Dropdown value coming blank but still going in IF condition

While submitting a form, I am not selecting any value from the dropdownlist and I am checking condition as

if (Request.Form["CmbNextUser"] != Session["UserId"].ToString() || Request.Form["CmbNextUser"] != null || Request.Form["CmbNextUser"] != "")
        {
            TransferMail();
        }

So, while debugging my value comes as like below.

IMG

The value is coming blank but still it is going in the IF condition

Your IF conditions have logical ORs between them. This means if any one of them are met, the whole thing will execute. Did you mean to use && (and) instead of || (or).

  1. Condition one is causing for this since you are comparing value 

     Request.Form["CmbNextUser"] != Session["UserId"].ToString()

    i.e "" != Session["UserId"].ToString() which is evaluated as ture thats why it it executing if block.

  2. Change code like this

    if (!String.IsNullOrEmpty(Request.Form["CmbNextUser"]) || Request.Form["CmbNextUser"] != Session["UserId"].ToString() )
{
    TransferMail();
}
