winform调用config文件

 

<?xml version="1.0" encoding="utf-8" ?><configuration>  <connectionStrings>    <add name="zxz" connectionString="Data Source=192.168.1.81;Database=SMRS;User id=sa;PWD=reasee#1206"providerName="System.Data.SqlClient" />  </connectionStrings>  <appSettings>    <add key="ConnectionString" value="Server=192.168.1.81;user id=sa;password=reasee#1206;database=SMRS"/>  </appSettings></configuration> 

在方案里添加：1）添加引用System.Configuration

2）在.CS文件头上加上 using System.Configuration;

 项目中调用：如果是connectionStrings，用ConfigurationManager.ConnectionStrings["add的name"].ConnectionString;

如果是appSettings，用ConfigurationManager.AppSettings["add的key"].ToString();

如：public static string SqlConnString = ConfigurationManager.AppSettings["ConnectionString"].ToString();
