INSERT錯誤使用C＃/ Asp.Net/SQL RSS

Question

我試圖插入使用sqlparameters數據到數據庫中，但我無法做到這一點..請幫助我..

a = "insert into Matsamp values(Login_Name,Password,Confirm_Password) values(@LName,@Pswd,@CPassword)"; 
     SqlCommand cm = new SqlCommand(a, con1); 
     SqlParameter Uparm; 
     Uparm = new SqlParameter("@LName", SqlDbType.VarChar, 25); 
     Uparm.Value = TextBox1.Text; 
     cm.Parameters.Add(Uparm); 

     string original; 
     original = TextBox2.Text.Trim(); 
     int h = original.GetHashCode(); 
     string withHash = original; 
     b1 = Encoding.BigEndianUnicode.GetBytes(withHash); 
     encrypted = Convert.ToBase64String(b1); 
     SqlParameter Pparam; 
     Pparam = new SqlParameter("@Pswd", SqlDbType.VarChar, 300); 
     Pparam.Value = Convert.ToString(encrypted); 
     cm.Parameters.Add(Pparam); 

     SqlParameter CPparm; 
     CPparm = new SqlParameter("@CPassword", SqlDbType.VarChar, 300); 
     CPparm.Value = TextBox3.Text; 
     cm.Parameters.Add(CPparm); 
     cm.ExecuteNonQuery(); 
     Response.Write("<Script>alert('inserted')</script>"); 
    } 
     con1.Close(); 

Answer 1

您查詢是錯誤的：大概應該是

a = "insert into Matsamp(Login_Name,Password,Confirm_Password) 
    values(@LName,@Pswd,@CPassword)"; 

而且你可以使用

cm.Parameters.AddWithValue("@LName", TextBox1.Text); 
cm.Parameters.AddWithValue("@Pswd", ...); 
cm.Parameters.AddWithValue("@CPassword", ...); 

把它縮短。
