直接调用内置数据源连接对话框（C#/VB.NET2005源码）

'先引用Microsoft.Data.ConnectionUI.Dialog.dll（在VS2005安装路径的IDE目录下）
'将以下代码加入相应事件过程
Dim dialog As DataConnectionDialog = New DataConnectionDialog()
dialog.DataSources.Add(DataSource.SqlDataSource)
dialog.DataSources.Add(DataSource.OdbcDataSource)
dialog.DataSources.Add(DataSource.OracleDataSource)
dialog.DataSources.Add(DataSource.AccessDataSource)

dialog.SelectedDataSource = DataSource.SqlDataSource
dialog.SelectedDataProvider = DataProvider.SqlDataProvider

DataConnectionDialog.Show(dialog)
If dialog.DialogResult = Windows.Forms.DialogResult.OK Then
Me.TextBox1.Text = dialog.ConnectionString
ElseIf dialog.DialogResult = Windows.Forms.DialogResult.Cancel Then
Me.Close()
End If

谢谢 Tonyyang 转为C#，在此一并归纳，但此C#代码我没有测试过，请发现问题的同行指正：

C#2005 Code

DataConnectionDialog dialog = new DataConnectionDialog();
dialog.DataSources.Add(DataSource.SqlDataSource);
dialog.DataSources.Add(DataSource.OdbcDataSource);
dialog.DataSources.Add(DataSource.OracleDataSource);
dialog.DataSources.Add(DataSource.AccessDataSource);

dialog.SelectedDataSource = DataSource.SqlDataSource;
dialog.SelectedDataProvider = DataProvider.SqlDataProvider;

DataConnectionDialog.Show(dialog);
if (dialog.DialogResult == DialogResult.OK)
{ textBox1.Text = dialog.ConnectionString; }
else if (dialog.DialogResult == DialogResult.Cancel)
{ }
//Me.Close();
