C＃在winform的app.config [英] C# app.config in winform

问题描述

我通常使用一个文本文件作为一个配置。但是这一次，我想利用的app.config到一个文件名（键）与名称（值）相关联，并在组合框中的名称

I usually use a text file as a config. But this time I would like to utilize app.config to associate a file name (key) with a name (value) and make the names available in combo box

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <appSettings>
   <add key="Scenario1.doc" value="Hybrid1"/>
   <add key="Scenario2.doc" value="Hybrid2"/>
   <add key="Scenario3.doc" value="Hybrid3"/>
</appSettings>
</configuration>

将这项工作？如何找回数据？

will this work? how to retrieve the data ?

推荐答案

直接从的文档：

// Get the AppSettings section.        
// This function uses the AppSettings property
// to read the appSettings configuration 
// section.
public static void ReadAppSettings()
{
  try
  {
    // Get the AppSettings section.
    NameValueCollection appSettings =
       ConfigurationManager.AppSettings;

    // Get the AppSettings section elements.
    Console.WriteLine();
    Console.WriteLine("Using AppSettings property.");
    Console.WriteLine("Application settings:");

    if (appSettings.Count == 0)
    {
      Console.WriteLine("[ReadAppSettings: {0}]",
      "AppSettings is empty Use GetSection command first.");
    }
    for (int i = 0; i < appSettings.Count; i++)
    {
      Console.WriteLine("#{0} Key: {1} Value: {2}",
        i, appSettings.GetKey(i), appSettings[i]);
    }
  }
  catch (ConfigurationErrorsException e)
  {
    Console.WriteLine("[ReadAppSettings: {0}]",
        e.ToString());
  }
}

所以，如果你要访问的设置 Scenario1.doc ，你可以这样做：

VAR值= ConfigurationManager.AppSettings [Scenario1 .DOC];

编辑：

加布里埃尔通用在说评论，你将不得不增加 System.Configuration 引用。

As Gabriel GM said in the comments, you will have to add a reference to System.Configuration.
