读取config文件的两种方法

项目进入测试阶段,暂时闲下来了,写点笔记.

读取web.config 或者 app.config中自定义配置的值的属性,常用2种方法.

假设有如下配置:

<appSettings>

<add key="A" value="config with A"/>

<add key="B" value="config with B"/>

</appSettings>

using System.Configuration;

[A] 方法

string strTest = ConfigurationSettings.AppSettings["A"]; // get A 's value

[B] 方法

AppSettingsReader appReader = new AppSettingsReader();

string strTest = appReader.GetValue(strKey,typeof(string)).ToString();

e.g.

private string GetConfig(string strKey)

{

AppSettingsReader appReader = new AppSettingsReader();

string strReturn;

try

{

strReturn = appReader.GetValue(strKey,typeof(string)).ToString();

}

catch(Exception ex)

{

strReturn = ex.Message.ToString();

}

finally

{

appReader = null;

}

return strReturn;

}
