ASP.net中上传图片怎么做，请各位高手赐教！本人感激不尽！我写代码了，但是用不起！
String filename, savepath;
String[] tempfilename;
savepath = Server.MapPath("image/");
FileUpload fileupload1 = (FileUpload)FormView1.FindControl("FileUpload1");
filename = fileupload1.FileName;
tempfilename = filename.Split('.');
filename = tempfilename[tempfilename.Length-1];
filename = System.Guid.NewGuid().ToString() + "." + filename;
savepath = savepath + filename;
if(fileupload1.HasFile==true)
{
fileupload1.SaveAs(savepath);
}
Image image1 = (Image)FormView1.FindControl("Image1");
image1.ImageUrl = "~/image/"+filename;
Session["filename"] = filename; --------------------编程问答-------------------- 这里是原文
/// <summary>
/// 在服务器上新建目录
/// </summary>
/// <param name="dir"></param>
protected void createDir(string dir)
{
if (dir.Length == 0) return;
if (!System.IO.Directory.Exists(Request.PhysicalApplicationPath + "\\" + dir))
System.IO.Directory.CreateDirectory(Request.PhysicalApplicationPath + "\\" + dir);
}
/// <summary>

/// <param name="FileUpload1"></param>
/// <param name="txtUrl"></param>
/// <param name="ChannelDir"></param>
protected void setUploadFile(ref FileUpload FileUpload1, ref TextBox txtUrl, string ChannelDir)
{
if (FileUpload1.PostedFile != null)
{
string fileContentType = FileUpload1.PostedFile.ContentType;
if (fileContentType == "image/bmp" || fileContentType == "image/gif" || fileContentType == "image/pjpeg")
{
if (FileUpload1.PostedFile.ContentLength > 1024 * 1024)
{
Alert("上传文件大于1M,请使用FTP上传!");
return;
}
string filename = string.Empty;
string filename2 = FileUpload1.PostedFile.FileName;
filename2 = filename2.Substring(filename2.LastIndexOf('.'));
char[] namechar = DateTime.Now.ToString().ToCharArray();
for (int i = 0; i < namechar.Length; i++)
{
if (namechar[i] != '-' && namechar[i] != ':' && namechar[i] != ' ')
filename += namechar[i].ToString();
}
filename += new Random().Next(100, 999).ToString();
filename += filename2;
string filepath = DateTime.Now.Year.ToString() + DateTime.Now.Month.ToString();
filepath = ChannelDir + "/UserFiles/" + filepath;
createDir(filepath);
FileUpload1.PostedFile.SaveAs(Request.PhysicalApplicationPath + filepath + "/" + filename);
filepath = filepath + "/" + filename;
txtUrl.Text = filepath.ToString().Trim();
}
else
{
Alert("只能上传图片格式！");
}
}
比较简单的上传图片代码 有点过分简化了 看不明白就加群 15058618 --------------------编程问答-------------------- ···其中的Alert是个基类函数 ······ --------------------编程问答-------------------- 帮顶 --------------------编程问答-------------------- 学习 --------------------编程问答-------------------- 这样的代码网上多的事，楼主自己找一下吧
一眼看到的错误是这个
tempfilename[tempfilename.Length-1];
tempfilename是一个数组，而你的[]内的参数是什么啊 --------------------编程问答-------------------- http://www.51aspx.com/Type/6/
看看里面有没有你需要的
补充：.NET技术 , ASP.NET
