ASP.net MS訪問像查詢不工作使用asp.net c＃

Question

所有喜歡查詢doesnot工作請幫助我，下面是我的代碼。

string Item_Name = txt_search.Text.Trim(); 
string Conn = ConfigurationManager.ConnectionStrings["AjitConnectionString"].ToString(); 
OleDbConnection con = new OleDbConnection(Conn); 
con.Open(); 
OleDbCommand cmd; 
cmd = new System.Data.OleDb.OleDbCommand("select * from [Item] where [Name] like '*'+inamer_Name+'*'", con); 
cmd.Parameters.AddWithValue("@inamer_Name", Item_Name); 
cmd.ExecuteNonQuery(); 
OleDbDataAdapter da = new OleDbDataAdapter(cmd); 
DataTable dt = new DataTable(); 
da.Fill(dt); 
grid_itemedit.DataSource = dt; 
grid_itemedit.DataBind(); 
con.Close(); 

Answer 1

通配符字符是比較字符串的一部分。
For example：

像 'B *'
結果：以b開頭的所有值

cmd = new System.Data.OleDb.OleDbCommand("select * from [Item] where [Name] like '%" + inamer_Name + "%'", con);
