找高人 关于用C# 编程 !@!!!!!!!!!!!!!!!!!!!!!
我用的是这个 API 函数 public virtual new void NtAccountCreate ( System.String bstrDomain , System.String bstrUserLogin , System.String bstrPassword , System.String bstrUserComment , System.String bstrLocalGroup )
using System;
using System.Collections;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Web;
using System.Web.SessionState;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.HtmlControls;
using MSExchangeAcctLib;
namespace exchangetest
{
/// <summary>
/// Summary description for WebForm1.
/// </summary>
public class WebForm1 : System.Web.UI.Page
{
protected System.Web.UI.WebControls.Button Button1;
public MSExchangeAcctLib.IAcctMgmt sd;
private void Button1_Click(object sender, System.EventArgs e)
{
//sd.NtAccountDelete( "utpcb.com ", "py-wang ");
sd.NtAccountCreate( "域名 ", "管理员账号 ", "密码 ", "新加的用户 ", "所属的组 ");
TextBox1.Text= "nihao ";
}
private void Page_Load(object sender, System.EventArgs e)
{
// Put user code to initialize the page here
}
#region Web Form Designer generated code
override protected void OnInit(EventArgs e)
{
//
// CODEGEN: This call is required by the ASP.NET Web Form Designer.
InitializeComponent();
base.OnInit(e);
}
/// <summary>
/// Required method for Designer support - do not modify
/// the contents of this method with the code editor.
/// </summary>
private void InitializeComponent()
{
this.Button1.Click += new System.EventHandler(this.Button1_Click);
this.Load += new System.EventHandler(this.Page_Load);
}
#endregion
}
}
我的目的很简单 就是按下BUTTON就能加入我写入的用户名和密码
环境是 WIN2000 2003.NET
我运行点BUTTON后出现以下错误

MSExchangeAcctLib 这个类是从MS网站下的一个域的接口
如果説是
sd没有实例化啊，是null
public MSExchangeAcctLib.IAcctMgmt sd;
你只有定义，并没有给它初始化，自然会报错了
怎麽實例話啊？？
[解决办法]
没用过，帮UP

sd.NtAccountCreate
这个在哪个类里实现的,就按哪个类实例化贝
