以前做Winform程序，居然专门做一个界面来配置连接字符串。今天无意中发现：竟然可以直接调用VS.net2005中的配置界面来处理。

使用方法也非常简单：

引用C:\Program Files\Microsoft Visual Studio 8\Common7\IDE 里面的Microsoft.Data.ConnectionUI.Dialog.dll。

using Microsoft.Data.ConnectionUI;

DataConnectionDialog dialog = new DataConnectionDialog();

dialog.DataSources.Add(DataSource.SqlDataSource);
            dialog.SelectedDataProvider = DataProvider.SqlDataProvider;

//dialog.DataSources.Add(DataSource.OdbcDataSource);

//dialog.SelectedDataSource = DataSource.OdbcDataSource;
            //dialog.SelectedDataProvider = DataProvider.OdbcDataProvider;

dialog.StartPosition = FormStartPosition.CenterScreen;
            dialog.Title = "Connect to SqlServer";
            dialog.ConnectionString = "server=127.0.0.1;database=YarnNew;user id=sa;password=aaa;";

if (DataConnectionDialog.Show(dialog, this) == DialogResult.OK)
            {
                MessageBox.Show(dialog.ConnectionString);
            }
