使用該介面完成資料庫伺服器的連線配置，給使用者提供一個方便、友好、易操作的介面。

首次配置成功後，下次登入就直接使用已配置連線登入。

如果需要更改另外的連線，可以直接將程式中的xxxx.exe.config檔案刪除。

用此登入介面結合開發的主程式執行。並設定好程式依賴關係。

以下為詳細說明：

1、配置介面

這個介面用到了DevComponents.DotNetBar外掛。

步驟：

1）下載DevComponents.DotNetBar2.dll（VS2010需要v10.0以上版本）

2）為工程新增引用，瀏覽找到DevComponents.DotNetBar2.dll

3）程式碼中新增using DevComponents.DotNetBar;

下載地址網上很容易找到，這裡提供一個：http://www.pc6.com/softview/SoftView_95579.html

2、用到的類

1）ConfigType.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ServerTest.AppConfig
{
    public enum ConfigType
    {
        /// <summary> 
        /// asp.net網站的config檔案 
        /// </summary> 
        WebConfig = 1,
        /// <summary> 
        /// Windows應用程式的config檔案 
        /// </summary> 
        ExeConfig = 2
    }
}
