my code is:

C#

    {
      
            string[] result=new string [4];
            string accessnumber = null;
            accessnumber = "";
            result = clsObj.FnCheckAccessNo();

            if (result[0] == "1")
            {
                accessnumber = result[2];

       string[] result = new string[2];
       string[] spexec = new string[2];

       string[] inputparaname = { "@Accountnumber", "@AccessNo", "@DestNo", "@name_of_diverison" };
       string[] inputparavalue = { Account, AccNo, DestNo, DestRef };

       string[] outputparaname = { "@result" };



       spexec = fnProcessStoredProc("Update_AccessNumber", sqlconn_cmsstr, inputparaname, inputparavalue, outputparaname);


       if (spexec[0] == "1" && spexec[1] == "1")
       {
           //successful login

your FnUpdatedAccessNo methods first parameter is string. but Session["User_id"] is an object type. you must to convert it like this.
And dont forget when it was null it wont convert, check its nullable

C#

string userId = "";
if(Session["User_id"] != null)
userId = Session["User_id"].ToString();
else userId = "";// default value 
result1 = clsObj.FnUpdatedAccessNo(userId, accessnumber, TextBoxDest.Text.Trim(), TextBoxRef.Text.Trim());
