1、在vs（此处目录文件以vs2010为例）安装目录下（“%visual studio安装目录%/common10/ide/microsoft.data.connectionui.dialog.dll”）找到microsoft.data.connectionui.dll、microsoft.data.connectionui.dialog.dll和汉化资源文件microsoft.data.connectionui.dialog.resources.dll，注意汉化资源文件需要放在zh-chs文件夹下；
2、在工程文件中添加对以上二个dll文件的引用；
3、具体代码如下：
private void button1_click(object sender, eventargs e) { dataconnectiondialog dialog = new dataconnectiondialog(); dialog.datasources.add(datasource.accessdatasource); dialog.datasources.add(datasource.odbcdatasource); dialog.datasources.add(datasource.oracledatasource); dialog.datasources.add(datasource.sqldatasource); dialog.datasources.add(datasource.sqlfiledatasource); dialog.selecteddatasource = datasource.sqldatasource; dialog.selecteddataprovider = dataprovider.sqldataprovider; if (dataconnectiondialog.show(dialog, this) == dialogresult.ok) { //conndlg.connectionstring; } }
运行效果：
重新打开时展示，之前选择的连接字符串：
dataconnectiondialog dialog = new dataconnectiondialog(); dialog.datasources.add(datasource.accessdatasource); dialog.datasources.add(datasource.odbcdatasource); dialog.datasources.add(datasource.oracledatasource); dialog.datasources.add(datasource.sqldatasource); dialog.datasources.add(datasource.sqlfiledatasource); dialog.selecteddatasource = datasource.sqldatasource; dialog.selecteddataprovider = dataprovider.sqldataprovider; //之前 dataconnectiondialog 控件保存的连接字符串 dialog.connectionstring = str; //connectionstring有值，则会显示出来 dataconnectiondialog.show(dialog, this);
以上就是使用visual studio的动态连接库创建通用数据库连接对话框的内容。
