c# – 将字符串转换为ConnectionStringSettings

在我的项目中,我有一个需要返回ConnectionStringSettings对象的方法.由于数据库和服务器名称将动态更改,我需要动态
构造连接字符串.

如何将字符串转换为ConnectionStringSettings？

public ConnectionStringSettings getConnection(string server,string database)
{
    //ConnectionStringSettings connsettings = new ConnectionStringSettings();

    string connection = ConfigurationManager.ConnectionStrings["myConnString"].ToString();
    connection = string.Format(connection,server,database);

    // Need to convert connection to ConnectionStringSettings
    // Return ConnectionStringSettings
}

–Web.config

<add name="myConnString" connectionString="server={0};Initial Catalog={1};uid=user1;pwd=blah; Connection Timeout = 1000"/>

解决方法

ConnectionStringSettings类构造函数有一个带有两个字符串的重载(第一个是连接字符串的名称,第二个是连接字符串本身).

public ConnectionStringSettings getConnection(string server,string database)
{
    string connection = ConfigurationManager.ConnectionStrings["myConnString"].ToString();
    connection = string.Format(connection,database);

    return new ConnectionStringSettings("myConnString",connection);
}

有一个third overload,它为提供者的名称提供了一个额外的字符串.
