在该代码中我有域名，用户名和密码TextBox。它们将在ldap中进行身份验证。
这里是我的ldapauthentication.cs代码：
使用系统;
使用 System.Text;

public bool IsAuthenticated（ string domain， string username， string pwd）

string _domain = domain;
string domainAndUsername = domain + @ \\ \\ +用户名;
DirectoryEntry entry = new DirectoryEntry（_path，domainAndUsername，pwd）;
尝试
{
// 绑定到原生AdsObject以强制进行身份验证。

尝试

int propertyCount = result.Properties [ 成员]计数。
string dn;
int equalsIndex，commaIndex;

如何使用登录表单的值来更改密码表格？
i想要更改密码。
我尝试了什么：
我尝试制作新参数，但我仍然感到困惑。
我只想取旧密码的价值并将其更改为新密码。
有人可以帮助我吗？
解决方案
你可以在Session中存储旧密码。其他选项是使用Profile Provider或者创建一个包含登录后所需信息的自定义类。您还可以查看ASP.NET标识以添加自定义声明。但出于安全考虑，我宁愿让用户输入旧密码来更改新密码。
我建议您必须要求旧密码更改密码
另外明智的是，如果你只是想用登录来改变它，那么你需要使用Section
基本上是将数据从一个表单传递给另一个表单你可以在任何地方调用session
在会话变量中添加值
Session.Add（ Programe，ddlProgamme.SelectedValue）;
程序是会话变量的名称
它的数据类型默认为字符串
从会话变量中获取值
此 .program =（ string ）（会话[ Programe ]） ;
I have code right here:

in that code i have domain, username and password TextBox. And they will be authenticated in ldap.
here's my ldapauthentication.cs code:
using System;
using System.Text;
using System.Collections;
using System.DirectoryServices;
using System.DirectoryServices.AccountManagement;
using System.DirectoryServices.ActiveDirectory;
namespace FormsAuth
{
public class LdapAuthentication
{
private string _path;
private string _filterAttribute;
public LdapAuthentication(string path)
{
_path = path;
}
public bool IsAuthenticated(string domain, string username, string pwd)
{
string _domain = domain;
string domainAndUsername = domain + @"\" + username;
DirectoryEntry entry = new DirectoryEntry(_path, domainAndUsername, pwd);
try
{
//Bind to the native AdsObject to force authentication.
object obj = entry.NativeObject;
DirectorySearcher search = new DirectorySearcher(entry);
search.Filter = "(SAMAccountName=" + username + ")";
search.PropertiesToLoad.Add("cn");
SearchResult result = search.FindOne();
if (null == result)
{
return false;
}
//Update the new path to the user in the directory.
_path = result.Path;
_filterAttribute = (string)result.Properties["cn"][0];
}
catch (Exception ex)
{
throw new Exception("Error authenticating user. " + ex.Message);
}
return true;
}
public string GetGroups()
{
DirectorySearcher search = new DirectorySearcher(_path);
search.Filter = "(cn=" + _filterAttribute + ")";
search.PropertiesToLoad.Add("memberOf");
StringBuilder groupNames = new StringBuilder();
try
{
SearchResult result = search.FindOne();
int propertyCount = result.Properties["memberOf"].Count;
string dn;
int equalsIndex, commaIndex;
for (int propertyCounter = 0; propertyCounter < propertyCount; propertyCounter++)
{
dn = (string)result.Properties["memberOf"][propertyCounter];
equalsIndex = dn.IndexOf("=", 1);
commaIndex = dn.IndexOf(",", 1);
if (-1 == equalsIndex)
{
return null;
}
groupNames.Append(dn.Substring((equalsIndex + 1), (commaIndex - equalsIndex) - 1));
groupNames.Append("|");
}
}
catch (Exception ex)

throw new Exception("Error obtaining group names. " + ex.Message);

return groupNames.ToString();

how can i use the value of logon form in to change password form?
i want to change password.
What I have tried:
I tried to make new parameters, but i still confuse.
I just want to take value of old password and change it to new password.
can somebody help me?
解决方案
You could store the old password in Session. Other option is to use Profile Provider or perhaps creating a custom class that holds the information you need after logon. You can also look into ASP.NET Identity to add custom claims. But I would prefer to let the user type their old password for changing new password for security reasons.
i suggest you that you must ask old password to change password
other wise if you just want to change it with logon so you need to use Section
basically section is pass data from one form to other and you can call session any where
To add value in session variable
Session.Add("Programe", ddlProgamme.SelectedValue);
"Program" is a name of session variable
it's data type is by default string
To Get value from session variable
this.program = (string)(Session["Programe"]);
