使用asp.net或javascript上传图片？ [英] upload images using asp.net or javascript?

问题描述

亲爱的所有人，

上传图片意味着：



在网页中包含：姓名，地址，mobileno，电子邮件，密码，确认密码，图片。



这里输入姓名，地址，mobileno，电子邮件，密码，确认密码



和目前我没有图像，下次上传图像选项后我想要。



这个可选的上传图片示例或逻辑请回复我

解决方案

这很简单

尝试这样的事情：

  if （Fileupload1.PostedFile.ContentLength！=  0 ）
 {
  //   insert with image  
} 
  else  
 {
  //  无图像插入 
} 

和更新获取ID并上传

参考：文件上传控制 [ ^ ]

这是我的fileupload项目代码



试试吧.. :)

 protected void upload_Click（object sender，EventArgs e）
 {
 if（doctorfileupload.PostedFile！= null）
 {
 string FileName = Path.GetFileName（doctorfileupload.PostedFile 。文件名）; 
 Session [filename] = FileName; 
 //doctorfileupload.SaveAs(Server.MapPath(\"~/images2/+ FileName））; 
 string cont_name =; 
 cont_name = doctorfileupload.FileName; 
 string path = Server.MapPath（〜/ BenImages /）; 
 doctorfileupload.SaveAs（path + cont_name）; 
 string FullPath =〜/ BenImages /+ cont_name; 
 Session [pathname] = FullPath; 
 imagedisplay.ImageUrl = FullPath; 
} 
} 
 

Dear All,
Upload images means:

in web page contain: name, address, mobileno,email,password, confirmpassword,image.

here once enter name, address, mobileno,email,password, confirmpassword

and currently i dont have image after next time upload image option i want.

this optional upload image examples or logic please reply me

解决方案

It's pretty simple
Try something like this:

if (Fileupload1.PostedFile.ContentLength != 0)
{
//insert with image
}
else
{
//insert without image
}

and for update get the ID and upload it

Refer: file-upload-control[^]

here is my fileupload project code

try it .. :)

protected void upload_Click(object sender, EventArgs e)
   {
       if (doctorfileupload.PostedFile != null)
       {
           string FileName = Path.GetFileName(doctorfileupload.PostedFile.FileName);
           Session["filename"] = FileName;
           //doctorfileupload.SaveAs(Server.MapPath("~/images2/" + FileName));
           string cont_name = "";
           cont_name = doctorfileupload.FileName;
           string path = Server.MapPath("~/BenImages/");
           doctorfileupload.SaveAs(path + cont_name);
           string FullPath = "~/BenImages/" + cont_name;
           Session["pathname"] = FullPath;
           imagedisplay.ImageUrl = FullPath;
       }
   }
