I have some error messages while importing data from excel to sql while using this topic.

https://www.aspsnippets.com/Articles/Read-and-Import-Excel-Sheet-into-SQL-Server-Database-in-ASP.Net.aspx

At first, I took this error "System.IO.DirectoryNotFoundException: Could not find a part of the path ..."

Then I've changed the code like this; string FolderPath = ConfigurationManager.AppSettings["FolderPath"]; string FolderPath = ConfigurationManager.AppSettings[@"\FolderPath"];

Line 69:                 string FolderPath = ConfigurationManager.AppSettings["FolderPath"];
Line 70:                 string FilePath = Server.MapPath(FolderPath + FileName);
Line 71:                 FileUpload1.SaveAs(FilePath);
Line 72:                 GetExcelSheets(FilePath, Extension, "Yes");

I've added "@" and "/" It worked for uploading file. I passed 2. step. and there I took another error message.

"Could not find stored procedure 'spx_ImportFromExcel07'."

I've executed the four statements one by one in the SQL Server Query Analyzer in that article written. But nothing's changed.

Where should I look at? Here is the code that I am using.

        protected void btnUpload_Click(object sender, EventArgs e)
        {
            if (FileUpload1.HasFile)
            {
                string FileName = Path.GetFileName(FileUpload1.PostedFile.FileName);
                string Extension = Path.GetExtension(FileUpload1.PostedFile.FileName);
                string FolderPath = ConfigurationManager.AppSettings[@"\FolderPath"];
                string FilePath = Server.MapPath(FolderPath + FileName);
                FileUpload1.SaveAs(FilePath);
                GetExcelSheets(FilePath, Extension, "Yes");
            }
        }
        private void GetExcelSheets(string FilePath, string Extension, string isHDR)
        {
            string conStr = "";
            switch (Extension)
            {
