datagridview急急急

动心倾听

[C#] 纯文本查看 复制代码

string sql = "select * from Account";
                adapter = new SqlDataAdapter(sql, conn);
                ds = new DataSet();
                adapter.Fill(ds, "User");
                //对输入的密码加密验证
                byte[] pwd = Encoding.Default.GetBytes(frmAdd.txtPassWord);
                MD5 md5 = new MD5CryptoServiceProvider();
                byte[] output = md5.ComputeHash(pwd);
                string proveMd5 = BitConverter.ToString(output).Replace("-", "");
                DataRow row = ds.Tables["User"].NewRow();
                row[1] = frmAdd.txtUserName;
                row[2] = proveMd5;
                row[3] = frmAdd.txtJob;
                row[4] = frmAdd.txtNote;
                row[5] = frmAdd.txtCreateTime;
                ds.Tables["User"].Rows.Add(row);
                if (ds.HasChanges())
                {
                    SqlCommandBuilder builder = new SqlCommandBuilder(adapter);
                    adapter.Update(ds.Tables["User"]);
                    ds.Tables["User"].AcceptChanges();
                }
                dgvUsers.DataSource = ds;

踏风无痕

dgvUsers.Databind()  ???

站长苏飞

你这个Cs还是Bs啊，BS的还是需要执行这个方法的dgvUsers.Databind()
