<asp:FileUpload ID="FileUpload" runat="server" /> private string upLoad() { string path=""; string filepath = FileUpload.PostedFile.FileName; string fileName = filepath.Substring(filepath.LastIndexOf("\\") + 1); path = Server.MapPath(@"~/files/") + filepath; string filePath = "~/files/" + fileName; Response.Write(filePath); FileUpload.SaveAs(path); return filePath; }
第二种方法,大致是一样的
protected void btnUpload_Click(object sender, EventArgs e) { if (FileUpload1.HasFile) { string fileExt = System.IO.Path.GetExtension(FileUpload1.FileName); if (fileExt == ".jpg" || fileExt == ".gif") { try { FileUpload1.SaveAs(Server.MapPath("/ScenicImg")+"\\" + FileUpload1.FileName); Label1.Text = "客户端路径:" + FileUpload1.PostedFile.FileName + "<br>" + "文件名:" + System.IO.Path.GetFileName(FileUpload1.FileName) + "<br>" + "文件扩展名:" + System.IO.Path.GetExtension(FileUpload1.FileName) + "<br>" + "文件大小:" + FileUpload1.PostedFile.ContentLength + " KB<br>" + "文件MIME类型:" + FileUpload1.PostedFile.ContentType + "<br>" + "保存路径:" + Server.MapPath("/ScenicImg") + "\\" + FileUpload1.FileName; } catch (Exception ex) { Label1.Text = "发生错误:" + ex.Message.ToString(); } } else { Label1.Text = "只允许上传jpg、gif文件!"; } } else { Label1.Text = "没有选择要上传的文件!"; } }
