语法

声明
Public ReadOnly Property InnerObject As Object
    Get
用法
Dim instance As ForEachEnumeratorHost
Dim value As Object

value = instance.InnerObject

public Object InnerObject { get; }

public:
virtual property Object^ InnerObject {
    Object^ get () sealed;
}

abstract InnerObject : Object
override InnerObject : Object

final function get InnerObject () : Object

属性值

类型：System. . :: . .Object
An object.

实现

IDTSObjectHost. . :: . .InnerObject

示例

Several classes are created and by the ForEachEnumeratorHost. The following code example shows the enumerators currently available to the application, how to create the ForEachSMOEnumerator within the host object, and then cast the InnerObject to the specific enumerator type.

using System;
using System.Collections.Generic;
using System.Text;
using Microsoft.SqlServer.Dts.Runtime.Enumerators.SMO;
using Microsoft.SqlServer.Dts.Runtime;


namespace Microsoft.SqlServer.SSIS.Samples
{
    internal class EnumType
    {
        public const string SMOEnum = "Foreach SMO Enumerator";
    }
    class Program
    {
        static void Main(string[] args)
        {
            Application app = new Application();
            ForEachEnumeratorInfos infos = app.ForEachEnumeratorInfos;
            ForEachEnumeratorInfo info = null;

            foreach (ForEachEnumeratorInfo enumInfo in infos)
            {
            Console.Write("Available enumerators: {0}\n", enumInfo.Name);
            // When the SMO enumerator is found, set the info variable.
            if (enumInfo.Name == EnumType.SMOEnum)
            {  
                info = enumInfo;
            }
        }

        ForEachEnumeratorHost enumH = info.CreateNew();
        Console.WriteLine("SMO Enumerator: " + enumH.InnerObject.ToString());
        ForEachSMOEnumerator smoEnumerator = (ForEachSMOEnumerator)enumH.InnerObject;
        }
    }
}

            End If
            Next

        Dim EnumH As ForEachEnumeratorHost =  info.CreateNew() 
        Dim enumH As ForEachEnumeratorHost =  info.CreateNew()

        Console.WriteLine("SMO Enumerator: " + EnumH.InnerObject.ToString()) 
        Console.WriteLine("SMO Enumerator: " + enumH.InnerObject.ToString())
        End Enum
        Dim smoEnumerator As ForEachSMOEnumerator = CType(EnumH.InnerObject, ForEachSMOEnumerator)
        Dim smoEnumerator As ForEachSMOEnumerator = CType(enumH.InnerObject, ForEachSMOEnumerator)
        End Enum
        End Sub
    End Class
End Namespace

Sample Output:

Available enumerators: Foreach File Enumerator

Available enumerators: Foreach Item Enumerator

Available enumerators: Foreach ADO Enumerator

Available enumerators: Foreach ADO.NET Schema Rowset Enumerator

Available enumerators: Foreach From Variable Enumerator

Available enumerators: Foreach NodeList Enumerator

Available enumerators: Foreach SMO Enumerator

SMO Enumerator: Microsoft.SqlServer.Dts.Runtime.Enumerators.SMO.ForEachSMOEnumerator

SMO.EnumURN = RuntimeServer[@Variable='MachineName']/Server[@Name='localhost']/SMOEnumObj[@Name='Databases']/SMOEnumType[@Name='Names']
