推荐答案

您可以做到这一点通过一些COM Introp ......但你必须要拉了一堆互操作程序集到您的项目，可以是一个拖累。这code将使用反射，而不是显示对话框。

You can do it through some COM Introp...but then you have to pull in a bunch of Interop assemblies into your project which can be a drag. This code will show the dialog using reflection instead.

public static string ShowDialog( IWin32Window owner,
                                 string connectionString )
{
    Type dlType = Type.GetTypeFromProgID( "DataLinks", true );
    Type acType = Type.GetTypeFromProgID( "ADODB.Connection", true );

    object form = Activator.CreateInstance( dlType );
    object connection = Activator.CreateInstance( acType );

    acType.InvokeMember(
        "ConnectionString",
        BindingFlags.Public | BindingFlags.SetProperty,
        null,
        connection,
        new object[]{ connectionString }
        );
    object result =
    dlType.InvokeMember(
        "PromptEdit",
        BindingFlags.Public | BindingFlags.InvokeMethod,
        null,
        form,
        new object[]{ connection }
        );
    if( result != null && (bool)result )
        return acType.InvokeMember(
    	            "ConnectionString",
    	            BindingFlags.Public | BindingFlags.GetProperty,
    	            null,
    	            connection,
    	            new object[]{} ) as string;

    return null;
}

这基本上转化为下面的VB脚本

This basically translates to the following VB Script

form = GetObject( "DataLinks" )
connection = GetOBject( "ADODB.Connection" )
connection.ConnectionString = "existing connection"
form.PromptEdit( connection )
Return connection.ConnectionString
