                    UploadedImage.Value = image;
                    cmd.Parameters.Add(UploadedImage);
                    cmd.Connection = cn;
                    cmd.ExecuteNonQuery();
                    uploadcollogo.SaveAs(Server.MapPath("../userside/collogo/") + uploadcollogo.FileName);
                   // uploadcollogo.SaveAs(Server.MapPath(image1));
                    cn.Close();
                    clear();
                    Page.ClientScript.RegisterStartupScript(this.GetType(), "Inserted", "<script>alert('Record Inserted Sucessfuly')</script>");

                
            }

推荐答案

尝试一下

try this

string ServerSavePath = Server.MapPath("~/Upload");
           string path = Path.Combine(ServerSavePath, fileName);
