动态改变的connectionString在web.config中 [英] Dynamically change connectionString in web.config

问题描述

我在我的web.config以下

I have the following in my web.config

<connectionStrings>
   <add name="ActiveDirectoryConnection" connectionString="LDAP://ActiveDirectoryDomain1.com" providerName="System.Web.Security.ActiveDirectoryMembershipProvider"/>
</connectionStrings>

我需要一个下拉框添加到我的登录页面，允许用户向的connectionString更改为不同的字符串，例如LDAP：//ActiveDirectoryDomain2.com

I need to add a dropdown box to my login page that allows the user to change the connectionString to a different string, e.g. "LDAP://ActiveDirectoryDomain2.com"

在背后如何更改连接字符串值？C＃code

In C# code behind how do change the connectionString value?

我遇到的问题是，有4个其他的web.config设置调用一个的connectionString。例如：

The problem I am having is that there are 4 other web.config settings call that one connectionString. For example:

<activeDirectorySecurityContextSettings connectionStringName="ActiveDirectoryConnection" defaultADUserName="ReportUser" defaultADPassword="password"/>  

谢谢！

推荐答案

如果一个用户能够更改设置的值，则web.config文件是错误的地方保存设置。

If a user is able to change the value of the Setting, then the web.config file is the wrong place to store the setting.

您应该检查出一个用户级范围的值设置文件来代替。

You should check out a User Scoped value in a Settings file instead.

MSDN - 在C＃使用设置

在使用这样的设置，改变在运行时的值很简单：

When using settings like this, changing the value at runtime is easy:

Properties.Settings.Default.LdapConnectionString = "New Connection String";
Properties.Settings.Default.Save();
