数据库连接字符串，分别取得用户名，密码等参数

            string connect = DataModal.Properties.Settings.Default.StockManageSystemConnectionString;
            Dictionary<string, string> dictionary = connect.Split(new char[] { ';' }, StringSplitOptions.RemoveEmptyEntries).ToDictionary(x => x.Split('=')[0], x => x.Split('=')[1]);
            foreach (KeyValuePair<string, string> pair in dictionary)
                Console.WriteLine(pair.Key + ":" + pair.Value);
            Console.WriteLine("uid的值是：" + dictionary["uid"]);

connect 是连接字符串。

但是如果分别取到，分别赋值的话，应该首先完成上面，然后根据new一个List存相应需要的值。
demo:

            string connect = DataModal.Properties.Settings.Default.StockManageSystemConnectionString;
            Dictionary<string, string> dictionary = connect.Split(new char[] { ';' }, StringSplitOptions.RemoveEmptyEntries).ToDictionary(x => x.Split('=')[0], x => x.Split('=')[1]);
            List<string> test = new List<string>(dictionary.Values);
            for (int i = 0; i < test.Count; i++)
            {
                Server.Text = test[0];
                Sqlname.Text = test[2];
                Pass.Text = test[4];
                Account.Text = test[3];
            }
