背景：
以工作组的方式在服务器A上架设了TFS2008，分配给组员的帐户是服务器A的本地帐户，在这种情况下，组员如果想要修改密码，就需要提供一个修改的平台。
首先想到的是，在TFS的Sharepoint门户上集成修改密码的页面，但是很遗憾，在网上找到的Web part控件都有些问题，实在不行了，就只好自己单独弄了一个ASP.NET页面，其实还是使用DirectoryEntry来使用修改。修改密码的命令有"ChangePassword"和"SetPassword"，这两个命令的区别在于：
"ChangePassword"需要旧密码，它对于修改密码的帐户没有要求。
"SetPassword"不需要旧密码，但它要求被修改的用户拥有管理员权限。
最后选择使用ChangePassword，码如下：
Default.aspx.cs
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using System.DirectoryServices; namespace ChangePwd { public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { lableUserName.Text = Environment.UserName; } protected void btnChangePwd_Click(object sender, EventArgs e) { string oldPassword = textOldPwd.Text.Trim(); string newPassword = textNewPwd.Text.Trim(); string newPassword2 = textNewPwd2.Text.Trim(); if (oldPassword == newPassword) { lableMSG.Text = "新密码与旧密码不能相同"; return; } lableMSG.Text = ChangePassword(Environment.UserName, oldPassword, newPassword); } private string ChangePassword(string username, string oldpass, string newpass) { string machineAndUser = Environment.MachineName + "\\" + username; string adsPath = String.Format("WinNT://{0}/{1}, user", Environment.MachineName, username); DirectoryEntry user = new DirectoryEntry(adsPath, machineAndUser, oldpass, AuthenticationTypes.Secure); try { user.Invoke("ChangePassword", new object[] { oldpass, newpass }); return string.Format("更改密码成功"); } catch (Exception ex) { string message = ex.Message; while ((ex = ex.InnerException) != null) { message += ":: " + ex.Message; } return message; } finally { user.Dispose(); } } } }
