Question

我想从ConnectionString的{{1}}实例中获取SqlConnectionStringBuilder。

这看起来很简单，应该像这样简单：

String

但String conString = builder.ConnectionString;放弃的String并未包含SqlConnectionStringBuilder字段/值。我猜这是某种安全功能，有没有办法强制Password加入Password？

进一步观察我认为这可能与String有关。我要做的是修改ConnectionManager的{{1}}，更改ConnectionString。

以下是我的代码，Package的连接字符串被传回Initial Catalog的密码丢失了......

builder

Answer 1

在SqlConnectionStringBuilder中设置其他属性之前将PersistSecurityInfo设置为True：D

Answer 2

我需要稍微重命名一下，因为问题现在不同了，但这是我的解决方案：

@ madd0正确回答了这个问题的第一部分。 ConnectionString确实包含Password字段。

第二部分解决了格式化代码如下：

public void DataTransfer(String sourceConnection, String destConnection, String pkgLocation)
{     
    Package pkg;
    Application app;
    DTSExecResult pkgResults;

    try
    {
        app = new Application();
        pkg = app.LoadPackage(pkgLocation, null);

        foreach (ConnectionManager connectionManager in pkg.Connections)
        {
            SqlConnectionStringBuilder builder;
            switch (connectionManager.Name)
            {
                case "SourceConnection":
                    builder = new SqlConnectionStringBuilder(sourceConnection) { PersistSecurityInfo = true };
                    builder.Remove("Initial Catalog");
                    builder.Add("Initial Catalog", "StagingArea");
                    var sourceCon = builder.ConnectionString + ";Provider=SQLNCLI;Auto Translate=false;";
                    //Added spaces to retain password!!!
                    sourceCon = sourceCon.Replace(";", "; ");
                    connectionManager.ConnectionString = sourceCon;
                    Debug.WriteLine(connectionManager.ConnectionString.ToString());
                    break;
                case "DestinationConnection":
                    builder = new SqlConnectionStringBuilder(sourceConnection) { PersistSecurityInfo = true };
                    builder.Remove("Initial Catalog");
                    builder.Add("Initial Catalog", "StagingArea");
                    var destCon = builder.ConnectionString + ";Provider=SQLNCLI;Auto Translate=false;";
                    //Added spaces to retain password!!!
                    destCon = destCon.Replace(";", "; ");
                    connectionManager.ConnectionString = destCon;
                    Debug.WriteLine(connectionManager.ConnectionString.ToString());
                    break;
            }
        }
        pkgResults = pkg.Execute();
    }
    catch (Exception e)
    {

        throw;
    }
    Console.WriteLine(pkgResults.ToString());
}

我使用ConnectionString玩了一段时间后注意到原来的String在每个属性之间都有空格。

运行2次测试我发现没有空格Password丢失了......

connectionManager.ConnectionString = destCon;

测试1：没有空格：

当destCon = Data Source=xxx.xxx.xxx.xxx;Initial Catalog=StagingArea;User ID=*****;Password=*****;Provider=SQLNCLI;Auto Translate=false;

时

然后connectionManager.ConnectionString = Data Source=xxx.xxx.xxx.xxx;User ID=*****;Initial Catalog=StagingArea;Provider=SQLNCLI;Auto Translate=false;

测试2：空格：

当destCon = Data Source=xxx.xxx.xxx.xxx; Initial Catalog=StagingArea; User ID=*****; Password=*****; Provider=SQLNCLI; Auto Translate=false;

时

然后connectionManager.ConnectionString = Data Source=xxx.xxx.xxx.xxx; Initial Catalog=StagingArea; User ID=*****; Password=*****; Provider=SQLNCLI; Auto Translate=false;

不知道为什么会发生这种情况，但如果没有空格，则会调整排序并丢失Password字段。

将ConnectionString从SqlConnectionSringBuilder传递到ConnectionManager
