命名空间：  Microsoft.SqlServer.Dts.Runtime
程序集：  Microsoft.SqlServer.ManagedDTS（在 Microsoft.SqlServer.ManagedDTS.dll 中）

语法

声明
Public Function AcquireConnection ( _
    txn As Object _
) As Object
用法
Dim instance As ConnectionManager
Dim txn As Object
Dim returnValue As Object

returnValue = instance.AcquireConnection(txn)

public Object AcquireConnection(
    Object txn
)

public:
Object^ AcquireConnection(
    Object^ txn
)

member AcquireConnection : 
        txn:Object -> Object 

public function AcquireConnection(
    txn : Object
) : Object

参数

返回值

类型：System. . :: . .Object
An object that contains the transaction connection.

注释

Pass null Nothing nullptr unit null 引用（在 Visual Basic 中为 Nothing） for the transaction parameter txn when the SupportsDTCTransactions property is false. If the SupportsDTCTransactions property is true, you can pass null Nothing nullptr unit null 引用（在 Visual Basic 中为 Nothing） in the transaction parameter to indicate that the container supports transactions, but is not going to participate.

示例

The following code example shows how to add the OLE DB connection to the connection manager and acquire the connection.

// Create the package.
Package pkg = new Package();

// Add a ConnectionManager to the Connections collection.
ConnectionManager connMgr = pkg.Connections.Add("ADO.NET:OLEDB");
connMgr.Properties["RetainSameConnection"].SetValue(connMgr , true);
connMgr.ConnectionString = connStr;

// Aqcuire the connection.
object connection = connMgr.AcquireConnection(null);

' Create the package.
Dim pkg As Package =  New Package() 
 
' Add a ConnectionManager to the Connections collection.
Dim connMgr As ConnectionManager =  pkg.Connections.Add("ADO.NET:OLEDB") 
connMgr.Properties("RetainSameConnection").SetValue(connMgr , True)
connMgr.ConnectionString = connStr
 
' Aqcuire the connection.
Dim connection As Object =  connMgr.AcquireConnection(Nothing)
