Question

以下是我的app.config文件的片段。

<MyProject>
    <ConnectionStrings>
    ...      
    <Operational providerType="SqlServer" provider="" dataSource="<ServerName>" initialCatalog="<DBName>" security="" userName="<SomeUser>" password="<Password>" />
    ...
    </ConnectionStrings>
</MyProject>

在我的C＃代码中，我在某个变量中提供了此值，例如......

string OperationalConnectionConfiurationPath = "MyProject/ConnectionStrings/Operational";

如何从中获取我的SqlConnection对象？

Answer 1

connectionStrings是configuration部分的孩子。摆脱那些<MyProject>的东西。

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <connectionStrings>
    <add name="Operational" connectionString="Data Source=SERVER_NAME;Initial Catalog=DB_NAME;User Id=USER_ID;Password=PASSWORD;" providerName="System.Data.SqlClient" />
  </connectionStrings>
</configuration>

您可以通过以下方式获取连接字符串：

using System.Configuration;

var connectionString = ConfigurationManager.ConnectionStrings["Operational"].ConnectionString;

C＃连接字符串 - 从配置部分获取
