我想用asp.net从SQL数据库中检索二进制数据.但是输出中显示的数据与我插入的数据不匹配.这是我的代码:

string EQuery = "SELECT * FROM Ph_Tbl_Contacts WHERE (Contact_ID =" + Contact_ID + ")";

DataSet DSs = new DataSet();
DataTable dt = new DataTable();
DataRow dr = dt.NewRow();

DSs = DB.ExecuteQueryData(EQuery);
dt = DSs.Tables[0];

// dr = dt.NewRow();
dr = dt.Rows[0];
byte[] pic;
byte[] raw = (byte[])dr["Contact_CardImage"];
//  Session[OpenDialog.STORED_IMAGE] = raw ;

这是插入部分:

byte[] IMAGEbYTE ;
IMAGEbYTE = (byte[])(Session["SessionImage"]);
string Query = "INSERT INTO Ph_Tbl_Contacts (Contact_Name, Contact_LName, " + 
               "Contact_Company, Contact_Email, Contact_Tel, " + 
               "Contact_Mobile,Contact_CardImage,Is_Public,User_ID,Save_Date)" + 
               "VALUES (N'" + …
