Question

我正在尝试创建OracleConnectionStringBuilder或SqlConnectionStringBuilder的新对象，具体取决于发送给函数的数据库提供程序。

无法弄清楚如何以最短（和可读）的方式做到这一点。

我从：

开始

var isIntegratedSecuritySet = string.IsNullOrEmpty(UserId) || string.IsNullOrEmpty(Password);
var connBuilder = new SqlConnectionStringBuilder()
    {
        DataSource = DataSource,
        UserID = UserId,
        Password = Password,
        InitialCatalog = InitialCatalog,
        ConnectTimeout = 15,
        IntegratedSecurity = isIntegratedSecuritySet
    };

    return connBuilder.ConnectionString;
}

但是现在Oracle没有IntegratedSecurity，它有PersistSecurityInfo。

所以我试试这个：

var isIntegratedSecuritySet = string.IsNullOrEmpty(UserId) || string.IsNullOrEmpty(Password);
var connBuilder = new DbConnectionStringBuilder();

try
{
    if (Providor.Equals(DatabaseProvidors.Oracle))
    {
        connBuilder = new OracleConnectionStringBuilder()
        {

            PersistSecurityInfo = isIntegratedSecuritySet
        };
    }
    else if (Providor.Equals(DatabaseProvidors.SqlServer))
    {
        connBuilder = new SqlConnectionStringBuilder()
        {
            IntegratedSecurity = isIntegratedSecuritySet
        };
    }

但现在我需要将属性转换为一个或另一个

((SqlConnectionStringBuilder)connBuilder).DataSource = DataSource;

等。

如果能够以完整的形式明确定义这两者，我能做什么才能做到这一点：

var isIntegratedSecuritySet = string.IsNullOrEmpty(UserId) || string.IsNullOrEmpty(Password);

try
{
    if (Providor.Equals(DatabaseProvidors.Oracle))
    {
        var connBuilder = new OracleConnectionStringBuilder()
        {
            DataSource = DataSource,
            UserID = UserId,
            Password = Password,
            ConnectionTimeout = 15,
            PersistSecurityInfo = isIntegratedSecuritySet
        };

        //if (InitialCatalog != null)
        //    connBuilder.InitialCatalog = InitialCatalog;
        return connBuilder.ConnectionString;
    }
    else if (Providor.Equals(DatabaseProvidors.SqlServer))
    {
        var connBuilder = new SqlConnectionStringBuilder()
        {
            DataSource = DataSource,
            UserID = UserId,
            Password = Password,
            ConnectTimeout = 15,
            IntegratedSecurity = isIntegratedSecuritySet
        };

        if (InitialCatalog != null)
            connBuilder.InitialCatalog = InitialCatalog;

        return connBuilder.ConnectionString;
    }
}

为什么不使用通用DbConnectionStringBuilder？

var connBuilder = new System.Data.Common.DbConnectionStringBuilder();

connBuilder.Add("Data Source", DataSource);
connBuilder.Add("User Id", UserId);
connBuilder.Add("Password", Password);

if (Providor.Equals(DatabaseProvidors.Oracle)) {
   connBuilder.Add("Persist Security Info", isIntegratedSecuritySet);
   connBuilder.Add("Connection Timeout", ConnectionTimeout);
} else if (Providor.Equals(DatabaseProvidors.SqlServer)) {
   connBuilder.Add("Integrated Securiry", isIntegratedSecuritySet);
   connBuilder.Add("Connect Timeout", ConnectionTimeout); // Not sure about this property
}

在同一个调用中使用Oracle / SQLConnectionstringBuilder
