file upload

hi,

for that create a table in sql server.

id  int(set identity)
filename  varchar(50)
filetype varchar(50)
filesize int

in front end insert these values to database table.

to get file extension use below code:

 FileInfo fi = new FileInfo(filename);
  string ext = fi.Extension;

to get file size use below code:

int fileSize = FileUploadControl.PostedFile.ContentLength;

now save these data in database.

sample:

  protected void UploadButton_Click(object sender, EventArgs e)
    {
        if (FileUploadControl.HasFile)
        {
            try
            {
                string filename = Path.GetFileName(FileUploadControl.FileName);
                int fileSize = FileUploadControl.PostedFile.ContentLength;
                FileInfo fi = new FileInfo(filename);
                string ext = fi.Extension;
                FileUploadControl.SaveAs(Server.MapPath("~/") + filename);
                SqlConnection con = new SqlConnection("your connection string");
                con.Open();
                SqlCommand cmd = new SqlCommand("insert into FilesTable(filename,filetype,filesize) values(@Name,@type,@size)", con);
                cmd.Parameters.AddWithValue("@Name", filename);
                cmd.Parameters.AddWithValue("@type", ext);
                cmd.Parameters.AddWithValue("@size", fileSize);
                cmd.ExecuteNonQuery();
                con.Close();

            }
            catch (Exception ex)
            {
                Response.Write(ex.Message);
            }
        }
