是重复输入。



使用saparate变量而不是内联代码将清除代码并提供帮助调试断点

First line is taking from httpPostedfFile and another is taking from FileUpload control. So this is a contradiction. The file upload control will always have a single file name so it will be a repeated entry.

Having saparate variables instead of inline code will clear out the code and help with debugging breakpoints as well
