Web Forms :: No Overload For Method GetImagess Takes 2 Arguments Error

Into below code i am using it to check if the user  had uploaded images before or not if yes then keep the old and update if the user has new files into fileuploads controls.

But what i am looking for to update the code and delete UID and use AdsID column  " column data type is: Int" which is passed by query string QADNUM.

I tried to delete UID and use QADNUM instaed of UID but it dosent work and i tried to add QADNUM but i faced an error with code line:

 string[] images = GetImagess(Convert.ToString(QADNUM), QADNUM); 

The error message with below line under the above line : No overload for method 'GetImagess' takes 2 arguments

private string[] GetImagess(string UID) {
string QADNUM = Request.QueryString["AID"];
SqlConnection EdPersInfoCon = new SqlConnection(ssc);
EdPersInfoCon.Open();
SqlCommand EdPersInfocmd = new SqlCommand();
