在后面的代码中更改web.config设置 [英] change web.config settings in code behind

问题描述

我使用第三方上传控件，并且web.config中的设置很少

i m using a third party upload control and there r few settings in web.config

<uploadSettings allowedFileExtensions=".pdf,.xls,.doc,.zip,.rar,.jpg" scriptPath="upload_scripts" imagePath="" cssPath="upload_styles" enableManualProcessing="true" showProgressBar="true" showCancelButton="true"/>

现在，我想从后面的代码中更改这些设置，例如，我想将showcancelbutton ="false"

now i want to change these settings from code behind e.g i want to make showcancelbutton="false"

我该怎么做

推荐答案

由于它是Web应用程序，因此您需要更改.我将使用WebConfigurationManager.

Since it's a web application you want to change I'd go with the WebConfigurationManager.

如果您要更改的配置值在单独的部分中，则需要先获取该部分:

If the configuration value you are about to change is in a separate section you need to get that section first:

var myConfiguration = (Configuration)WebConfigurationManager.OpenWebConfiguration("~");
var section = (MySectionTypeHere)myConfiguration.GetSection("system.web/mySectionName");
//Change your settings here
myConfiguration.Save();

请记住，每次更改web.config时都会重新启动Web应用程序.

Keep in mind that the web application will be restarted each time you change the web.config.
