上传文件不保存在数据库中

问题描述

尝试上传文件并保存在目录和数据库中，当我上传文件时，它保存在目录中但不在数据库中这里是上传文件代码

try to upload document and save in directory and in database also when i upload document it saves in directory but not in database here is upload document code

if (FileUploadControl.PostedFile != null && FileUploadControl.PostedFile.ContentLength
  < 102400)
        {
            string filename = Path.GetFileName(FileUploadControl.PostedFile.FileName);
            string folder = Server.MapPath("~/Docfiles/");
            Directory.CreateDirectory(folder);
            FileUploadControl.PostedFile.SaveAs(Path.Combine(folder, filename));
            try
            {
                up.fileupladdd(Txt_docde.Value, txt_dname.Value,
             FileUploadControl.FileName, Convert.ToInt32(DropDownList1.SelectedValue),
            Convert.ToInt32(DropDownList2.SelectedValue),
            Convert.ToInt32(Session["UserID"]),Convert.ToString(Session["UserID"]));
                StatusLabel.Text = "Success";
            }
            catch
            {
                StatusLabel.Text = "Failed";
            }
        }


        Txt_docde.Value = "";
        txt_dname.Value = "";

和sp上传文件是

and sp of upload file is

ALTER procedure [dbo].[fileuplaod]
   @DocDesciption nvarchar(50),
   @DocName nvarchar(50),
   @Uploadfile nvarchar(50),
  @DocTypeID int,
  @DepID int,
  @UserID int
 as
 insert into DocumentInfo(DocDesciption ,DocName,Uploadfile,DocTypeID,DepID ,UserID)
  values(@DocDesciption,@DocName,@Uploadfile,@DocTypeID,@DepID ,@UserID)

where出现问题？

where is the problem occur?

推荐答案

SqlConnection PubsConn = new SqlConnection
   ("your connection string here");
SqlCommand testCMD = new SqlCommand
   ("fileuplaod", PubsConn);

testCMD.CommandType = CommandType.StoredProcedure;

SqlParameter DocDesc = testCMD.Parameters.Add
   ("@DocDesciption", SqlDbType.NVarChar, 50);
DocDesc.Direction = ParameterDirection.Input;
SqlParameter DocName= testCMD.Parameters.Add
   ("@DocName ", SqlDbType.NVarChar, 50);
DocName.Direction = ParameterDirection.Input;
// Add other parameters as well

DocDesc.Value = "set document description here";
DocName.Value = "set document name here";
//set other parameter values here

PubsConn.Open();

testCMD.ExecuteNonQuery ().ToString() ;

Convert.ToInt32(Session["UserID"]),Convert.ToString(Session["UserID"]));

这里存在错误，因为你发送了两次相同的参数而你的方法只有6个参数

the error exist here because you send the same argument twice and your method has 6 paramater only

public void fileupladdd(string DocDesc, string Docname, string file, int doctypeid, int depid, int UserID, string UploadedBy)
       {
           //db.ExecuteNonQuery("fileuplaod", new object[] { DocDesc, Docname, file, doctypeid, depid, UserID, UploadedBy });
           Hashtable hash = new Hashtable();
           hash.Add("@DocDesc", DocDesc);
           hash.Add("@Docname", Docname);
           hash.Add("@file", file);
           hash.Add("@doctypeid", doctypeid);
           hash.Add("@depid", depid);
           hash.Add("@UserID", UserID);
           hash.Add("@UploadedBy", UploadedBy);
           ExecuteStoreProcedure("youspname here", hash);


       }

       public int ExecuteStoreProcedure(string spName, Hashtable param)
       {
           try
           {
               using (_DbConn = new SqlConnection(_sConString))
               {
                    _DbConn.Open();
                    SqlCommand _DbCommand = new SqlCommand();
                   _DbCommand.CommandText = spName;
                   _DbCommand.CommandType = CommandType.StoredProcedure;
                   _DbCommand.Connection = _DbConn;
                   foreach (string para in param.Keys)
                   {
                       _DbCommand.Parameters.AddWithValue(para, param[para]);
                   }
                   return _DbCommand.ExecuteNonQuery();
               }
           }
           catch (Exception)
           {

               throw;
           }
       }
