将字符串转换为ConnectionStringSettings

Question

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string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
}

- 的Web.config

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

Answer 1

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, server, database);

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

有一个third overload，它为提供者的名称提供了额外的字符串。
